President Biden signs an executive order on the Paris climate agreement

What Biden Re-joining the Paris Agreement Means for Climate Action

By Nicole Lim

As you may have heard by now, newly inaugurated President Biden returned the United States to the Paris Agreement. This will officially take effect in 30 days. The President also signed executive orders [1] overturning some of Trump’s other policies that had environmental implications, including putting a halt to the controversial Keystone XL pipeline.

Since Biden first announced [2] that re-joining the Paris Agreement would be one of his first moves in office, many have been anticipating this day. For climate action and for many other reasons, today was a day that marked the beginning of a new era.

But beyond the politics and symbolism of it all, we wanted to take a look at what this all means for climate action and sustainability.

Ambition, leadership and science

As world’s second largest emitter of greenhouse gas emissions (GHG), behind China, the U.S. re-joining the Paris Agreement must come with bold and decisive commitments and plans to significantly reduce GHG emissions. When the U.S. first joined the Paris Agreement under the Obama Administration, the U.S. had pledged to reduce emission levels between 26-28% by 2025 from 2005 levels. At present, it is not on track to reach those goals.

Much has changed since then, and Biden will now be expected to raise the bar by setting more ambitious targets that capture its “fair share” of emissions. Not only that, with China announcing its commitment to be net-zero by 2060 [3], the E.U. to be the same by 2050 [4], and many other net-zero commitments by strong Asian economies, the pressure is on for the U.S. to take on an increased leadership role.

Thankfully, science, as Mr. Biden indicated in his executive order, would guide U.S.’s climate action.


It is, therefore, the policy of my Administration to listen to the science.

Executive Order, 20 Jan 2021

Therefore, we can minimally expect that Washington will set targets in line with the Intergovernmental Panel on Climate Change’s (IPCC) guidance on reducing GHG emissions by 45% by 2030 (from 2010 levels) and reaching net-zero by 2050.

Organisations and corporations often adopt or align with national climate targets. With the U.S. being a crucial player in the global economy, their targets send signals and inform how the private sector globally might respond to climate change.

Climate finance and pricing carbon

A striking feature of Mr. Biden’s executive order was Sec. 5.  Accounting for the Benefits of Reducing Climate Pollution. It requires all agencies to capture the full costs of GHGs through incorporating the social cost of carbon” (SCC), “social cost of nitrous oxide” (SCN), and “social cost of methane” (SCM) into cost-benefit analyses in decision-making. To facilitate this, the President has established an Interagency Working Group on the Social Cost of Greenhouse Gases, led by economists and scientists.

The Working Group has been tasked to publish an interim SCC, SCN, and SCM within 30 days (by 21 February 2021), and establish a final SCC, SCN, and SCM no later than January 2022. These costs will be used by agencies in valuing GHGs from change in regulation and other relevant agency actions. The Working Group will also be providing recommendations to the President on where and how these costs can be applied in decision-making.

Mr. Biden also made clear that these costs are to “reflect the interests of future generations in avoiding threats posed by climate change”.

The President also has a $2 trillion plan to invest in the transition from fossil fuels to clean energy [5]. This plan will see the transformation of the U.S. automotive industry to produce increased zero-emission / electric vehicles, green infrastructure, carbon-neutral power, energy-efficient buildings, investment in green innovation, clean agriculture and job creation. Since Biden’s announcement, stock prices of ESG companies that stand to benefit in a decarbonised world have soared [6]. We can expect to see these sustainable, ESG-focused companies to be at the forefront in the coming years.

Ahead of stronger sustainability and ESG regulation, companies are already bracing themselves for increased expectations [7], and some trade groups and organisations have begun meeting with the Biden team to review ESG matters and potential risks.

Outside U.S. shores and as part of commitments under the Paris Agreement, the U.S. will also be expected to play a big role in helping developing nations finance a fair, just and equitable shift away from carbon-intensive industries and fossil fuels.

Moves to watch

So much today, but it is only the beginning. Moving ahead, there are many developments to look forward to.

With COP26 around the corner, it is likely that we will see the U.S. and its newly assembled team of climate experts [8] convene with other leaders to ramp up ambition and align action ahead of the COP. In light of many other nations committing to a green transition, will we see unity and global solidarity like we saw in Paris? Backed by green technologies and corporate ambition, will world leaders take bolder action?

Come 21 February, the Working Group will announce an interim SSC, SCN, and SCM. Based on the Obama administration’s formula, the price per ton would now stand at $52. However, Trump officials reduced it to between $1 and $7 per ton. Economists believe that the Biden administration’s price might start at $125 per ton to better reflect latest climate science and market realities. [9] We can expect the price that Washington sets to impact analysts’ valuation of companies, which will be carefully watched by investors.

By 1 February, the Biden administration has promised additional executive actions to address the climate crisis. Subsequently, the $2 trillion climate package is expected to be passed. With so much optimism surrounding this, it remains to be seen if they will live up to expectations and deliver the action needed in our race towards a decarbonised future.


These series of events have instilled hope, inspiration, and ambition. The global pandemic has awakened the need for change, we are optimistic that the world will embark on an acceleration of climate action like never before.

Carbon Assessment – Shining a light on Scope 3 emissions

These emissions have typically been hidden from view, but are increasingly coming into the spotlight.

By Junying Lou

Increasingly, companies are starting to expand their focus on greenhouse gas emissions from their core operations under Scope 1 and 2 to also include greenhouse gas emissions from their value chain (Scope 3 emissions) to better manage climate-related risks and opportunities.


But what exactly are scope 3 emissions?

In short, Scope 3 emissions are everything other than emissions from companies’ direct operations and purchased energy.  This includes all indirect emissions from both upstream and downstream and can be classified into 15 different categories, as shown in the graph below.

Overview of GHG Protocol scopes and emissions across the value chain

Figure 1: 15 Categories of Scope 3 emissions (WRI & WBCSD, 2011).

Source: GHG Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard.


For most sectors, scope 3 emissions are far larger than scope 1 and 2 combined. The Carbon Disclosure Project’s (CDP) recent research shows that on average, companies’ supply chain emissions are 5.5 times greater than their scope 1 and 2 emissions (CDP, 2019).


Scope 3 calculation: a journey that has to start somewhere

Scope 3 measurement and management can be daunting for most companies because the data coverage is comprehensive while the data sources fall out of companies’ direct control. Collecting this data requires collaboration with companies’ value chain partners.  Paia typically advises companies to start by drafting a Scope 3 emission management plan to guide in screening the most material Scope 3 emissions, collecting relevant data and setting goals. Compared to Scope 1 and 2 emissions, the Scope 3 emissions quantification is more complex and uncertain and requires an iterative approach to refine data accuracy.


The next step: reducing scope 3 emissions

The end goal of knowing the full climate impact from across the value chain is to inform business decisions in what they purchase, produce and put into the market, and steer companies and their value chain to a sustainable direction.

Companies that have gained a robust understanding of their Scope 3 emissions can leverage different emission reduction approaches to minimise the climate impact in their value chain.

Best practices to reduce scope 3 emissions include implementing internal carbon pricing, extending product life span, procurement practices that prefer low carbon suppliers.  The table below shows carbon reduction approaches for each Scope 3 category, as recommended by the Science Based Targets initiative (SBTi).

Levers for reducing emissions by scope 3 category

Figure 2: Levers for reducing scope 3 emissions by category (Science Based Targets initiative et al., 2018)


So why should companies care about their Scope 3 emissions?


As more governments announce their plans to reach carbon neutrality, the risks associated with rapidly evolving energy and carbon regulations are mounting. For example, if a company sources carbon-intensive materials and products, the future energy and emission costs absorbed by suppliers can significantly increase the costs of goods paid by the company. For other companies that sell energy-intensive products, they may well expect more stringent energy efficiency regulations as well as negative consumer sentiment towards their products.

Additionally, companies may also face reputational and even litigation risks if they fail to understand the climate impacts in their value chain.


Where there is a risk, there is an opportunity. Through prudent Scope 3 emission management, companies stand to benefit from improved efficiency and substantial cost saving in their supply chain. CDP recently reported a total of US$19.3 billion annual supplier financial savings associated with actions to reduce carbon emissions (CDP, 2019).

Understanding scope 3 emissions also drives innovation along the value chain and helps companies build competitive advantages as the world decarbonises. Companies that can reap carbon reduction opportunities along the value chain and offer low-carbon solutions are more likely to enjoy an increased market share and enhanced customer loyalty in the resource-scarce future.


Closing thoughts

As countries and organisations look to build back better post-pandemic, many signs are pointing towards an increased focused on Scope 3 reporting. As many may be aware, 2020 saw a series of net-zero commitment announcements by countries and corporations. We can only expect that these commitments will trickle down along the value chain, impacting various companies.

Quantifying and managing Scope 3 emissions is challenging and we are here to help, contact us today to know more about Scope 3 emissions and how you can effectively measure and manage them.

Carbon management: a step by step guide

Using Apple Inc. as a case study

By Junying Lou


The world has witnessed a string of climate disasters in recent years. In the United States alone, there have already been 10 extreme weather events with losses more than $1 billion each in 2020 (NOAA, n.d). China is currently dealing with the worst flooding in more than 20 years that affected about 55 million people (He, 2020). Australia’s 2019-2020 bushfires have destroyed 2,000 homes and 11.2 million hectares, equivalent to nearly half the area of the United Kingdom (Green, 2020). The list could go on, there is no doubt that climate change has become more palpable for people around the world.

Climate scientists have confirmed that “human influence on the climate system is clear” and “warming of the climate system is unequivocal” (IPCC, 2014, p. 2). The urgency of climate actions has called for more effective carbon management from the public and private sectors.

Carbon management is about taking steps to measure and manage greenhouse gas (GHG) emissions within your organisation and extend the reduction of emissions across your supply chain (FDF, 2008, p.8).

What is in it for me as a business?

Saving the planet alone may not be a compelling enough reason for organisations to commit to carbon management. That is why it is important to highlight that carbon management does make a good business case in the following areas (Zhou, 2020, pp. 91-96):

  1. Cutting cost: carbon management will open up opportunities for organisations to identify cost-saving areas within and beyond its direct operations through improved energy and resource efficiency.
  2. Reducing regulatory risks: more and more countries are adopting ambitious climate targets which will translate to more stringent regulatory requirements for carbon emissions.
  3. Responding to stakeholders’ interest: increasingly stakeholders are showing interest in corporations’ effort to combat climate change.
  4. Improving competitiveness and promoting innovation: through the process to achieve ambitious carbon reduction targets, corporations will catalyse the transformation of operational practices and adoption of new technologies.

Getting started: setting up a management system

Setting up a management system for carbon management, which includes policies, processes, and frameworks will ensure the credibility of recorded data and results.

Just like any other strategic initiatives, it is imperative to obtain buy-in from the board and senior management. The leadership and oversight at the top level can help secure necessary financial and human resource for the effective implementation, evaluation, and continuous improvement of the organisation’s carbon management plan.

Cross-functional working teams from all levels of the organisation shall be formed with responsibilities clearly defined and allocated. Some common roles include collection, compilation, and reporting of emission data; management and monitoring of carbon reduction initiatives; and staff awareness and education. Other key internal processes, such as procedures to govern data quality, need to be put into place.

What are the key steps?

With support from a well-designed management system, an effective carbon management plan normally involves “measure- reduce- extend” (Cambridge Programme for Sustainability Leadership/Business in the Community, 2009, p. 4)

Step 1: Measurement

When it comes to management, we all heard about “what gets measured get managed”, and this is particularly true for carbon management. To develop an accurate baseline GHG inventory requires identification of emission sources and collection of activity data for conversion to emission data.

Before starting the actual measurement, organisations need to decide on a few things:

Standards to follow for the emission measuring purpose: the most commonly known standards to corporations are ISO 14064-1 and The GHG Protocol Corporate Accounting and Reporting Standard, but there are also other industry-specific standards available.

Organisational boundary: A corporation with a complex organisational structure, such as having multiple subsidiaries, joint ventures, associated companies, etc. needs to determine which parts of the businesses to be included. This largely depends on the approach it selects to consolidate GHG emissions: the equity share approach or the control approach (WBCSD/WRI, 2004, pp. 17-19).

  • Under the equity share approach, a corporation accounts for the share of GHG emissions from the operations according to its share of equity owned. This approach best reflects the risks and rewards a corporation is exposed to from a certain operation, but performance tracking of operations that it does not have control over can present challenges.
  • Under the control approach, a corporation accounts for 100% of the GHG emissions from the operations it has control over. The corporation needs to choose between either the operational control or financial control. While operational control is more compatible with government compliance programmes and more appropriate for performance tracking, this approach may not fully reflect the commercial reality of the reporting corporation.

Operational boundary:  The operational boundary (Scope 1, 2 and 3) is defined at the corporate level after the organisational boundary is decided, this step determines the scope of emissions to cover.

  • Scope 1 direct emissions are emissions from sources that owned or controlled by your corporation, including emissions from company-owned vehicles, boilers and furnaces, and emissions from chemical processes, etc.
  • Scope 2 indirect emissions are a special category of indirect emissions that are associated with the generation of electricity, heat, or steam that is purchased and used by the corporation.
  • Scope 3 indirect emissions are everything else, emissions that are a result of the activities of the corporation, including both upstream and downstream. Scope 3 is an optional reporting category, however, more companies are increasingly interested in measuring and managing their Scope 3 emissions. For example, Apple has been publishing its Scope 1, Scope 2, and Scope 3 carbon footprint in its environmental progress report.

Source: Apple’s Environmental Progress Report 2020

If it is your corporation’s first year in this journey, it means a lot of hard work that can be separated into the following oversimplified and broad categories:

  • identification of emission sources
  • collection of primary and secondary data including activity data and conversion factors
  • conversion to emission data
  • and compilation of all data to be reported at the corporate level

Step 2: Reduction

Once the baseline GHG inventory is set, it can be used to guide future actions. Organisations may also find it a golden opportunity to uncover emission hotspots during the measurement phase they wish to concentrate their reduction effort on.

The corporation may consider setting a carbon reduction target to demonstrate its commitment. The carbon reduction target can be absolute or intensity target. The latest development with target setting is the adoption of science-based target among leading companies. According to Science Based Targets initiative (SBTi), a science-based target is defined as targets “in line with what the latest climate science says is necessary to meet the goals of the Paris Agreement – to limit global warming to well-below 2°C above pre-industrial levels and pursue efforts to limit warming to 1.5°C.” (SBTi, n.d.)

It is also important to decide the boundary of your target. As a minimum, the target should be set for Scope 1 and Scope 2 emissions, but since for the majority of sectors, the largest portion of a company’s emissions is Scope 3 emissions (Labutong, 2018), many companies are looking beyond their core operations to set Scope 3 targets. Apple, for an instant, recently announced that it will be 100% carbon neutral for its supply chain and products by 2030. (Apple, 2020)

To achieve carbon reduction targets, a series of carbon reduction programmes shall be devised and implemented. It is worth noting that carbon reduction activities can range from free to very low costs, such as simple user behaviour change like switching off when not in use, to high costs, such as investment in energy efficiency equipment.

We use Apple as an example to explore the wide range of projects and programmes a corporation can consider for emission reduction purpose. The selective projects Apple implemented are discussed in the hierarchical order of carbon management, which is first to avoid or reduce emissions through conservation and efficiency, then to eliminate emissions by switching to renewable sources of energy, and lastly to sequester or offset any residual emissions. (Second Nature, n.d.)

  • Avoid and Reduce

With an understanding of where the company’s biggest climate impact occurs, Apple prioritises low-carbon design of its products, at both manufacturing and product-use stages. The improved manufacturing processes that led to higher material efficiency, combined with the use of low-carbon materials like recycled materials, have reduced carbon emissions associated with Apple’s products, for example, it is reported that a 63% decrease in Apple’s aluminium carbon footprint is achieved compared to 2015.

Energy efficiency in Apple’s buildings is another focus area. It is reported that energy efficiency audits of buildings were conducted to identify system improvement opportunities, followed by energy efficiency measures. Apple estimates that its energy efficiency programme along with new building design can save about 7,500 metric tons of CO2e per year.

Apple’s At Home Advisor programme allows AppleCare customer service employees to work from their homes, and this single programme avoided nearly 22,000 metric tons of CO2e emissions in the fiscal year 2019. For other employees, Apple introduced a bus commute programme to reduce the use of single-occupancy vehicles and offer campus bicycles which resulted in an over 6,000 metric tons reduction in the fiscal year 2019.

  • Substitute

According to Apple’s report, it has generated or sourced 100% renewable electricity for its global facilities since 2018. The was achieved through Apple’s renewable energy programme, which took a blended approach that involves owning or investment in onsite and offsite renewable projects, entering into power purchase agreements, and purchasing market RECs. Since renewable energy has been the sole source of Apple’s electricity, its Scope 2 emissions were reduced to zero.

  • Offset

Apple reported that starting from April 2020, it has realised carbon neutrality for corporate emissions, which include not only Scope 1 and Scope 2 emissions, but also part of Scope 3 emissions, such as business travel and employee commute. In the same report, Apple reported a total of 50,540 metric tons of CO2e for Scope 1 emissions and another 520,160 metric tons for business travel and employee commute, so how could Apple claim carbon neutrality while still generating emissions from these sources?

apple greenhouse gas emissionsSource: Apple’s Environmental Progress Report 2020

The reality is that some emissions are difficult to avoid or reduce, so the last resort is to sequester or offset any remaining emissions through sequestration opportunities, Apple, for example, has been investing in projects that protect and restore forests, wetlands and grasslands that have removed enough carbon dioxide to offset the residual corporate emissions. For most organisations, it may be challenging to be directly involved in these types of projects, however, companies can still take advantage of high-quality and robust carbon credits to offset emissions.

Step 3: Extension

The last step and probably the most difficult one is to extend carbon management across its supply chain, but it is also a critical step if a corporation wishes to manage its Scope 3 emissions. To successfully cascade the strategy down to your suppliers, you need to work with your suppliers by prioritising suppliers to engage with and craft a communication plan to initiate and follow up with them, and ultimately it is about incorporating the carbon management criteria into the procurement process (Cambridge Programme for Sustainability Leadership/Business in the Community, 2009, pp. 41-44)

In Apple’s case, as 76% of its overall emissions come from product manufacturing which usually takes place in its suppliers’ facilities, Apple has been working with its suppliers through Supplier Energy Efficiency Program that aims to educate suppliers and help identify initiatives to reduce energy use and manage the implementation of the projects. Apple also supported suppliers’ reduction effort by providing funding for supplier projects, a special fund of $100 million was created for this purpose in 2019. Through Supplier Clean Energy Program, which aims to catalyse the adoption of 100% renewable electricity by its suppliers, Apple has been advocating its renewable energy policy and assisted the transition of its supplier through funding, training and other opportunities. So far, 71 manufacturing partners in 17 countries have committed to 100% renewable energy for Apple production.

Paris Agreement in Jeopardy? A Summary of CNA’s Carbon Conundrum

By Adrian Pang, Paia Consulting Pte Ltd

Channel News Asia’s documentary series earlier this month zoomed in on an impending disaster that is already set in motion – climate change or more accurately, anthropogenic climate change. The documentary explored the world’s profound reliance on carbon-intensive energy resources but highlighted some progress made in moving away from the self-destructing carbon addiction to provide a glimmer of hope of what could and should be done in the limited time to restore nature’s equilibrium. In the process, the documentary took mainly a Singapore-centric view complemented by international events and perspectives on the dire consequences of climate change and on finding solutions.

This piece provides a summary of the key messages conveyed by the documentary. The content follows the narrative of the documentary. First, it highlights the root cause of climate change: our addiction to fossil fuels that resulted in the dire situation and consequences regarding carbon emissions the world finds itself in. The next part of the summary presents provides a more optimistic outlook to the future with the developments of potential solutions in renewable energies as well as the simple yet complicated gesture to give agency back to nature to recover. First, the documentary reiterated the existence of potential solutions in the form of solar energy and green hydrogen. In Singapore, these potential solutions are undergoing consistent and significant development and testing. Thus, the most pressing issues is not about finding solutions but rather our willingness – government and corporations’ willingness to invest in these long-term solutions. Then, the documentary highlighted the abilities and importance of nature to regenerate itself and for us humans to coexist harmoniously with, if not live by laws of nature. The piece concludes on a note of caution that now is the time the world should drastically cut carbon emissions before climate change escalates to a point of no return very soon.

Carbon Junkies and the Consequences

Sequestered carbon from millennia of natural lifecycles of living beings that were formed into fossil fuels (coals, oil, natural gas, etc.) was always a natural process and fossil fuels were meant to be stored deep underground. However, this process was disrupted ever since the industrial revolution ushered in a new age of human progress that sees the stripping of Mother Nature’s resources as key to societal development. Human’s unquenchable thirst for fossil fuels for energy is the quintessence of this problem. As humans continue to pride ourselves on the technological advancements made in the past couple of centuries, we are ironically and rather stubborn sticking with carbon-packed resources to power our technological innovations and ingenuities. We have never moved on from fossil fuels as our primary energy sources. In fact, we fell deeper into the addiction problem to keep economies of oil-producing countries and financial markets well-oiled (pun-intended). Earth’s atmosphere was meant to be the protection but humans decided it is in their best interests to burn fossil fuels in the name of progress, thereby causing untold stress to this planet’s immune system that reduces harmful greenhouse gases like carbon dioxide. And burn we did for close to 300 years. In the process, we re-released inconceivable amount of carbon dioxide into Earth’s atmosphere.

In November 2016, the global community seemingly put aside their differences and set the world on an era defining path that was unimaginable just decades ago. 189 countries, even the reclusive hermit kingdom of North Korea, ratified or acceded to the Paris Agreement to begin intense carbon reduction to keep global temperatures in the 21st century to well below 2 degree Celsius above pre-industrial levels as well as to limit the temperature increase even further to 1.5 degree Celsius. The world committed to embark on several grand steps towards this common mission. First, carbon emissions and temperature rise should peak by 2020. Then, emissions should be halved by 2030 and the world needs to be completely decarbonised by 2050. Alas, the world now finds itself slowly creeping back to square one as the euphoria waned. The 1.5-degree Celsius targets based on current data are unreachable. Carbon emissions worldwide continue to rise. Countries’ support for this once hopeful – an understatement, milestone that showcased the best of humanity are being challenged at its core as individual economic interests supersede what needs to be done. The dwindling commitment is further exacerbated by the withdrawal of the United States, the biggest economy and biggest emitter in the world. Worst, the Trump administration ramped up fossil fuel production for their national economic interests. Ultimately, the world continues to find itself losing time faltering on significant efforts to protect and save itself from the dire consequences of climate change.

While climate change does indeed spare no-one, smaller nations, especially island nations are already bearing the full brunt of human’s inactions. The documentary went to Tuvalu, one of the smallest nations in the world located in the South Pacific between Hawaii and Australia. It showcased the plights of the country sinking fast beneath the sea to highlight the devastating effects of rising sea levels – the rate of which is faster in the past few decades than the last few thousands of years. When compared to more industrialised nations, all 57 small islands developing states (SIDS) including  (The Economist, 2019). [1] Yet, these countries are on the forefront of the consequences caused largely by their much larger and mightier industrialised counterparts. In the case of Tuvalu, their commendable efforts to slow their home from sinking through various adaptation mechanisms are increasingly futile. The country’s prime minister even gave grave warnings that climate change adaptation and resilience are no longer viable for his county and other SIDS. The documentary then revealed coastal and archipelago nations are the next in line to suffer the consequences of climate change. For example, 2,000 Indonesian islands and 20% of Bangladesh would be submerged under water by 2030. It will not be long before New York City and Amsterdam – great industrialised cities would sink beneath the waves by 2100 if sea level rises 1.5m, as per the current pace of climate change.

Singapore will not be spared either. Singapore is on course to lose of land to rising sea levels at the current trajectory according to the documentary. This problem is further compounded by the emergence of the fast emerging arctic sea route from melting ice caps, in which the new trade route is 33% shorter than the current one that has for so long made Singapore one of the trade centres of the world. This imminent new trade route would threaten the displacement of Singapore as a global commercial and trading hub, reducing the country’s competitiveness and even relevance in the global economy in the not too distant future. Singapore’s government has pledged SGD 100 billion to increase the country’s resilience to rising sea levels. Raising tidal gates, dykes and reservoirs, building the new Changi airport terminal more than 5m above sea levels and polders to reclaim land below sea levels are some of the measures taken. Even so, the pace that sea level is rising, and climate change worsening is gradually prompting the conversation in Singapore to shift ns much like the aforementioned sentiments by Tuvalu’s prime minister.

Stemming the Tide through Long-Term Solutions

The best solutions are none other than those that address the issue at its core, reducing carbon emissions within its own shores while hoping the rest of the world continue to play their parts. While existing steps to reduce carbon emissions would incur significant costs in the near future, the potential long-term impacts and values far outweigh the initial costs. short, the climate driven sphere has the highest job and business opportunities while the current linear economic business models destroy value and will slowly but surely be phased out. However, the pace of it happening is still a key factor in preserving the sanctity of Mother Nature and the climate. In view of these potentials while being mindful of the limited time before climate change is worsened beyond reparation, Singapore is taking bold but necessary steps to address the climate risks dawning upon our home. The main solutions covered by the documentary focus predominantly on technological innovations and Mother Nature herself.

i. Transition to Renewable Energies: Solar Power and Green Hydrogen in Focus

The most direct and logical steps to reduce carbon emissions is to generate electricity and energy through low carbon renewables. In short, reduce or even eliminate fossil fuels from the energy equation. This is the most obvious way forward because technologies are already in place and have proven capacities to replace fossil fuels as the biggest energy generator. . This technology will only get better with more investments and refinements in the future. Several innovations in Singapore can attest to the immense potential of the PV systems and the even higher ceiling of what this technology can achieve.

a. Building Integrated Photovoltaic (BIPV) Systems

Source: (SERIS, n.d.)

In a building design and architectural sphere, the Solar Energy Research Institute of Singapore (SERIS) and the School of Design and Environment at the National University of Singapore (NUS) have jointly designed, built, and are managing, refining and improving on the concept of BIPV where solar panels are fitted to the façade of a building to achieve the higher generation of solar generated electricity to become an energy self-sufficient and zero carbon emitting infrastructure. So unlike solar panels that are placed on rooftops, the solar panels are integral to the infrastructure, for example as and facades. Moreover, additional electricity generated can be fed back to the major electricity grid or be stored in battery for future use. SERIS stated that there are some 160,000 buildings that have the capacity to install sizeable BIPV systems far larger than the current testbed. In short, there is huge potential and benefits if Singapore decides to venture down this path.

b. Floating PV Systems

Elsewhere, the government’s Economic Development Board (EDB) and the Public Utilities Board (PUB) have also collaborated on taking PV systems to the next level. The collaboration aims to evaluate the performance of different solar systems and their impacts on the environment. As a result, the joint venture has produced largest floating solar panels testbed with 10PV systems across 1 hectare on water currently in the world according to the documentary. In fact, this trial has generated better results than expected as it was found that the cooling nature of water enables the PV to be more efficient. The floating PV systems generated 5% to 15% higher electricity than typical rooftop systems as well as possessing capacities to power 200-odd 4-rooms HDB flats per year, all the while having minimal environmental impacts. With such positive outcomes from the testbed, both EDB and PUB have targeted to introduce floating solar projects in the Bedok reservoir and Lower Seletar reservoir by mid-2020. Furthermore, the joint venture wants to introduce even larger scale floating PV systems 50 times the size and capacity of the existing testbed that can generate 6,000 MWh of electricity by 2021. This target is set with the goal of ramping up 2-Gigawatt Peak solar capacity that can power 350,000 households or 4% of total electricity demand in Singapore daily by 2030.

c. Commercial Leadership & Intergovernmental Cooperation

Sunseap Group, one of the largest renewables and solar energy companies in Singapore has also aggressively attempt to push and drive Singapore and Southeast Asia to adopt renewable solar energy to generate electricity. The documentary highlighted Sunseap’s success story in the Ninh Thuan province in Vietnam on the positive environmental as well as social and economic impacts of solar PV systems. Sunseap Group has installed 449,880 PV modules in the province that can generate 20 million kWh of electricity to power 100,000 households every month. This is a significant development for one of the least developed regions in the country. The establishment of the PV farm has created positive social impacts such as providing better infrastructure and paved new roads for the local communities to connect with the urban and peri-urban areas. Economically, this project has created new jobs for the community. 2,000 employees were hired for the construction of the farms and 35 permanent positions were created after construction completion. This is one of many indications of Sunseap’s ability to be a leading figure in the development of the renewable energy sector in Southeast Asia or ASEAN region. As per Frank Phuan, CEO of Sunseap Group, he used the examples of the infrastructures in place in Malaysia and Singapore to upscale PV systems between the Johor Straits to accentuate on the fact that it is political will – whether ASEAN countries are willing to cooperate in this sphere to create a shared “ASEAN power grid” that balances countries with in the region with rich renewable energy resources against parts of the region that have high energy demands, that would determines the growth of renewables in this region. He added that the technicalities are no longer a barrier to prevent ASEAN countries from taking a huge leap towards transitioning to renewable energy.

d. Green Hydrogen

Amongst the more popular renewable energy sources like wind and solar, one source, one element has been under the radar and perhaps in the shadow of the former two counterparts – hydrogen. As the most abundant element in the whole of the universe, hydrogen also possesses the potential to become a clean and efficient alternative to fossil fuels. The only complication from venturing headfirst into using hydrogen as fuel source is its highly combustible nature. Moreover, the storage of hydrogen in conventional high-pressure tanks is not the most logistically and environmentally efficient manner to attain hydrogen if we consider the transportation of these heavy tanks. Fortunately, the Tohoku University in Japan is developing a new technology in the form of metal hydrides. Metal hydrides are metals which have been bonded to hydrogen to form a new compound. This compound, at the current stage of research and development are pointing towards the elimination of the conventional method of storing hydrogen in high-pressure tanks as it exists in metallic powder forms. But more research is required as the process of retrieving energy from the powdered metal hydrides requires high energy itself to heat and activate the compound.

Back in Singapore, a more basic form of metal hydrides system is undergoing testing. The testbed is also showing positive results. Instead of storing metal hydrides in powdered form, hydrogen is stored in a metal hydride tank using the same concept of binding hydrogen with metals. When electricity is needed, hydrogen is released from the tank and passed through fuel cells. Prior to storage, hydrogen is attained by breaking down water in a separate compartment in the testbed. Overall, the energy required for the entire generation process, from breaking down water to releasing hydrogen from the metal hydride tank only used electricity generated by solar panels. As a result, the Singapore Power Training Institute is the first zero emission building that is powered fully off the grid by green hydrogen in ASEAN region.

ii. Restoring Nature

It is undeniable that the ongoing coronavirus pandemic is grim and disruptive on all fronts. However, environmental lessons while secondary to public health, can be taken from this challenging time. The pandemic shows Mother Nature’s ability to regenerate herself over the short period of time when human activities almost came to a virtual standstill. Air pollution levels decreased quite significantly, rivers became clean and clear again and the air fresher. This is an indication that humans do not actually need to take draconian measures to make changes possible. Rather we can take modest but nonetheless significant steps to eventually phase out things that are environmental detrimental like excessive carbon while allowing the Earth to heal. Nature has a strong will and has shown time and again its ability to restore itself – think Chernobyl and the nature that reclaimed the abandoned city in just a few decades. Therefore, the message from the documentary is to give agency back to nature to do what it does best, to recover and regenerate itself. In particular, restoring plants and their habitats should be a priority in major efforts to help nature to recover because plants are nature’s front liners against rising carbon dioxide level. The documentary focuses on mangrove trees as exceptional carbon scrubbers. This plant species can sequester 3 to 5 times as much carbon as land-based jungles. Thus, experts are studying closely on ways to preserve, conserve and cultivate new habitats in historically alien environments in other parts of the world. Even so, the bottom line remains – preserve and plant more trees.

In so doing, nature’s recovery and flourishment will only further benefit human’s health. It is scientifically proven that the human biology is wired to sync harmoniously with nature. The practice of shinrin-yoku or forest bath in Japan shows how human’s immersion in nature can have healing effects on the mind and body. Therefore, it is a ‘kill two birds with one stone” scenario whereby a thriving nature benefit both humans and Earth. Shifting the focus back to Singapore, it is unsurprising that this belief in nature’s healing abilities has led to the restoration of freshwater wetland in Singapore’s Botanical garden. As a result, it not only restores habitats but also act as a potential water reservoir that redirects flood water from urban areas to the area to make this city state more flood resilient. In summary, we should strive to let nature reclaim its equilibrium and us humans should coexist peacefully with, if not live harmoniously in nature.

No Time for Caution and Complacency

Climate scientist assistant professor Angel Hsu of the Yale-NUS College summarised best the reason climate change is described as the “super-wicked problem”. One, time is running out and relatively little has been achieved. Next, many people currently entrusted to solve climate change are ironically people who are causing it due to their other interests and their questionable practices in the process, best demonstrated by how these people fly extensively to attend meetings to combat climate change. Third, there is no central authority in the fight against climate change. As a result, every country prioritises their own interests before the common necessity to fix the climate and environment. Finally, and most damning of all, the persisting paradigm that climate change is a problem for the future. In reality, there is no time for caution and complacency. Carbon dioxide must begin declining this year or the world risks an irreversible disaster. Systemic changes are needed where business leaders and governments pool together resources and expertise to deal with this common enemy. We are one species after all.

While Singapore has taken good strides to address climate change issues at home, we need to be conscious that there are still other areas that could be done better. For example, the country could accelerate the transformation of public transportation system. Electrifying public buses and increasing bicycle lanes should be fairly easy to be implemented in an enclosed and well organised country like Singapore. Shenzhen, which is roughly the same economic size as Singapore has electrified all their public buses in 5 years, Singapore can surely do better than setting this target to be achieved by 2040 (He, 2018). Therefore, we are only at the prelude of the fight against climate change and the climax will arrive quicker than ever. If we do not take significant actions, the crescendo [2] of the disaster will likely drown out any hopeful progress. And climate disaster will happen more as a caesura [3] to the end of human existence than a diminuendo [4] like most lifecycles.
