SINGAPORE — The vision is grand, the outcome could be just what the planet needs: investing billions of dollars to save vanishing nature and fight climate change at the same time.
The foundations of such a market already exist. Called the voluntary carbon market, it focuses on the ability of nature to soak up huge amounts of planet-warming CO₂. Developers of conservation projects earn a return by selling carbon credits to buyers, usually big companies, to help them meet their climate goals.
Essentially, you are offsetting a portion of your own carbon emissions by paying someone else to do it for you.
The market, though still small, has shown it works. Scores of successful nature-based climate projects exist which avoid or lock away millions of tonnes of CO₂.
Now, faced with the twin emergencies of climate change and biodiversity loss, investors want to remodel the market and channel huge sums into protecting and rehabilitating rainforests, mangroves and grasslands, and greatly expand the volumes of carbon credits, or offsets, for sale.
By the end of the decade, the market could be worth billions of dollars a year and Singapore is aiming to be a regional carbon credit investment and trading hub.
Efforts are well under way in Singapore and around the globe to make the market more transparent, more efficient and improve the quality and verification of the nature-based climate projects to entice large-scale investment. If done well, it could be a win for the fight against climate change and curb the loss of nature.
Trust and transparency
To get there, the market must overcome questions about transparency and concerns over ensuring every project does what it claims: reduces or locks away CO₂ in a fully verifiable way.
And investors also need reassurance that the conservation or replanting projects are fully protected and not destroyed by fire or cleared for agriculture or logging. That's where technology such as satellite monitoring comes in.
While existing projects have proved the model, the concern is whether vastly scaled-up investment will undermine the integrity of the market in the rush for carbon gold.
Carbon credits represent a tonne of CO₂ reduced or locked away. It’s an attractive idea for customers such as car manufacturers, tech firms, banks and pension funds keen to hedge their future carbon costs.
A key focus, particularly in Southeast Asia, is on saving natural ecosystems rich in carbon and with a high capacity for soaking up CO₂, such as peat swamp forests. These forests and replanted areas need to be protected over the long term from logging, illegal clearing for palm oil and fires. Which is why well-run projects hire staff to monitor the project area on the ground, and in space using satellites.
Ultimately, the idea is about putting a value on ecosystems, a value that helps them compete with mining, industrial agriculture and logging interests.
The higher the carbon price, the greater the return — and the incentive for investors to take the risk.
The Singapore connection
“Thanks to their rich forest, wetland and mangrove ecosystems, South-east Asia and Asia generally are set to become one of the largest suppliers of natural climate solutions (NCS) globally. The region houses a third of the cost-effective NCS supply potential from both the protection and restoration of natural ecosystems in countries like Indonesia, Malaysia and India,” said Mikkel Larsen, chief sustainability officer for DBS Bank.
That makes Singapore a natural centre for investing in these projects and trading the credits — this explains why Temasek, DBS and others are looking at ways for Singapore to capitalize on revamping the market.
The idea is to leverage Singapore’s long history in commodities trading and its well-regulated financial market. Singapore firms could use offsets as part of their emissions reduction strategies and, one day, carbon credits might be included in the nation's carbon tax scheme.
Temasek has been helping to guide Singapore’s evolution into a carbon services hub and has bought offsets from two forest carbon projects to meet its internal emissions targets.
A Temasek spokesman said multiple approaches should be used in the fight against climate change, including carbon offsets. He added that Temasek hopes to support natural climate solutions and carbon projects that are of high quality and meet other social and environmental aspects, such as conserving and restoring important ecological systems like peatlands, rainforests and mangroves.
Preserving and rehabilitating these areas also reduce the risk of fires and haze, and are good for local communities.
Investor interest is being driven by mounting pressure on companies and governments to meet stringent climate targets. Globally there’s been a surge in pledges to reach net-zero emissions by mid-century. To get there, you’re going to need nature.
“Eliminating the 51 billion tonnes of greenhouse gases added to the atmosphere every year requires an enormous amount of global momentum and investment,” said Dharsono Hartono, co-founder of the Katingan-Mentaya forest preservation project in Central Kalimantan on Borneo island.
“This is going to involve entirely rethinking how we produce energy, how we travel and how societies operate. But it also means rethinking how we treat nature. To keep global warming well below 2°C., we must protect nature,” he added.
The Katingan-Mentaya project, comprising mostly carbon-rich deep peat swamp forest, is about twice the area of Singapore. Saving it from destruction by palm oil companies means about 7.5 million tonnes of CO₂ are prevented from being emitted every year. Selling carbon offsets to big corporations, including VW Group, Shell (RDS.A) and Bank of America (BAC), helps run the project and fund community programs.
Dharsono’s project, though, represents a fraction of the true potential if huge investment is channelled into well-managed and well-funded projects.
South Pole, a Swiss firm that has developed more than 800 carbon offset projects globally, sees big opportunities for investment.
“Nature-based solutions — such as forest protection and restoration — can actually provide over a third of the climate mitigation needed between now and 2030 to stabilize warming to below 2°C. very cost-effectively. So investing in a cost-effective solution that can mitigate over 30% of global greenhouse gas emissions seems like a no-brainer,” said Leah Wieczorek, South Pole’s business development lead for Asia, who is based in Singapore.
Under the 2015 Paris Climate Agreement, nearly 200 nations agreed to limit global warming to less than 2°C., and aim for 1.5°C., above pre-industrial levels if possible.
Prof. Koh Lian Pin runs the Centre for Nature-Based Climate Solutions at the National University of Singapore. He and his team have analyzed areas of the planet that could yield good returns for investors.
In a recent study published in Nature Communications, Koh and colleagues show that at an initial carbon price of US$5.80 (S$7.70) a tonne, the protection of tropical forests can generate investible carbon amounting to 1.8 billion tonnes a year globally — roughly the annual emissions of Japan and Australia combined.
Financially viable carbon projects could generate return-on-investment totaling $46 billion a year, with the highest returns in the Asia-Pacific at $24.6 billion, followed by the Americas and Africa.
And the higher the carbon price, the greater the area of forest carbon sites that could be conserved.
The recent surge in interest in carbon offsets is pointing to higher prices, especially buyers locking in future flows of offsets at higher prices for high-quality projects.
Groups such as former Bank of England Gov. Mark Carney’s task force on scaling up the voluntary carbon market foresee exponential growth over the coming decade.
“In 2019, just over $300 million worth of trading took place on the voluntary market when these projects should be measured in the tens of billions of dollars per year,” he told a green finance summit in London last November.
Investors such as HSBC and Australia’s Pollination group, a climate change advisory firm, agree.
Last year, both teamed up with the aim of creating the world’s largest dedicated natural capital asset management company. They are launching a natural capital fund to invest primarily in regenerative agriculture and sustainable forestry projects. A second carbon fund is also planned aiming to ramp up investment in carbon offset projects. Overall, the intention is to raise up to $6 billion in funds.
“We take the view that there is a huge amount of demand and very little supply such that investment is required in the underlying projects to scale them up rapidly,” said Martijn Wilder, Pollination’s founding partner.
The funding model for nature-based projects has to change, he said, with significant upfront funding crucial to ensure projects get off the ground, are well managed and well protected.
“Protecting a rainforest is an infrastructure project. That’s what you’re doing.”
HSBC said escalating risks to the climate and biodiversity have changed mindsets.
“Today, nature is undervalued and overlooked by our investment community. This must change,” said Melissa McDonald, the bank’s global head of responsible investment.
How to scale up
The existing voluntary carbon market has been around for about two decades and has strict standards for offset projects. But trading has always been small and opaque because it’s purely between buyer and seller and not on an open exchange. That needs to change, market players said.
The main standard-setting body that certifies offset projects, Washington-based Verra, has issued offsets representing 622 million tonnes of CO₂ reduced from 1,697 projects to date. That’s the equivalent of taking 132 million cars off the road for a year.
And the market is growing. “We’ve seen that in terms of the volumes of the projects coming through the door. That’s definitely growing. We’ve seen in the past few years an increasing trend towards natural climate solutions,” said Verra CEO David Antonioli.
South Pole’s Wieczorek said interest is growing in Asia, too. “We are seeing a dramatic increase in clients in Asia looking to make carbon reduction commitments,” she noted, adding that some clients are looking to lock in long-term offtake contracts.
“The vast majority of humankind’s carbon emissions are currently unpriced, so having a dedicated budget for offsetting also helps companies set or at least consider an internal price on carbon,” she added.
For now, though, Carney, who is the United Nations special envoy for climate action and finance, said the voluntary carbon market still struggles with low liquidity and scarce financing.
To scale things up, Koh said, the market must overcome pain points. “The market will grow with our ability to improve the quality of those nature-based credits, our ability to reduce the cost of validation, of certification, to improve the transparency of monitoring those projects.”
Larsen, of DBS, agrees.
“The thing that has plagued the voluntary carbon market for the longest time is issues around trust and integrity. The quality and integrity of the projects is believed to be too low,” he said. People buy a project and it doesn’t do what it is said to do, that’s the integrity. Or it creates problems and social issues, that’s the quality, he said.
“There’s no doubt that carbon offsets projects, if done right, do work, and they do sequester carbon,” he said. But he also feels that transparency around pricing and verification is needed. Technology can help by improving the science and technology around projects, around verification of carbon stock, for example finding ways of improving carbon sequestration.
One firm that has brought price transparency is Singapore-based AirCarbon Exchange, a digital platform that trades fully verified carbon offsets. The exchange treats carbon offsets like a commodity with a range of offsets available for trading.
“The current market construct fails to send a strong price signal due to a fragmented project-based trading environment. A strong price signal will unleash pent-up capital to finance climate mitigating projects,” said Bill Pazos, AirCarbon’s chief operating officer and co-founder.
Few in the market question the integrity of the standards set by Verra — it’s more that the problems lie elsewhere in the market as it has evolved. “These standards have been around for 15 to 20 years. They are very robust. They are constantly evolving and improving themselves,” said Pollination’s Wilder.
Verra’s Antonioli said they are constantly updating their standards according to changes in technology, regulations and latest scientific evidence.
Some conservation groups say offsets are just a dodge, allowing polluters to buy their way out of making deep emission cuts to their operations.
That is untrue, key players said.
“It is impossible right now for most companies to achieve climate neutrality, a key milestone on the journey to meet net-zero pledges, without the use of carbon credits,” said Wieczorek.
Offsets from well-run, fully verified projects can help firms that are already cutting emissions go the last mile.
For Larsen, carbon credits are responding to an urgent need. “We talk about carbon offsets as a potential point of delay and inaction. And I always really struggle with that because with a football field of rainforest being cut down every six seconds, the inaction lies in not trying to help.”
Wilder said that for now, carbon financing remains a vital source of funding for conservation, despite the detractors. “The global climate is in crisis and we have to do everything we possibly can to reduce the risks. We shouldn’t be ideological about offsets and how we do it, provided the actions are real and have integrity.”
