Understanding Voluntary Carbon Markets

Carbon Finance

With the UN Climate Change Conference now settling into the rearview mirror, stakeholders questioned Nov. 23 how carbon dioxide removal can be done with climate justice concerns in mind.

"The decisions that were made at COP do provide momentum to CDR," said Hunter Cutting, communications director of Climate Nexus, during a panel discussion. "There's a growing social license to CDR and this COP helped push that along, like it or not. I think the question increasingly becomes, how is it done responsibly?"

Janos Pasztor of the Carnegie Climate Governance Initiative cited a lack of formal discussions about climate justice issues at COP26, held in Glasgow.

"So there's a big gap that needs to be met somehow, and we haven't yet met that in COP26," Pasztor said.

Article 6 of the 2015 Paris Agreement, the provision that determines how countries can reduce emissions through carbon credit trading, was a primary focus of COP26. In the final hours of the conference, long-awaited agreements were made on a set of rules that govern international carbon markets.

One key agreement at COP26 aims to avoid double-counting credits that are traded across borders by creating a verification system under the UN that ensures one credit counts towards one country's national determined contribution, then is removed from the country's emission accounting if it is sold.

This agreement, among others, generated speculation that the firmed-up rules would open the door to billions of dollars of investment in the carbon markets over the next several years. And market prices of emission offset credits are already reflecting the growing demand for these credits among companies with net-zero commitments.

According to Platts price assessments, CORSICA-eligible carbon credits have surged by nearly 20% since the first day of the conference, to $17.55/mt CO2e on Nov. 22 from $14.70/mt CO2e on Oct. 31. Nature-based carbon credit prices have grown to $13.95/mt CO2e from $9.65/mt CO2e over the same period, a 45% gain.

The collateral effects of a scaled-up carbon market could be multifold. Cutting fears that skyrocketing demand for offsets could spark a land rush in developing countries as large emitting companies look to buy up nature-based carbon credits to meet their net-zero commitments. And there are concerns of over-reliance of offset credits that allow companies to continue emitting, thereby exacerbating localized pollution that could have community-level impacts.

"This speaks to the question that many have rightly raised: Is CDR being used in place of emission reductions that should be done?" Cutting said. "I think these are the question that rise quickly to the top in the wake of this COP."

COP26's anointment of CDR as a primary market-based solution to fighting climate change may signal a new era in the discourse surrounding carbon capture and carbon credits. The panelists, hosted by the Institute for Carbon Removal Law and Policy at Northwestern University, questioned whether it's time to push beyond net-zero commitments and into an era of net-negative commitments, the panelists said.

Nature-Based Credits

In 2005, when Louisa and Michael Kiely began talking to farmers about soil carbon in New South Wales in Australia, they were met with incredulity.

More than 20 years later, Carbon Farmers of Australia—the advisory they founded—has licensed projects spanning 750,000 hectares with a 3,700 sq km project in South Australia.

"We persevered and are now dealing in Paris Agreement-compliant credits," Louisa said. "Things have changed. Carbon trading now has a gold-rush feel to it."

In a landmark deal earlier this year, Australian-owned Wilmot Cattle Co. announced the sale of $500,000 worth of soil carbon credits to Microsoft, which has pledged to become carbon negative by 2030.

Soil carbon sequestration involves removing carbon from the atmosphere and storing it in soil. The process relies primarily on land management practices like preventing overgrazing and tilling, better water management practices and composting.

A number of factors, however, impede the popularity of soil carbon as a credit. And compared to the soaring popularity of forestry and household credits, it's hard to find registered soil carbon credits on popular standards like Verra and Gold Standard.



State policy

Climate change policy has played a huge part in Australian elections and domestic policy over the last 15 years. The Carbon Farming Initiative Act 2011 encouraged Australian farmers to earn credits by changing land use practices to store carbon and reduce greenhouse gas emissions. The Australian government invested $9.6 million in its Soil Carbon Research Programme that concluded in 2012.

In 2011, the Gillard administration passed the Clean Energy Act through which a carbon pricing mechanism came into effect. This was repealed in 2014 by the Abbott administration, which introduced the voluntary Emissions Reduction Fund in its place. A large part of the trading under the ERF comprises soil carbon credits. The Morrison administration, in its 2021–22 budget, promised to deliver $233.6 million in new funding to improve and protect Australia's soil.

APAC Markets

China's national carbon market started trading on July 16 with the first CO2 trade done at Yuan 52.80/mt ($8.20/mt), a relatively low carbon price compared with regulated markets in the US and Europe.

The highly anticipated launch of China's carbon market paves the way for the decarbonization of its industries, starting from the power sector, and will help meet the country's long-term 2060 carbon neutrality goals.

Initial carbon prices, however, were relatively low due to a generous allocation of allowances in an effort to familiarize the industry with carbon pricing. Going forward, allowances are expected to be tightened as China's carbon policy takes shape and after cost-effective abatement technologies are developed.

The first online transaction of China's Carbon Emission Allowances, or CEAs, was priced at Yuan 52.80/mt ($8.20/mt) and the transacted volume was 160,000 mt of CO2 at 9:30 am July 16, according to state broadcaster China Central Television's Weibo social media account.

China's nationwide carbon trading officially started at the Shanghai Environment & Energy Exchange on July 16, and the first transaction was done immediately after the official launch, according to CCTV.

"Shanghai Environment; Energy Exchange now manages the online trading. How the other pilot exchanges will participate; depending on the government's further announcements," the spokeswoman for Beijing Environmental Exchange, one of the pilot exchanges for China's carbon trading, said.

In comparison to the Chinese market's initial $8.20/mt CO2 price, European carbon prices were around $61.92/mt on July 15, while California's cap-and-trade prices were at $24.30/mt at the end of last week.

In voluntary markets, the S&P Global Platts CORSIA-Eligible Carbon Credits was assessed at $3.05/mtCO2e on July 15, while Platts Nature-Based Projects Carbon Credits and Platts Household Devices Carbon Credits were assessed at $4.79/mtCO2e and $6.17/mtCO2e, respectively.

The participating power companies collectively account for over 4 billion mt of CO2 emissions, according to the environment ministry. The European Union ETS has around 1.6 billion mt of circulating allowances, according to European Commission's official website.

European Reform

The European Commission is gearing up to target CO2 emissions from the transport sector as part of its plans to cut greenhouse gas output by 55% below 1990 levels by 2030.

The EU's executive arm is set to unveil a standalone carbon market for the road transport sector that will target upstream fuel providers, according to draft documents leaked in late June.

U.S. Activity

On the same day that North Carolina regulators advanced a proposal to include the first Southern state in the Regional Greenhouse Gas Initiative, a similar and highly contentious plan in Pennsylvania cleared a critical threshold.

The Pennsylvania Environmental Quality Board voted 15-4 in favor of advancing Democratic Gov. Tom Wolf's signature climate initiative on June 13, despite fervent efforts by Republican legislators to keep their state out of the expanding cap-and-trade market.
