COP29 approves new UN rules on global carbon credit trading

Governments at the COP29 talks approved new UN standards for international carbon markets in a key step toward allowing countries to trade credits to meet their climate targets.

At the UN climate talks in Azerbaijan on Monday, nearly 200 nations agreed on crucial ground rules for setting a market in motion, but further negotiation is needed before the overall framework is finalised.

US president-elect Trump has said he would again pull the US out of the global Paris climate agreement, which lays the groundwork for the planned UN-backed carbon market.

However, Juan Carlos Arredondo Brun, a former climate negotiator for Mexico who now works for carbon market data and souring company Abatable, said the endorsement "will bring us closer to operationalising the carbon market before any single party may decide to move away from the Paris Agreement".

Monday's deal could allow a UN-backed global carbon market, which has been years in the making, to start up as soon as next year, one negotiator said.

Carbon credits theoretically allow countries or companies to pay for projects anywhere on the planet that reduce CO2 emissions or remove it from the atmosphere and use credits generated by those projects to offset their emissions.

Examples of projects could include the cultivation of CO2-absorbing mangroves or the distribution of clean stoves to replace polluting methods of cooking in poor rural communities.

The market could be one route for US companies to keep participating in global efforts to address climate change, even if Trump were to quit the Paris accord. If that happened, US firms could still buy credits from the UN-backed market to meet their voluntary climate targets.

While the standards approved in Baku were aimed at allaying concerns that many projects do not deliver the climate benefits they claim, campaigners said they fell short in areas including protecting the human rights of communities affected by projects.

Strong standard

"A lot of funders are worried that the markets aren't stable enough, credible enough to be able to invest more in," Rebecca Iwerks, a co-director at non-profit group Namati told Reuters.

"It could actually hinder the development of the market if you don't have a strong standard," she said, of Monday's deal.

Some negotiators were also critical of the way the deal was done. The standards were agreed by a small group of technical experts, with some countries saying they had not been given a fair say in the final rules.

Kevin Conrad, executive director for the Coalition for Rainforest Nations and former climate envoy for Papua New Guinea said the supervisory board had overstepped its mandate.

"We endorse what they have done, not the way they have done it," he said.

Countries at COP29 will also try to finish other rules aimed at creating a robust market.

The International Emissions Trading Association, a business group that backs global carbon markets, has said total trading in the UN-backed market could by 2030 generate $250 billion a year and cut 5 billion metric tonnes of carbon output annually.
