Satellites: "actually..." - Methane destruction in the stratosphere is nearly double what climate models estimate, satellite observations show, according to a study published in the Proceedings of the National Academy of Sciences of the United States (PNAS). The study found stratospheric methane loss of 49.8 Mt per year - compared with 38.1 Mt/y from reanalysis and 25.7 Mt/y from chemistry-climate models. Researchers used satellite measurements of methane concentration, temperature, and radiative heating for 2007-10 to provide the first observationally based estimate of this critical methane sink. Substituting the observational estimate into the bottom-up global methane budget reduces the reported imbalance for the 2000s from 23 to 3 Mt/y, aligning it with the 5 Mt/y imbalance from top-down estimates. The findings could improve confidence in methane-climate assessments and understanding of global methane emissions, authors said.

International financial transfers may offer a more practical pathway to achieving global net zero than requiring developed countries to deliver additional large-scale carbon removal (CDR), according to new modelling.

Kenya's decision not to approve clean cookstove distributor Koko Networks' carbon project was unexpected for a company backed by the World Bank's political risk guarantee, which is specifically designed to prevent this kind of breakdown, according to experts.

A durable carbon removals (CDR) project developer on Thursday announced an offtake agreement with a carbon credit procurement company that involves 105,000 tonnes of CO2, destined for the aviation sector.

The Republic of the Congo seeks to improve its capacity as a net carbon sink some 47.8% by 2035 compared to business-as-usual levels, conditional upon international support such as carbon trading under Article 6 of the Paris Agreement.

The EU has an opportunity to help other countries build their own carbon pricing programmes, and forge alliances, as part of its strategy for buying Article 6 carbon credits – once the bloc has a clearer idea of how it wants to participate in global markets, according to the head of international emissions trading lobby IETA.

Climate action is "mission critical" to global security, the UN's climate chief said in a speech looking ahead to a particularly complicated annual climate summit in November, in the face of evermore hostile geopolitics and led by a first-of-its-kind shared presidency between Turkiye and Australia.

South Africa’s energy minister is working on a proposal to temporarily suspend the carbon tax in a bid to ease pressure from electricity tariffs, a move which could weaken climate policy signals and complicate access to Just Energy Transition Partnership (JETP) finance, according to local media reports.

Liberia last month provoked backlash when it announced it would create a compliance mechanism charging $25 per tonne of CO2 to maritime and aviation operators – but this mechanism has been misunderstood and will be revised to remove sensitivities, according to a top official.

A Seoul-headquartered trading company has secured what it claims to be creating the foundation for international transfer and sales of Paris-aligned carbon credits from its hydro power project in Indonesia.
