Rural cookstove projects are “likely highly additional”, especially in areas without other government incentives, according to a new study.

Carbon collaboration - Toronto-based Super6 Carbon, a developer of biogenic CDR projects, has signed a strategic agreement with Denver-based Mangrove Systems, a provider of digital MRV tools, to deploy its MRV platform across Super6’s engineered carbon removal network in the Midwestern US, the companies announced on Tuesday. The deal covers audit-ready tracking of biogenic CO2 from capture through transport and permanent geological storage, including Super6’s first transload hub being developed with Archer-Daniels-Midland Company in Decatur, adjacent to a permitted Class VI well.

The US EPA is expected to finalise a repeal of the 2009 endangerment finding this week, a move that would remove the legal foundation for federal regulation of GHG emissions, the Wall Street Journal reported on Tuesday.

A US-based project developer announced on Tuesday that forest carbon credits from two improved forest management (IFM) initiatives, tagged with the Core Carbon Principles (CPP) label, have achieved release and verification.

ZEV rebate set - Oregon's Department of Environmental Quality (DEQ) has established the funding limit for Class 3 vehicles - those weighing between 10,001 lbs (4,500 kg) and 14,000 lbs (6,400 kg) - under its ZERO Fleet programme that aims to support the purchase of zero-emissions medium- and heavy-duty vehicles. The funding cap for Class 3 rebates has been set at 12% of the total funding allotment, which comes to a little over $2 mln. Once this percentage is fully committed, new Class 3 rebate applications will no longer be accepted, DEQ said.

Mapping wildfire risks – US non-profit CarbonPlan announced on Tuesday it had launched Open Climate Risk, a fully open system providing building-level climate risk data for the US, starting with wildfires. The platform publishes inspectable wildfire risk datasets and modelling methods, and includes a public mapping tool that allows users to explore, download, and analyse risk estimates at scales ranging from state and county to census block, aimed at supporting climate adaptation decisions by policymakers, researchers, and communities. CarbonPlan noted that such data has often been proprietary and inaccessible to communities that need it the most.

A UK-based impact investment manager has made its first investment in Brazil to finance the initial phase of a carbon project under development in the Amazon rainforest, it announced on Monday.

International cooperation - Brazil joined the International Carbon Action Partnership (ICAP), the organisation announced on Monday. The membership followed a formal application by the Minister of Finance Fernando Haddad. Brazil will have access to a global network of jurisdictions committed to exchange expertise and enhance the effectiveness of emissions trading systems, while ICAP will engage with the open coalition launched by the country last year. With the new addition, ICAP has 36 members and nine observers.

Cross border carbon - More than 100 ranchers and landowners from northeastern Mexico and Texas met at Hacienda Yturria Ranch to discuss high-integrity carbon credit development through agricultural land management organised by Earth Carbon, Mexico Business News reported. The binational seminar covered Mexican states Tamaulipas, Nuevo Leon, and Coahuila, with presentations on measurement, reporting and verification systems from experts including Jim Blackburn of BCarbon and James Clement of Earth Optics. Mexico has more than 300 carbon credit projects operational or under development, said Marco Hernandez, CEO of carbon project developer Carbonof, adding the country's infrastructure and skilled workforce allow projects to meet US and European quality standards at competitive costs.

Biochar and other carbon removal (CDR) pathways delivered significantly fewer credits than forecast in 2025, according to a report released on Tuesday.

Browser neutral – The Canada-based browser developer Shift announced Tuesday that it offset 599 tonnes of CO2e generated by its community between July-Dec. 2025 via the launch of its in-browser Carbon Meter. The company said it purchased verified carbon credits through Carbonzero, supporting forest conservation in Canada’s Great Bear Rainforest and low-carbon cement projects in the US. The company added that it has tracked its Scope 1, 2, and 3 emissions since 2023 and worked with Carbonzero to offset corporate emissions in 2023 and 2024.

Congressional pushback – Democratic lawmakers have urged the US Court of Appeals for the District of Columbia Circuit to rule that the Trump administration unlawfully suspended nearly $20 bln in Biden-era climate grants, E&E News reports. They argued that the executive branch lacks authority to freeze congressionally appropriated funds. In a friend-of-the-court brief filed on Monday, eight senators and 32 House members said the halt to the Greenhouse Gas Reduction Fund grants undermines Congress’ spending power.

At what cost? - A new study, published in the Journal of the Association of Environmental and Resource Economists, found that relying on subsidies instead of effective carbon pricing is a costly strategy for the energy transition. The research, conducted by experts at the Paris School of Economics, examined how political constraints on carbon pricing shape climate policy. When high carbon taxes are infeasible, policymakers turn to subsidies for clean electricity and storage, which may improve acceptability but impose economic and fiscal costs, according to the paper. Using a stylised dynamic model with fossil and renewable energy sources and a carbon budget, the researchers showed that weaker carbon pricing requires increasingly large subsidies and may lead to excessive accumulation of clean capital to displace fossil fuels. A calibration to the European energy market indicates welfare losses of up to 2.6% and fiscal shortfalls equivalent to 56% of the present value of electricity consumption, the paper found.

A carbon credit rating agency is branching out into commodities, using its methodology to identify for investors and developers the best option when monetising lower emissions from a facility.

An American forest carbon project developer announced Tuesday that it had secured verification for its improved forest management (IFM) project with a major certification body.

BP has stopped its share buyback policy after profits in 2025 were hit by lower oil and gas prices, and shortly after investors questioned whether its fossil fuel reset would provide value for money.

A nonprofit announced its efforts to recruit national and sub-national governments to sign a non-binding cooperation agreement focused on implementing carbon removal (CDR) pathways responsibly.

Carbon critics - A New Mexico Senate bill (SB 18) that proposes economy-wide GHG emissions limits, among other proposals, has received criticism from a Republican lawmaker and representative of the fossil fuel industry for alleged potential economic detriments that they said would outweigh climate benefits, reported New Mexico Daily Lobo. Senator Anthony Thornton (R) said he fears the proposal would essentially establish a regulated carbon trading system.
