A clean cooking project frontrunner, with aspirations to supply the CORSIA aviation offsetting scheme, has folded after the Kenyan government reportedly rejected the company's request for a Letter of Authorisation (LoA).

Captured value – South Korean researchers have developed a new electrode that captures CO2 from exhaust gases and converts it directly into formic acid in gas mixtures similar to industrial flue emissions, Interesting Engineering reports. The design combines a CO2-absorbing layer, a porous carbon sheet, and a tin(IV) oxide catalyst, enabling carbon capture and conversion to occur simultaneously in gases containing nitrogen and oxygen. The researchers said the approach could reduce costs by avoiding energy-intensive CO2 separation and could be adapted for methane.

A major voluntary carbon standard has applied its first labels of eligibility to credits for use under the international aviation sector’s offsetting scheme, it announced Friday.

Carbon questions – A US federal judge on Thursday issued supplemental questions ahead of a hearing, in the lawsuit against R.J. Reynolds Vapor Company, R.J. Reynolds Tobacco Company, and British American Tobacco (BAT). The judge asked plaintiffs and defendants to clarify how “carbon neutral” claims should be interpreted and substantiated in motions to dismiss a California consumer lawsuit. The court also asked plaintiffs and Reynolds to identify the controlling legal or regulatory definition of carbon neutrality in consumer marketing and whether a reasonable consumer would understand the term to require zero emissions or to allow third-party verified offsets. The hearing is scheduled for February.

Debt down - US-based methane abatement firm Zefiro eliminated almost $1.8 mln in debt and secured $447,500 in cash after three creditors exercised nearly 10.8 mln warrants, with most of the value offset against outstanding loans and the rest paid in cash. The remaining debt and accrued interest were settled via share issuance, reducing 2026 maturities by 64%. CEO Catherine Flax participated by converting $800,000 of her own loan and related interest into equity.

The number of carbon credit buyers choosing to remain anonymous fell year-on-year over 2025, according to analyst data published Friday.

The Bahamas’ lower legislative chamber is debating two bills following up on prior carbon market laws from 2022, triggering a debate centred on government rhetoric versus outcomes.

The Greenhouse Gas Protocol (GHG Protocol) has released its first dedicated global standard for accounting land-based emissions and carbon removals within corporate greenhouse gas (GHG) inventories, following five years of development, it announced Friday.

India’s push to scale up biofuels could feed directly into its emerging carbon market, even as gaps in accounting remain, the International Energy Agency (IEA) said in a report this week.

A major gas supplier in Japan has decided to expand the coverage of its carbon offset evaluation tool to include credits issued under the J-Credit scheme and Joint Crediting Mechanism (JCM).
