Trade association builds a carbon portfolio - The environmental conservation organisation VitalEco is teaming with an Arizona trade association to launch a portfolio of carbon projects.

The portfolio includes three categories: orphaned well plugging projects for methane emissions abatement, biochar and biogenic projects, and regenerative agriculture projects. VitalEco will also donate a portion of its proceeds from carbon credit sales back to the trade association.

Rising demand for high-integrity nature-based credits continues to support prices and increase the need for higher-quality data, with Earth observation (EO) and ground-based measurements being combined to verify carbon project outcomes, a webinar heard on Wednesday.

Forest carbon programmes are aiming to recruit small forest owners in Maine as economic pressures push many to timber their forests prematurely or sell land to developers, carbon developers said Wednesday.

More ratings - Emsurge Open Markets (EOM), a UK-based marketplace, has teamed up with Calyx Global to show GHG and SDG ratings directly to traders buying and selling carbon credits. As part of the partnership, Emstream broker prices for available supply, captured on EOM, will be made available to Calyx customers via rating agency's platform. The partnership will help Calyx to identify actively-traded projects to rate, allowing it to respond to the market and add to the 1,000+ GHG and 500+ SDG ratings the company has generated to date, said Donna Lee, co-founder of the rating agency, in a statement.

Indonesia covered - Space Intelligence, a UK-based forest data and analytics company, has mapped 189 mln ha of Indonesia across seven time periods between 2014 and 2025, producing land-cover datasets used by project developers and governments worldwide, it recently announced at the Global Carbon Summit Indonesia 2025, hosted by Ecobiz Asia. Murray Collins, chief executive of the company, warned that many actors still depend on legacy, slow, and uncertain analytical methods, including manual map reviews and inconsistent datasets, which create delays and heighten technical risks in project pipelines.  If you cannot accurately quantify carbon potential or detect degradation, you cannot build a credible project, he told the conference, according to Ecobiz. He cited common bottlenecks: weeks-long screening processes, uncertainties in land-use change data, and difficulties in detecting subtle forest degradation that could undermine carbon credit issuance.

Latin American carbon markets are welcoming new regulatory infrastructure, concrete state-led planning, and varied methodological offerings from standards based in the region.
