Carbon credit retirements have accelerated across multiple distinct market segments, with a landmark US energy company transaction, a milestone for the carbon dioxide removal (CDR) sector, and compliance-driven activity in South Africa providing a convergent view of the verified carbon market in active use.

US energy company Hess Corporation retired 12.5 million carbon credits—valued at approximately $250 million based on a purchase agreement announced in 2022—in what has been described as one of the largest single transfers of value from the fossil fuel sector to nature-based carbon projects. The scale of the transaction underscores a broader recognition: carbon credits derive their value from deployment, not accumulation.
The CDR segment reached its own landmark when Finland-based standard Puro.earth confirmed that cumulative retirements of its CO2 Removal Certificates (CORCs) have passed one million. The milestone follows sharp growth: the average time between a CORC’s issuance and its primary trade fell from 115 days in 2024 to seven days in 2026. Retirements on the Puro registry grew 112% in 2025 and 140% in 2024.
‘One million retirements is not just a number—it is evidence that the market is working as it should. Buyers are not just purchasing credits and waiting to retire them’, said Puro.earth President Jan-Willem Bode. Biochar represents the largest share of retired CORCs at 48.1%, with geologically stored carbon accounting for a further 33.3%.

Compliance obligations continued to generate significant retirement volumes in South Africa, where registry data points to activity under the country’s Carbon Offset Administration System (COAS). Energy Joburg RF retired approximately 228,000 tonnes of CO2 equivalent (tCO2e) from a Johannesburg landfill gas project, and Eden Exchange retired 136,000 tCO2e from a domestic fuel efficiency and lighting project—both verified under Verra.
Two first-time buyers from China's manufacturing sector broadened the verified carbon market's industrial base. Nanjing Weigang Dairy, a dairy producer, retired 21,000 tCO2e from domestic renewables credits, joining a buyer cohort that includes sector peer Yili Dairy. Jiangsu Enjie New Material Technology, a lithium battery separator manufacturer, retired 10,000 tCO2e from agricultural methane recovery projects—reflecting wider adoption of verified credit procurement across China's battery supply chain. Simultaneously, French energy services firm Selectra added 47,000 tCO2e from Turkish renewables to its 2026 total, bringing its year-to-date figure to 393,000 tCO2e.

Taken together, the most recent retirement data reflects a market in which credits are being actively deployed rather than accumulated—across regulatory, removal, and corporate pathways, and across an increasingly diverse buyer base.
As demand for trusted, high-quality carbon credits grows, the standards behind each credit matter more than ever. Green Earth develops large-scale nature-based carbon projects accredited to leading international standards, with full supply chain oversight from initial design through to long-term monitoring and credit issuance. Every project delivers verified environmental impact across ecosystems, communities, and biodiversity—built to the highest levels of regulatory scrutiny.
