Two recent deals, one in the US and another in the UK, demonstrate that soil carbon can operate at scale and that new diverse buyers are entering the market. 

In the US, soil carbon project developer Boomitra has finalised a deal with Restoration Climate and the Ethereum Climate Platform for 500,000 soil carbon credits over five years, making it the largest of its kind to date.  

Meanwhile in the UK, a new carbon partnership between natural capital asset manager Oxygen Conservation and law firm Burges Salmon is marking a shift in the voluntary carbon market toward long-term, transparent investments in ecosystem recovery, biodiversity and social impact. 

The US agreement is tied to Boomitra’s Northern Mexico Grassland Restoration project which uses AI-powered remote sensing to measure carbon removal at scale, enabling revenue to flow directly to ranchers across 4m acres in Northern Mexico.

With projections to remove 25m tonnes of CO₂ in 20 years, the initiative showcases how regenerative agriculture and technology can unite to combat climate change while empowering communities. 

In the UK agreement, Burges Salmon will acquire up to 8,000 high-integrity carbon credits at £125 (€146.6) per tonne, funding a major nature restoration project on the Leighon Estate in Dartmoor, Devon.  

The credits, validated under the UK Woodland Carbon Code and verified by the Soil Association, will be generated through large-scale native woodland creation and restoration of ancient Atlantic rainforest. 

Managed by Oxygen Conservation and owned by The Dixon Foundation, the 861-acre Leighon Estate is one of the UK’s most ambitious nature restoration sites. Using a combination of natural regeneration, targeted tree planting, and drone-based monitoring, the project delivers far-reaching benefits—from improved biodiversity and water quality to rural jobs and environmental education.
