We source, create, and guarantee the supply your net-zero target demands. The marketplace for buyers who need delivery, not hope.
Last year, projects that passed our vetting sold 4:1 the rate of lower-quality supply. The best tonnes aren't sitting on a shelf. They're locked into exclusive long-term deals before most buyers even start looking.
The gap is about to widen. 55% of biochar projects failed to launch last year. SBTi mandates permanent CDR procurement from 2028, and most companies underestimate how much they’ll need.
Buyers can secure supply now—or scramble for what’s left later.
Read our market data reportsWe find the best projects, co-develop new supply from scratch, and provide distribution. When the right project doesn’t exist, we create it. We hold a three-year agreement with Exomad Green, the world's #1 biochar project, for up to 500,000 tonnes through 2028.
Delivery risk is real. We build three layers of protection: buffer pool credits, pre-vetted pathway alternatives from 80% market coverage, and contracts designed for delivery variability. When a project underdelivers, your portfolio absorbs it.
Our climate science team, led by Dr. Mai Bui, advises SBTi on CDR guidance and sits on the Puro.earth scientific advisory board. We’re in the room when the standards are written, so you can stay ahead of shifting regulation. 118-point vetting framework. 84% of projects assessed don’t make the cut.
We worked with a pre-operational biochar project to facilitate a 1M tonne offtake with Microsoft. Our experts helped early stage design of the project, ensuring needed scale and MRV to meet Microsoft’s rigorous standards.
We track 600+ suppliers across eight removal methods: biochar, BECCS, enhanced rock weathering, direct air capture, marine CDR, bio-oil, biomass burial, and mineralization. We go deepest where the market is ready—biochar today, expanding as other methods mature.
Biochar is charcoal-like material rich in stable carbon. It is produced by heating biomass in an oxygen-limited environment in a process called pyrolysis.
Bioenergy with carbon capture and storage (BECCS) is a powerful engineered carbon removal method. Biomass absorbs atmospheric CO₂ as it grows. BECCS captures the CO₂ when the biomass is used to generate energy and stores it underground for thousands of years or longer.
Enhanced rock weathering (ERW) takes natural weathering of silicate rocks that removes & mineralizes atmospheric CO₂ and speeds it up dramatically.
Direct air capture (DAC) is a chemical process to capture ambient CO₂ from the atmosphere.
This employs seawater electrolysis to capture and convert atmospheric CO₂ into carbonate solids for construction and permanently stores dissolved bicarbonate ions in the ocean.
This is a method that sequesters carbon by submerging leftover woody materials in the oxygen-depleted layer of the Black Sea, which is approximately 2 kilometers deep.
Bio-oil and biochar production both convert waste biomass through pyrolysis. Bio-oil is a liquid stored in geological repositories, while biochar is applied to soils.
Every tonne we sell is permanent, verified carbon removal. Whether you're planning your first CDR purchase or scaling a decade-long portfolio, we source, create, and guarantee the supply you need.
