Direct air capture + storage
Look for: the energy source and its carbon intensity, energy demand per tonne, storage partner and injection permits, and metered capture data rather than nameplate capacity.
- High durability
- Strong MRV
- Energy-intensive
Project directory
Who is building carbon removal — and how to evaluate them.
The directory is a reference layer for partners, funders, and researchers: what each removal pathway looks like on the ground, what evidence a credible project shows, and how to get a project listed as the directory opens up.
Pathway reference
What "good" looks like, per pathway
Use these as a diligence starting point when a project crosses your desk.
Biochar
Look for: feedstock sourcing and competition, pyrolysis conditions (they drive carbon stability), application tracking, and which registry methodology the project follows.
- Deployable now
- Co-benefits
- Decades–centuries durability
Mineralization & weathering
Look for: feedstock chemistry and logistics, measurement approach for open-system weathering, and independent sampling — this is the pathway where MRV method matters most.
- Very durable
- MRV frontier
- Feedstock-bound
BECCS & bio-oil
Look for: biomass sustainability criteria, counterfactual use of the feedstock, capture rates, and storage confirmation — the value chain has more links to verify.
- Energy + removal
- Land constraints
- Chain-of-custody
Listing criteria
What we ask of listed projects
- Public, verifiable information — a real site, team, and pathway description.
- Methodology transparency: which protocol or registry the project measures against.
- An MRV story: what is measured, by whom, and how often.
- Community context: where the project operates and who it affects.
Listings are references, not endorsements — buyers and investors should always run their own diligence.

New plants, new offtakes, and new pathways surface in the daily signal first. The directory grows as the sector does.

Model a plant yourself
Before you take a capacity claim at face value, run the numbers: the solar CO2-removal lab turns capacity, energy demand, and cost into tonnes, land, and scale.
