Carbon-Removal
Where it's used
Agroecology & regenerative farming
A bundle of practices — no-till, cover crops, microbial nitrogen, agroforestry and rotational grazing — that rebuild soil carbon and cut synthetic inputs while keeping yield, increasingly bought by food majors under Scope-3 and carbon-credit programmes.
BECCS
Bioenergy with carbon capture and storage — burning biomass for power or heat and permanently storing the resulting biogenic CO2 — is moving from single flagship pilots to a small cluster of near-term commercial projects in Northern Europe, while a marquee US project shows how permitting risk, not the underlying chemistry, is what actually delays BECCS at scale.
Enhanced rock weathering
Crushed silicate rock — usually basalt — spread on farmland to accelerate the natural weathering reaction that draws down atmospheric CO2 into stable dissolved bicarbonate, with the added draw of a real agronomic side-benefit: the same application also raises soil pH and releases nutrients.
