Negative Emissions Technologies

Carbon & Climate
Negative emissions technologies (NETs) remove CO₂ from the atmosphere, achieving net negative emissions. Methods include Direct Air Carbon Capture and Storage (DACCS), Bioenergy with CCS (BECCS), enhanced weathering, ocean alkalinity enhancement, biochar, afforestation/reforestation, and soil carbon sequestration. NETs are considered essential for net zero — the IPCC estimates 5-16 Gt CO₂/year removal needed by 2050. Current deployment is far below required scale.
