Negative Emissions

 

Negative emissions involve strategies which remove greenhouse gases from the atmosphere. 

Carbon Brief documented 10 of the most frequently proposed negative emissions technologies (NETs):

  1. Direct air capture
  2. Cloud or ocean treatment with alkali
  3. Enhanced weathering
  4. Enhanced ocean productivity
  5. ‘Blue carbon’ habitat restoration
  6. Afforestation and reforestation
  7. BECCS
  8. Building with biomass
  9. Biochar
  10. Soil carbon sequestration

However, some strategies reduce warming without reducing the amount of greenhouse gases in the atmosphere and that does nothing to reduce ocean acidification which many see as a greater threat to our wellbeing.
