Explore the science behind carbon removal

  • Biochar

    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.

    Permanence: MEDIUM From: £130/t
  • Enhanced weathering

    Enhanced rock weathering (ERW) takes natural weathering of silicate rocks that removes & mineralizes atmospheric CO₂ and speeds it up dramatically.

    Permanence: HIGH From: £246/t
  • Woody biomass sinking

    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.

    Permanence: MEDIUM From: £296/t
  • Direct air capture

    Direct air capture (DAC) is a chemical process to capture ambient CO₂ from the atmosphere.

    Permanence: HIGH From: £488/t
  • Bio-oil

    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.

    Permanence: HIGH From: £592/t
  • DAC with ocean storage

    This employs seawater electrolysis to capture and convert atmospheric CO₂ into carbonate solids for construction and permanently stores dissolved bicarbonate ions in the ocean.

    Permanence: HIGH From: £641/t
  • Tree planting

    Afforestation and forest restoration, if done effectively, combat climate change by removing carbon dioxide and protecting biodiversity.

    Permanence: LOW From: £41/t
