• Consultancy work exploring the land use changes in the Brazilian Savannah – in particular the resulting balance of GHG emissions. The research will also explore agriculture practices that can reduce emissions.
  • Work with Cornell University to quantify the biochar potential for New York State – a project led by Johannes Lehmann and John Gaunt.


UK Biochar Potential

Equal to 9% of UK emissions

  1. The UK can sequester up to 14 MtC/yr in biochar.
  2. From municipal and industrial waste streams, existing forestry residues and dedicated forestry for biochar.
  3. Biochar alone can compensate some but not all C emissions. Combined with zero emissions it could contribute to a net negative carbon target.

This research establishes the first estimate for biochar carbon sequestration in the UK. Biochar feedstocks were broadly assessed within two streams; forestry products and waste.

Forestry products include brash, tops, leaves and small roundwood. A separate scenario assessed the biochar potential of dedicating extra land for biomass production. This would use up to 30% of land currently under intensive agriculture.

Secondly waste streams were assessed, including animal waste, paper, cardboard and wood waste from municipal and industrial sources.

The total biomass attainable from these streams is 56 Mt/yr, with the main contributions from dedicated forestry and non-wood waste.

This study assumes biochar production with a basic pyrolysis conversion from biomass carbon to biochar carbon of 63%. This would sequester 14 MtC/yr, which is equal to 9% of UK CO2 emissions (7.7% of all GHGs).
