  • Charcoal from Swedish trees could help to pull more CO2 from the atmosphere, and help slow climate change.
  • Biochar is a kind of charcoal that's produced by burning wood, without oxygen, and contains a lot of the carbon trees captured when they were growing.
  • Cecilia Hermansson at a Sjuhärad-based association is working on a way of standardising the climate effect, so that biochar producers could be paid.
