Biochar and climate change
Standard Note: SN/SC/5144

Summary
• This note briefly introduces biochar as a measure to tackle climate change.
• Biochar is created by burning organic material to produce a charcoal-like substance.
• When buried in soil the carbon contained within biochar may be isolated from the
atmosphere for long periods.
• Some commentators believe that biochar will have an extremely important role in
reducing atmospheric concentrations of greenhouse gases—helping to avoid dangerous
climate change and improving agricultural productivity.
• Other commentators believe that the benefits are overstated and that there could be
negative environmental impacts.
• Some countries are seeking biochar mitigation to be included in the international climate
change framework being negotiated in 2009.
