To ask the Secretary of State for Business, Energy and Industrial Strategy, how much electricity and gas was generated by anaerobic digestion in (a) 2015 and (b) 2016; and how much CO2 or CO2e, CO2 equivalent, was emitted by anaerobic digestion in each of those years.

The table below shows how much electricity and heat (on a fuel input basis) was generated by anaerobic digestion (AD) in 2015 and 2016, as well as emissions from Anaerobic digestion in 2015. Emissions from anaerobic digestion include methane and nitrous oxide emissions from the anaerobic digestion process; carbon dioxide emissions from anaerobic digestion are not included in the UK’s greenhouse gas emissions inventory because this is biogenic source. Emissions data for 2016 will be available in February 2018.
