The UK Biomass and Biogas Carbon Calculator is developed for calculating carbon intensity and greenhouse gas (GHG) saving of solid biomass and biogas used for electricity and heat generation. The UK Biomass & Biogas Carbon Calculator incorporates the calculation methodology set out in the Renewable Energy Directive1a, taking account of the recommendations set out by the European Commission in their report on sustainability requirements for solid and gaseous biomass1b. The tool is designed to assist in calculating the final GHG emission saving that should be reported to Ofgem.

Ensuring that calculation of GHG savings is undertaken correctly remains the responsibility of generators, as set out in the Renewable Obligation Order.

The UK Biomass and Biogas Carbon Calculator was developed by E4tech, with support from the Environment Agency, the Department of Energy and Climate Change and the NNFCC.

DECC have commissioned a consortium led by NNFCC and including E4tech, to provide support to users of the Biomass and Biogas Carbon Calculator. If you have queries in relation the software that cannot be addressed by the User Guide, please email This support is limited to technical queries on the calculator only. Any queries associated with the RO greenhouse gas criteria and other aspects of the sustainability criteria and reporting should be directed to Ofgem.
