The ELUM Software Package spatially predicts the net soil greenhouse gas balance of land-use change to grow energy crops in the UK up to 2050. It is able to support a range of analyses of bioenergy, and was developed in consultation with anticipated users. Results can be obtained according to specific interests, viewed in the graphical interface and exported for a variety of purposes. The functionality of the software is demonstrated through different case studies, which show an array of applications. •ELUM models soil greenhouse gas balance of bioenergy land-use change in UK to 2050.•It is based on the ECOSSE model, but quick and easy to use, with added features.•It is able to support life-cycle assessments and policy making for bioenergy.•Consultation with anticipated users guided usability and functionality.•Greenhouse gas balance is highly dependent on initial land use and new energy crop.
