The 2050 Calculator Programme

The UK Department for Energy Security and Net Zero (DESNZ), Mott MacDonald, Imperial College London, Ricardo and Climact are working in partnership to deliver the activities of the DESNZ-funded International 2050 Calculator programme. The 2050 Calculator is a uniquely open and transparent energy model that can be used by governments, stakeholders and the public to understand how to decarbonise a region or country, and to develop evidence-based policies. It was originally developed for use in the UK but is now being used in over 30 countries. 

The 2050 Calculator Programme runs from January 2019 to December 2023. It includes the following three workstreams:  

  1. Support to five new countries to develop their own versions of the 2050 Calculators
  2. Support of further work on completed Calculators to make them more useful for policymakers and to promote them to stakeholders  
  3. Grow the 2050 Calculator community and promote South-South learning, including annual international workshop

This site provides a central community for Calculator stakeholders to share best practice, improve tools and help each other to build bespoke Calculator country models.
