2050 Pathways Calculator – UK

The 2050 Calculator is an award-winning, user-friendly model that lets users create their own UK emissions reduction pathway, and see the impact using real scientific data. The 2050 Calculator helps everyone engage in the debate and lets Government make sure our planning is consistent with this long-term aim. The UK is committed to reducing its greenhouse gas emissions by at least 80% by 2050, relative to 1990 levels. For this to happen, theĀ  UK economy needs to be transformed while ensuring secure, low-carbon energy supplies to 2050.

Key questions addressed:

  • How can my country feasibly reduce GHG emissions by at least 80% by 2050, relative to 1990 levels?
  • What are the GHG impacts and contributions of various behavioral and policy actions?

Sample data inputs:

  • Scenario option for each category

Sample quantitative outputs:

  • Supply and demand of energy and electricity
  • Total emissions
  • Energy flows
  • Area of land required
  • Impact on air quality
  • Energy security and cost

Accessing the tool:

The 2050 Calculator is available in three versions to allow a range of audiences to explore the fundamental question of how the UK can best meet energy needs while reducing emissions:

DECC is now working with teams around the world to help them develop their own calculators, and is also building a Global Calculator to look at ways to reduce emissions worldwide.
