BEIS launches the new MacKay Carbon Calculator

The MacKay Carbon Calculator provides a model of the UK energy system that allows you to explore pathways to decarbonisation, including net zero by 2050.

Using the MacKay Carbon Calculator, you can create pathways to find out how we might reduce the UK’s greenhouse gas emissions to net zero by 2050 and beyond. You choose your ‘levels of ambition’ for decarbonising different parts of the energy system, and the calculator then shows how your choices affect UK emissions expressed as ‘carbon dioxide equivalent’ (CO2e).

Its purpose is to help everyone engage in the debate. It also allows government to explore how its plans support the path to net zero.

The calculator is named in honour of the late Sir David MacKay who was the driving force behind the first UK 2050 calculator. The original Calculator was released by DECC (now BEIS). 

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