The 2050 Calculator is a transparent tool designed to illustrate the different options available to the UK for meeting its goal of reducing emissions by 80% in 2050, on 1990 levels, whilst ensuring a secure supply of energy. It covers all major sectors of the economy including energy, transport, industry and households, allowing the user to vary the level of action by area and technology. It uses the best available information from engineers, economists and scientists on what is technically possible.

The 2050 Calculator also introduces the concept of “total energy system cost”.  This includes the cost of everything from power stations and industrial processes; to cars, planes and trains and the fuel they use; to gas boilers and cavity wall insulation.  Costs are expressed as £/person/year; this is the cost to the overall economy and is not the same as household electricity and heating bills.  The cost of not tackling climate change is not included in the Calculator, but the Stern Review estimated damages arising from population shifts, severe weather patterns and lost ecosystems could amount to a cost of up to 20% of global GDP.
