Net Zero Technical Report

Share this Post:

This technical report accompanies the 'Net Zero' advice report which is the Committee's recommendation to the UK Government and Devolved Administrations on the date for a net-zero emissions target in the UK and revised long-term targets in Scotland and Wales. England, Scotland, Wales and Northern Ireland each have an important role to play in delivering a UK net-zero emissions target. However, each devolved administration has a unique set of opportunities and challenges in achieving net-zero emissions, meaning that the combination of options will differ across the UK. We have therefore determined what each UK-wide scenario means for each devolved administration, as well as an assessment of whether and when each devolved administration could credibly achieve net-zero domestic emissions.

 

The analysis of decarbonisation options by sector is brought together in the form of our economy-wide scenarios. They have been formed using a "bottom-up" approach which allows a detailed assessment of the options relevant to each source of emissions.

 

Our scenarios illustrate ways in which extensive decarbonisation of the UK economy could occur by 2050. This allows us to demonstrate whether a net-zero emissions target by 2050 is plausible, in terms of both the actions required and the costs involved. In each sector chapter we also consider the earliest date at which each Further Ambition option could be delivered, to allow an assessment of the potential to decarbonise before 2050.

 

This technical report mainly addresses the resource costs of net-zero emissions scenarios across the economy. Resource costs are estimated by adding up costs and cost savings from carbon abatement measures and comparing them to costs in an alternative scenario: generally a hypothetical world with no climate action or climate damages.
