This report responds to a request from the Governments of the UK, Wales and Scotland, asking the Committee to reassess the UK’s long-term emissions targets. Our new emissions scenarios draw on ten new research projects, three expert advisory groups, and reviews of the work of the IPCC and others.
The reports key findings are that:
The Committee on Climate Change recommends a new emissions target for the UK: net-zero greenhouse gases by 2050.
In Scotland, the Committee recommends a net-zero date of 2045, reflecting Scotland’s greater relative capacity to remove emissions than the UK as a whole.
In Wales, the Committee recommends a 95% reduction in greenhouse gases by 2050.
A net-zero GHG target for 2050 will deliver on the commitment that the UK made by signing the Paris Agreement. It is achievable with known technologies, alongside improvements in people’s lives, and within the expected economic cost that Parliament accepted when it legislated the existing 2050 target for an 80% reduction from 1990.
However, this is only possible if clear, stable and well-designed policies to reduce emissions further are introduced across the economy without delay. Current policy is insufficient for even the existing targets.
The Committee also published a technical report which provides detailed analysis that has been carried out for each sector of the economy, plus consideration of F-gas emissions and greenhouse gas removals.

A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
The contribution of buildings to climate change has become widely acknowledged. On 3 December 2015, the United Nations Environment Programme (UNEP) held the first ‘buildings day’ at COP 21 (the UN Climate Change Conference) devoted to the decarbonization of the building stock.
This report aims to help policymakers identify what options could be included in a low-cost policy package (a combination of policies, measures, and technologies) to achieve Mexico´s Greenhouse Gas abatement targets and a more ambitious emissions trajectory, along with the benefits associated with both.
