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.
Financing the upfront costs of energy efficiency and renewable energy projects in buildings can be a significant barrier to the expansion of sustainable, low carbon buildings, despite this being a low-cost option on the carbon abatement curve. Systematic literature on...Read more

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.
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. There are several forms of negative contributions that buildings make to climate change, but high on the list are embodied and operational energy demands, which largely depend on fossil fuels and result in greenhouse gas emissions.
Various policies targeting at building energy efficiency have been promulgated by the Chinese government in the past decade. However, few studies evaluate if China is on the right path to meet its energy goals through these policies by providing an assessment of their effect in reducing energy consumption in residential buildings or the feasibility of such policies to catalyze these reductions.
