UK regulations: the Climate Change Act
The Climate Change Act (2008) is part of the government’s plan to reduce greenhouse gas emissions. It established the framework to develop a targeted and economically-credible plan to reduce current and future emissions.
The act highlights the UK’s commitment to urgent international action to tackle climate change.
How the Climate Change Act affects UK policy
Through the Climate Change Act, the government has set targets and created several groups and programmes to work on limiting and adapting to climate change.
The Committee on Climate Change (CCC)
The CCC was set up to:
- advise the government on emissions targets
- report to Parliament on progress made in reducing greenhouse gas emissions
The committee includes the Adaptation Sub-Committee (ASC), which scrutinises and advises on the government’s programme for adapting to climate change.
The Climate Change Act commits the government to reducing greenhouse gas emissions by at least 80% of 1990 levels by 2050. This includes reducing emissions from the devolved administrations (Scotland, Wales and Northern Ireland), which currently account for about 20% of the UK’s emissions.
This target was based on advice from the CCC’s 2008 report, ‘Building a low-carbon economy’.
The Climate Change Act requires the government to set legally-binding ‘carbon budgets’. A carbon budget is a cap on the amount of greenhouse gases emitted in the UK over a five-year period.
The CCC advises on the appropriate level of each carbon budget. The budgets are designed to reflect a cost-effective way of achieving the UK’s long-term climate objectives.
The first five carbon budgets have been put into legislation and will run up to 2032.
The national adaptation programme
Through the Climate Change Act, the government created the national adaptation programme to:
- assess the risks to the UK from climate change
- prepare a strategy to address them
- encourage key organisations to do the same

The Infrastructure Act 2015
Under the Infrastructure Act 2015, the CCC has a duty to advise the government on the implications of exploiting onshore petroleum, including shale gas, for meeting UK carbon budgets. The CCC provided advice on onshore petroleum in 2016.
Who is responsible for climate change policies
Preventing dangerous climate change, and preparing for it, touches on all aspects of the economy. Therefore several government departments provide input into climate change policies.
The two main government departments responsible are:
- Department for Business, Energy and Industrial Strategy (BEIS) – leading on the policy for reducing emissions (mitigation)
- Department for Environment and Rural Affairs (Defra) – leading on the adaptation policy
BEIS is responsible for ensuring secure energy and promoting action on climate change in the UK and internationally.
Defra is responsible for developing a national adaptation programme to address the risks set out in the most recent UK climate change risk assessment (2017).
The governments and assemblies of the devolved administrations (Scotland, Wales and Northern Ireland):
- create climate change policy for their devolved area
- help to implement UK-wide policies
As well as being covered by the Climate Change Act, Scotland, Wales and Northern Ireland have their own climate change policies. For example:
- the Climate Change (Scotland) Act 2009 commits Scotland to a 42% reduction in emissions by 2020 and annual reductions between 2010 and 2050
- the Northern Ireland Assembly is developing plans for a Northern Ireland Climate Change Act, following advice from the CCC
- the Welsovernment is considering how to set its own carbon budgets
