About us

What we do

The Department of Energy & Climate Change (DECC) works to make sure the UK has secure, clean, affordable energy supplies and promote international action to mitigate climate change.


We are responsible for:

  • energy security – making sure UK businesses and households have secure supplies of energy for light and power, heat and transport
  • action on climate change – leading government efforts to mitigate climate change, both through international action and cutting UK greenhouse gas emissions by at least 80% by 2050 (including by sourcing at least 15% of our energy from renewables sources by 2020)
  • renewable energy – sourcing at least 15% of our energy from renewable sources by 2020
  • affordability – delivering secure, low-carbon energy at the least cost to consumers, taxpayers and the economy
  • fairness – making sure the costs and benefits of our policies are distributed fairly so that we protect the most vulnerable and fuel poor households and address competitiveness problems faced by energy intensive industries
  • supporting growth – delivering our policies in a way that maximises the benefits to the economy in terms of jobs, growth and investment, including by making the most of our existing oil and gas reserves and seizing the opportunities presented by the rise of the global green economy
  • managing the UK’s energy legacy safely, securely and cost effectively


The Department has four objectives:

  1. Security And Resilience: ensure the UK has a secure and resilient energy system
  2. Keeping bills low: keep energy bills as low as possible for households and businesses
  3. Decarbonisation: secure ambitious international action on climate change and reduce carbon emissions cost-effectively at home
  4. Energy legacy: manage the UK’s energy legacy safely and responsibly
