His five-year term of leading the Committee was due to end this year but it has been extended until September 2022.
Since 2012, the CCC has advised government on the fourth and fifth carbon budgets, emission reductions targets and reported to Parliament annually on the nation’s progress in reducing greenhouse gas emissions.
Committee Member Paul Johnson’s five-year term has also been extended.
Climate Change and Industry Minister Claire Perry said: “The UK was the first country to introduce legally binding emission reduction targets under the Climate Change Act and we have led the G7 group of countries in cutting our emissions, while growing our economy by more than two-thirds since 1990.
“The independent advice provided by Lord Deben, Paul Johnson and the entire Committee will help us continue to lead the world in clean growth.”
