Britain’s climate watchdog has privately admitted that a number of its key net zero recommendations may have relied on insufficient data, it has been claimed.

Sir Chris Llewellyn Smith, who led a recent Royal Society study on future energy supply, said that the Climate Change Committee only “looked at a single year” of data showing the number of windy days in a year when it made pronouncements on the extent to which the UK could rely on wind and solar farms to meet net zero.

“They have conceded privately that that was a mistake,” Sir Chris said in a presentation seen by this newspaper. In contrast, the Royal Society review examined 37 years worth of weather data.

Last week Sir Chris, an emeritus professor and former director of energy research at Oxford University, said that the remarks to which he was referring were made by Chris Stark, the Climate Change Committee’s chief executive. He said: “Might be best to say that Chris Stark conceded that my comment that the CCC relied on modelling that only uses a single year of weather data … is ‘an entirely valid criticism’.”
