Campaign group Net Zero Watch is again calling for an inquiry into the Climate Change Committee (CCC), the Government’s official advisers on decarbonisation. The move follows revelations at the weekend that the CCC’s chief executive, Chris Stark, had tried to use obfuscation to “kill” questions over the adequacy of its energy system model, rather than addressing them directly. This behaviour put Stark in direct breach of the Nolan standards for public officeholders.

The scandal, published in the Sunday Telegraph, is just the latest of a series of controversies that have dogged the CCC since its inception.
