The Global Warming Policy Foundation, a climate skeptic think tank, has been reported to the Charity Commission by Green Party Member of Parliament Caroline Lucas and Extinction Rebellion. The move comes after the Guardian revealed that the group received funding from fossil fuel interests. The think tank has charitable status, but climate campaigners say the questions about its funding mean it should be stripped of this.
