EPA’s Endangerment Finding on CO2 was never peer reviewed according to EPA’s Inspector General in 2011 and EPA did no science. The Obama administration issued the Finding anyway and proceeded to push CO2 regulations and hundreds of millions of dollars of CO2 projects.. This is an ethics violation at least and fraud at worst, especially in view of EPA’s funding of friendly environmental NGOs and their causes. EPA relied on UN IPCC reports, which is illegal, and the UN IPCC did no science. “Obama’s EPA used semantic tricks to avoid rigorous scientific evaluation. Is Trump’s EPA more honest?”
