claimThe Environmental Protection Agency (EPA) has been working to regulate greenhouse gas emissions through administrative policy, acting as a substitute for the cap-and-trade legislation that Congress failed to pass.
claimThe EPA relied on the 2007 IPCC report and data from the NCDC to establish its 2009 endangerment finding regarding greenhouse gas emissions.
claimIn April 2009, the EPA issued an endangerment finding stating that current and future greenhouse gas emissions pose a serious threat to public health and safety.
claimThe Environmental Protection Agency is pursuing a regulatory path to decrease carbon dioxide emissions.
perspectiveThe Heritage Foundation recommends that the United States Congress should amend the Clean Air Act to exclude carbon dioxide and other greenhouse gases from the regulatory authority of the Environmental Protection Agency (EPA).
claimThe Supreme Court ordered the EPA administrator to determine if greenhouse gas emissions were dangerous to human health and the environment and whether the scientific consensus on the effects of greenhouse gases was settled.
perspectiveCongress should not implement any new greenhouse gas (GHG) reduction policies and should prohibit the Environmental Protection Agency (EPA) from doing the same, due to inconclusive scientific evidence.
