        <RULE_TITLE>Endangerment and Cause or Contribute Findings for Greenhouse Gases Under Section 202(a) of the Clean Air Act</RULE_TITLE>
        <ABSTRACT><![CDATA[On April 17, 2009, the Administrator proposed an Endangerment Finding under section 202(a) of the Clean Air Act.  This proposed finding had two components.  First, the Administrator proposed to find that the current and projected concentrations of the mix of six key greenhouse gases--carbon dioxide (CO2), methane (CH4), nitrous oxide  (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)--in the atmosphere endanger the public health and welfare of current and future generations through climate change.  In the second component of the proposal, known as the Cause or Contribute Finding, the Administrator further proposed to find that the combined emissions of four of these six greenhouse gases from new motor vehicles and motor vehicle engines contribute to the atmospheric concentrations of these key  greenhouse gases and hence to the threat of climate change.  EPA has not proposed in this action any new regulation of motor vehicle or motor vehicle emissions.]]></ABSTRACT>
