Trump Scraps Key Climate Emission Regulation, Sparking Global Concern

• US President Donald Trump announced the EPA repealed its 2009 legal finding that greenhouse gas emissions endanger human health.
• This 'endangerment finding' provided the legal basis for federal regulation of greenhouse gases, including Obama's Clean Power Plan.
• Without this finding, the federal government lacks a direct legal mandate to regulate greenhouse emissions without new congressional laws.
• The move is seen as the biggest blow to US decarbonization efforts, potentially increasing global emissions.
• The decision is expected to trigger numerous court cases, but could leave a future Democratic president without an easy regulatory tool.
