Clean Air Act

The Trump administration took another step toward replacing the Clean Power Plan with its proposed Affordable Clean Energy (ACE) rule, published on August 21, 2018. The Clean Power Plan was developed by the Obama administration in 2015, but was stayed by the Supreme Court the following year and never implemented.  

Today the EPA released AVERT (Avoided Emissions and Generation Tool), an open-access tool built by Synapse to allow states and other stakeholders to estimate the hourly emissions benefits of energy efficiency and renewable energy policies and programs. AVERT allows non-expert users to measure emissions of CO2, SO2, and NOX mitigated by state or multi-state programs.
