This week is a big week for environment policy. On Monday, the President's Climate Action Plan celebrated its second birthday. That plan outlines a broad set of regulatory and diplomatic action to cut carbon emissions broadly from small passenger cars to large power plants. On Friday, the Administration could check off another box in their strategy as the U.S. Department of Transportation and the EPA issued the 1,600 page "Phase 2" proposed rule to advance fuel economy and reduce greenhouse gas emissions for medium and heavy-duty vehicles that was released last Friday afternoon. Those proposed rules kick-in beginning in model year 2021 and are anticipated to reduce carbon emissions by about 1 billion metric tons by 2027.
