EPA Hedges On Changes To Carbon Cost, Health Benefits In CPP Analysis

摘要

Despite making many significant departures from Obama EPA cost-benefit analysis used to justify the Clean Power Plan (CPP), the Trump EPA's analysis of its proposed CPP repeal hedges on some key issues, including possibly using Obama-era estimates for the social cost of carbon (SCC) due to "uncertainty." The agency's draft regulatory impact analysis (RIA) also suggests that it might alter its assumptions that there arc no health-related co-benefits of reducing fine paniculate matter (PM2.5) below the national ambient air quality standard (NAAQS) alongside the rule's targeted pollutant of greenhouse gases.
