Last week Pennsylvania Gov. Tom Wolf issued an executive order directing the Department of Environmental Protection (DEP) to join the Regional Greenhouse Gas Initiative (RGGI), joining nine other Northeast and Mid-Atlantic states in a market-based collaboration to reduce greenhouse gas emissions from power plants and combat climate change. And in North Carolina, Gov. Roy Cooper’s Climate Change Interagency Council presented four key plans related to clean energy and climate change, the result of the governor’s executive order signed last year to reaffirm the state’s commitment to fighting climate change and transition the state to a clean energy economy.
