Energy issues are environmental issues, and environmental issues increasingly are energy issues. This link is inescapable: energy decisions have profound environmental and public health impacts, and energy-related emissions are changing the heat balance of Earth. The purpose of this paper is to demonstrate that greater integration and coordination of energy and environmental regulation can improve both environmental and energy outcomes – as well as citizens’ quality of life and economic wellbeing – and to provide some advice and guidance for moving effectively in this direction.
