Reducing greenhouse gas emissions: Lessons from state climate action plans

► This study analyzed climate action plans from 12 states and surveyed the advisory group members. ► Ten strategies supply 90% of recommended emission reductions, but states weigh them differently. ► Advisory group members perceived different opportunities and risks in the top-ten strategies. ► Both geographic and socio-political factors may underlie the varying reliance on certain strategies. ► Cost, business practices and consumer behavior were ranked as the top barriers to reducing emissions.
