How energy efficiency cuts costs for a 2° C future

A new report — “How Energy Efficiency Cuts Costs for a 2° C Future” — analyzes how energy efficiency policies and programs in Brazil, China, Europe, India, Mexico, and the U.S. can reduce the cost of economy-wide decarbonization by up to $250 billion per year for these regions, with no net cost to society through 2030. “How Energy Efficiency Cuts Costs for a 2° C Future” modeled several pathways to identify the contribution of energy efficiency to achieving the internationally-agreed 2° C upper limit for climate change. The results show that, by following an energy efficiency pathway, policymakers can achieve low cost energy reductions through to 2030 while also cutting carbon emissions from the energy supply. In contrast, an energy intensive pathway that focuses primarily on decarbonizing energy supply with more limited energy efficiency policies can help achieve a 2° C future, but at substantially greater expense.
