Significant reductions in greenhouse gas emissions are necessary to limit climate change and stay under two degrees of warming, and immediate action is needed to put the world on a path to a reasonable climate future. Evidence is mounting of potential damage from climate change, and each day that passes makes decarbonization to reach the two degree goal more difficult.

It’s a daunting challenge, but the technologies and strategies to meet it exist today. Ten policies in just five sectors of the economy, plus land-use emissions reductions, can reach this goal.

Government officials and other policymakers need a clear resource outlining which energy policies can put us on the path to a low-carbon future, and how to best design those policies.

Designing Climate Solutions: A Policy Guide for Low-Carbon Energy is the first such resource, combining the latest research and analysis on low-carbon energy solutions from electric vehicles to renewable energy. It is the first book to identify which specific policies, applied to the top 20 most-emitting countries, can have the largest potential impact to reduce emissions enough for a 50% chance of keeping global warming to a safe level.

And, it is the first outline of which shared policy design principles can make the difference between policies that work and policies that miss their goal.
