What are the 3 basic policy approaches to climate change?
The major greenhouse gas reduction policy approaches under consideration fall into three main categories: carbon pricing, technology subsidies, and performance standards.
Why is policy important in climate change?
Given the far-reaching nature of the climate challenge, effective federal policy is needed to achieve deep, long-term reductions in U.S. greenhouse gas emissions, and to help strengthen climate resilience across the U.S. economy.

What policies could be implemented to reduce warming in the Arctic?
Fast mitigation at scale can still slow future Arctic warming, starting with immediate cuts to the short-lived climate pollutants—black carbon, methane, tropospheric ozone, and hydrofluorocarbons. Cutting emissions of these short-lived pollutants immediately can reduce the rate of Arctic warming by up to two-thirds.
What actions and policies can be taken to adapt or mitigate for climate change?
