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. Even in the absence of a comprehensive federal approach, the federal government can help accelerate progress being made by cities, states, and companies. Federal policymakers have a number of policy tools at their disposal:
- Government research and development programs, such as the Advanced Research Project Agency-Energy, can drive progress in clean energy technologies and bring them to commercial use.
- Voluntary programs, like the Natural Gas STAR program, work with businesses to reduce emissions, often with public recognition.
- Traditional regulations, such as fuel efficiency and emissions standards for cars and trucks, require companies to increase energy efficiency or reduce emissions in their own operations or in the goods they produce.
- Market-based programs that put a price on carbon emissions, such as a carbon tax or cap-and-trade program, require emission reductions but let the private sector determine the most cost-effective way to achieve them.
