As an example, you could direct the Environmental Protection Agency (EPA) to impose fees on sales of gasoline. The revenues of such fees could then be earmarked to fund ways to make the use of genuinely clean energy more attractive.
The duty to act on climate change can delegated to states, provided that sufficient progress is made to combat climate change. States can thus to a large extent decide what action and what mix of policies they feel will work best where. Where such progress is lacking, federal authority can resume control, impose fees in the respective state and decide to direct (part of) revenues to federal programs, such as construction of high speed rail tracks that cross state borders, waste management in national parks, federal research grants into ways to combat climate change, etc.
State administrators can similarly decide to delegate their authority to local levels, allowing each local council to implement feebates believed to work best in the respective area. And similarly, state administrators can resume control in case of a lack of progress in a specific area, and direct the revenues to state programs.
Further action will be needed to reduce the danger of catastrophic climate change, which calls for a comprehensive climate plan such as described at http://climateplan.blogspot.com
