President Barack Obama's plan to raise Environmental Protection Agency emissions standards is a good start, but it addresses only power plants and will not cut emissions to the level we need to avert a worst-case scenario within a few decades ["The power of competition," Editorial, June 8].

The only measure that would result in a rapid decline in heat-trapping emissions is a gradually increasing carbon tax. The revenue-neutral carbon tax proposed by the nonpartisan group Citizens' Climate Lobby is economically sound and should satisfy those who prefer free-market solutions over government regulations.

Leading economists at both ends of the political spectrum agree that a carbon tax at energy sources would not only cut fossil fuel use, but would create an abundance of jobs in clean energy. Returning the revenue to households in the form of dividend checks would offset inflationary effects and render the plan palatable to conservative members of Congress.

A carbon tax would essentially level the economic playing field between fossil fuels and clean energy, and allow the free market to choose.
