• Debate: Market vs. regulatory approaches to cutting carbon emissions

Supporting evidence

University of California Berkley Political Science Slide Show - "Political problems - The Clean Air Act requires all utilities generating electricity to use the "best available technology" to remove pollutants from emissions in coal-fired plants. All firms are required to install "smokestack scrubbers". But electric generators burn different types of coal.

• Anthracite: a "hard" coal with more carbon, which produces less

pollution

• Bituminous coal: a "soft" coal; produces less heat & more pollution
• Lignite: softer still; produces even less heat, but even more pollution

"'Best available technology' takes away economic advantage of burning harder, less polluting coal"
