A commercial carbon-capture coal-burning [ power plant has opened. ]( http://www.theguardian.com/environment/2014/oct/01/canada-switches-on-worlds-first-carbon-capture-power-plant ) In principle this can be part of a solution for reducing greenhouse gas emissions. If other forms of fossil fuel are cheaper, a simple tax can make them more expensive. Subsidizing fossil fuel use is harmful, but subsidizing a decrease in the CO2 emissions from fossil fuel use makes sense.
