To be redundant, it's clear that both candidates are market liberals. Both believe in the the ability of the market and incentives for the transformation of our economy and our environmental footprint. The use of incentives is the most basic characteristic of the market liberal philosophy. By playing to the means by which corporations and companies operate, incentives can be a very effective means by which change can be accomplished. Any other approach to overhaul the system and the means by which it operates would be silly and ineffective.

The candidates both seem to be on the right page and I really don't think that choosing one or the other would lead to any further environmental harm than can be already expected. That being said, Democrats seem to traditionally be more on top of their game with regards to the environment giving Obama an edge. However, John McCain seems to have broken some traditional Republican typecasts by his environmental policies as well.
