The wedges approach to reducing emissions

The "wedges" approach to climate change mitigation is one that needs more coverage in the press. The basic idea is that we need to do several things, not just one or two, to reduce CO2 emissions. Carbon caps are not enough by themselves. Energy efficiency is not enough by itself. You can read more at the HQ for this idea, the Princeton Environmental Institute.

Here's a small, very small, start at some media coverage. An original article by Shawn Dell-Joyce in the Middletown, NY, Times Herald-Record does a good job introducing the idea.

A good explanation also appears in this essay by truthout's Kelpie Wilson. Its important to consider the economic costs of each wedge when deciding what to do. Unfortunately, estimating those costs is an inexact science.
