EPA kick-starts power plant carbon pollution standards with must-watch video for climate wonks and activists.

To help everyone build a common understanding of the range of opportunities for emission reductions, we want to take a moment to define some of these concepts. First, the ideas of a "source-based approach" and a "system-based approach." A source-based approach evaluates emission reduction measures that could be taken directly at the affected sources – in this case – the power plants. A system-based approach evaluates a broader portfolio of measures including those that could be taken beyond the affected sources but still reduce emissions at the source. And when we talk about source-based and system-based approaches, there are a few additional terms that we should recognize. First, supply-side options. This term generally refers to actions that occur at the regulated source itself or at other power plants. Second, demand-side options. This term generally refers to actions t...
