Today at the California Air Resources Board meeting, a historic plan is being presented that may radically cut greenhouse gas emissions in the state by about 30% by 2020. "The state is proposing a slate of changes including a cap-and-trade system for greenhouse gases, requiring renewable sources to power a third of the state's grid and taxing gas guzzling cars. Their approach will become a model for the nation if climate change legislation of some sort passes through Congress and is signed by the next President in 2009 as is widely expected." Wired is at the meeting updating what's happening. (emphasis added)
