[On the Global Climate Action Summit] I think that this summit’s been very useful. It’s a demonstration of activism, it’s a demonstration of will, it’s a demonstration of engagement by all sorts of sub-national players, and I think that’s all been tremendously useful. But, it doesn’t fill the gap of the absence of the United States at a national level. The US federal government can drive action all around the entire country, not just state-by-state.
