当我们对全球气候变化负有责任时，我们都应该为一定的“市场价格”埋单。 这样我们才能真正地从经济上激励可持续的能源体系和新的公共投资—例如大运量公交系统—从而减少温室气体的排放，进而防止未来的气候灾难。
We will all need to pay a “market price” when we contribute to global climate change, so that we give true economic incentives to sustainable energy systems and new public investments – for example, mass transit – that reduce greenhouse gas emissions and thereby head off future climatic disasters.
