International trade has a critical role to play in environmental protection and the effort to mitigate climate change. While it certainly isn't always framed this way, it is important to realize that increased trade and economic growth are not necessarily incompatible with a cleaner environment and a healthier climate. If we are going to move away from dirty fossil fuels and inefficient energy processes at a rate necessary to limit the likely devastating results of a warmer planet, then we need enabling policies in place—especially when it comes to trade policy.
