How can reducing carbon in another location reduce the impact of climate change where I live?
Unlike some forms of pollution which have mostly local effects (like water pollution or noise pollution), the greenhouse gases that cause global warming are mixed in an atmospheric system that spans the entire planet. Carbon dioxide emitted in Brazil or Thailand is just as bad for your hometown as CO2 emitted from your own tailpipe. In the same way, global warming pollution prevented anywhere on the planet benefits the climate system equally.
