Interesting visualization by the World Resource Institute, mapping greenhouse gas emissions of various countries onto US states. See The State of U.S. Emissions, Part I and How U.S. State GHG Emissions Compare Internationally.
The maps show, for instance:
- Every US state is equivalent to an entire country in terms of GHG emissions.
- Six US states (Texas, California, Pennsylvania, Ohio, Illinois and Florida) rank among the top 30 emitters internationally.
- Texas emissions alone are equivalent to Canada (760 million tonnes).
- Michigan is equivalent to the Netherlands (219 million tonnes).
Apart from visualizing emissions data, the maps are also insightful for (future) US climate change policy:
For starters, each state has its own unique circumstances with respect to its GHG emissions and its capacity to reduce them. In that sense, federal and U.S. state policies are analogous to global efforts under the UN Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol, which refer to countries' common but differentiated responsibilities.
Second, regardless of federal action, states can make a significant global difference. Each state can reduce its emissions on a scale equivalent to at least one member of the Kyoto Protocol. Acting together, states could reduce emissions on a scale equal to a major developed or developing country. That said, there is no doubt that a comprehensive U.S. policy will be needed to reduce emissions on the scale required.
