Developing Countries Create Most Global CO2 Emissions

From The Wall Street Journal, Real Time Economics, Commentary, "The Green New Deal’s Global Blind Spot: U.S. policy could do the most good by targeting innovation other countries can exploit" by Greg Ip:

The [Green New] deal targets U.S. emissions, yet the harm from global warming—extreme weather, heat, rising sea levels—comes from global emissions. This year, the U.S. will contribute 15% of the world’s carbon-dioxide emissions, according to the International Energy Agency. China will contribute 30% and India, 7%. By 2040, the U.S. share will drop to 12%, China’s to 27%, and India’s will rise to 14%.

Thus, even if the Green New Deal introduced by some Democrats last week succeeds in reducing U.S. emissions to zero, this will benefit Americans little unless other countries, in particular China and India, do the same.
