The Foundation for Economic Education (7/17/18) op-ed: “Declines in CO2 emissions in 2017 were led by the US (-0.5% and 42 million tons, see chart above). This is the ninth time in this century that the US has had the largest decline in emissions in the world. This also was the third consecutive year that emissions in the US declined, though the fall was the smallest over the last three years.”
