2. Declines in CO2 emissions in 2017 were led by the US (-0.5% and 42 million tons). 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.
3. Carbon emissions from energy use from the US are the lowest since 1992, the year that the United Nations Framework Convention on Climate Change (UNFCCC) came into existence. The next largest decline was in Ukraine (-10.1% and 28.1 tons).
