Back in 1997, President Bill Clinton signed on to the goals and processes of the Kyoto Protocol, which commits signatory countries to reduce greenhouse gases in amounts sufficient to prevent dangerous man-made interference with the climate.
The interim goal laid out in 2018 called for a 45% reduction in greenhouse gases from 2010 to 2030. To meet that target, the world would need to reduce greenhouse gas emissions by 16 billion tons — an amount equal to the combined greenhouse gas emissions of China and the United States — in the next seven years.
With respect to the use of coal, oil and natural gas, those three energy sources still meet about 82% of our primary energy demands, way down from the 86% they supplied in 1997. More importantly, the world is using more coal , more oil and more natural gas than it used in 1997.
