The report assesses the consumption emissions of different income groups between 1990 and 2015 – 25 years when humanity doubled the amount of carbon dioxide in the atmosphere. It found:
The richest 10 percent accounted for over half (52 percent) of the emissions added to the atmosphere between 1990 and 2015. The richest one percent were responsible for 15 percent of emissions during this time – more than all the citizens of the EU and more than twice that of the poorest half of humanity (7 percent).
