It groups by country rather than income level but, reading between the lines, it seems to me almost certain that the bottom 85% (in income) of people emit more than half of the global total.
BTW it is important to consider that a large fraction of the emissions from countries like China and India are in the service of consumption in wealthy western countries. But, I googled, and even in a famously export-heavy country like China, exports only account for 17% of the GDP.
