The environmental Kuznets curve suggests emissions per capita increases with income, up to a point. Then emissions per capita begin to decline with further increases in income. This theory has supported and also rejected using international data for entire nations. I've not seen a study using income deciles within a nation. I guess it's hard (impossible) to measure emissions per capita in each decile.
