How about getting the EU to pay restitution to all the people in Central Asia and Eastern Europe for the years of environmental and health damage done due to emission and pollution as a result of the European Industrial revolution? The emissions from the US during the early 20th century which circled the globe many times were pretty damaging too, according to some Russian researchers whilst not forgetting the damage the old Soviet industries did too. So the first world nations must pay the poorer nations now if they want to enjoy less carbon emissions as our developing economies play catch up.
