I would question that very much and guess that overall the opposite is true. I don't however have any data, except national aggregates showing that there's a correlation between GDP and carbon emissions (even before accounting for the fact that arguably quite a lot of the emissions of less wealthy nations come from production of stuff for more wealthy nations). Do you have data?
