On what scale? It seems like the current climate change issues were triggered and amplified before communism was practiced by any state, but while capitalism was actively being used by colonialists throughout the 1800s. Do we count those 100+ years without regulations? If the punishments are minimal, not a single violation of any environmental regulation on a large scale has been appropriately pushed in the leading capitalist state, the US, ever, do those regulations really mean anything to those that are truly the greatest impacts to environment?
