You gotta be kidding. The USA has the highest carbon imprint next to China. And despite being the 2nd top offender on the planet we have a dimwit president who won't believe what the majority of scientists say in regard to climate change. I guess because he thinks he has such a "great brain". Only a narcicistic idiot would make that claim. https://www.graphicmaps.com/carbon-emissions-by-country But actually we know he says this sort of crap because he has been bought by the fossil fuel industry. Money talks.
