I'm comfortable saying yes to that

Lol. Check your privilege.

A. Do a carbon footprint analysis of your life, if it's above 2,5 tons coe/year you're a net burden on the planet. My country is as well, although considerably lower than the US.

B. It is possible for you to be a paragon of environmentalism and still live in a country with inefficient systems for water, infrastructure, zoning, industry and food production. Not to mention live in a culture of unsustainable lifestyle. Many Chinese or Indian persons are simply too poor to have a major impact on the environment, but their national industrial practices drive up the average pollution to levels comparable to the US (although still lower). Most US people aren't as poor, and also have shitty industry standards, and also the means to change that without losing your standing internationally.

C. Multiple countries are shitty, in fact most of the non-developing world countries are a net burden.

D. As opposed to the other countries at the top, the US has had the economy, data, and access to resources to be able to something about it for generations, whereas most have had half the time and considerable need of modernising.

E. The US is much larger than the other countries, and could with quite simple measures make great impact and help pressure other great polluters.
