What I got from the study is source of your wage and investments have more to do with how much of a high polluter you are than what you choose to do individually. So you could be a high wage earner who lives in a tent and bikes and invests a majority of their money that grows in profit, and that because of the growing investments and employer make you a higher polluter than someone who lives in a huge house and drives suvs and pick ups and doesn't see their net worth grow due to so much of their stuff being financed.

With the money source being weighted this kind of feels more like an industry analysis despite the individual focus with how indirect it is, and based on some of comments here I guess people didn't read the article either not realizing it has less to do with individual efforts like solar or private jets. At least that's what I got from my attempt to understand the study.

Conclusion seems to be more that companies that pollute pay higher wages than a study of direct household pollution.
