A new report found that a "polluter elite" is responsible for producing as much carbon emissions as 5 billion people.
140k/yr USD is still well within the class of people who care. Basically every doctor in America falls into that category.
There's this temptation to believe that global warming is only caused by a very small group of unrepentant greedy assholes, when the fact of the matter is that it really is a systemic issue caused by essentially everyone in a moderately developed country.
Sure, most emissions can be traced to a handful of companies, but we've quite recently seen what happens when the price of gas spikes even a little bit and people lose their god damn minds. Companies go for cheap polluting practice because consumers demand everything be as cheap as possible.
That's income though. The rich don't have income, they have property. Top 1% wealth is more like $13 million.
That site also says top 1% income is more like 400k (individual) to 600k (household). (Edit: though those are us numbers not global.)
It should be noted that the category of 'world's richest 1%' includes quite a lot of Americans. If you've ever flown for a vacation, there's a decent chance you're included in that category. This is not the Musks and Bezos and Gates of the world; it's the doctors, lawyers, tech workers, and middle managers.
They also own almost all of the other carbon emitting facilities & vehicles. So they’re responsible for most of the carbon emissions.
