Starr and his colleagues analyzed income data across U.S. households from 1990 to 2019 and linked it to emissions generated directly and indirectly from that income. They included income tied to emissions related to the operation of a business, such as from a coal-fired power plant. But they also included income, such as from investments, that supported services or products from those industries.
“As you move up the income ladder, an increasing share of emissions is associated with investments,” said Starr
So this reads almost like an implicit tautology, if I can phrase it like that. Basically, investments are tied to climate emissions -> wealthier people have more of these (because wealth is defined this way, hence tautology) -> wealthy are tied to carbon emissions.
Not useful. I was hoping to read about air travel or large homes or such.
