Here's a thing the great team at Oxfam have done: an analysis of the investments of 125 of the richest billionaires in some of the world's biggest corporates & the carbon emissions of these investments. These billionaires have a collective $2.4 trillion stake in 183 companies.
The report finds that these billionaires’ investments give an annual average of 3 million tonnes of CO2e per person, which is a million times higher than 2.76 tonnes of CO2e which is the average for those living in the bottom 90 percent of the world.
The actual figure is likely to be higher still, as published carbon emissions by corporates have been shown to systematically underestimate the true level of carbon impact, & billionaires and corporates who do not publicly reveal their emissions, so could not be included in the research, are likely to be those with a high climate impact.
