From the article:
The richest 1 percent (77 million people) were responsible for 16 percent of global consumption emissions in 2019 —more than all car and road transport emissions. The richest 10 percent accounted for half (50 percent) of emissions.
To be a member of the richest 1% of the world you need a net worth of about $800k -- so while the billionaire class is still a massive problem, an even larger problem ecologically is that tens of millions of moderately wealthy people from wealthy nations have massively outsized carbon footprints.
Is that pedal set up up to drive the machine, or is it just for looks?
