Unfortunately, everyone participates and it adds up. If you want to compare such personal consumption like jets, then the rich account for about 15% of the global emissions.

Here’s a chart:

from this report: https://policy-practice.oxfam.org/resources/carbon-inequality-in-2030-per-capita-consumption-emissions-and-the-15c-goal-621305/

The share of total global emissions associated with the consumption of the richest 1% is set to continue to grow, from 13% in 1990, to 15% in 2015 and 16% in 2030.

If you want to include the rich’s capital, which you should, because that has to change:

the bottom 50% of the world population emitted 12% of global emissions in 2019, whereas the top 10% emitted 48% of the total. Since 1990, the bottom 50% of the world population has been responsible for only 16% of all emissions growth, whereas the top 1% has been responsible for 23% of the total. While per-capita emissions of the global top 1% increased since 1990, emissions from low- and middle-income groups within rich countries declined. Contrary to the situation in 1990, 63% of the global inequality in individual emissions is now due to a gap between low and high emitters within countries rather than between countries. Finally, the bulk of total emissions from the global top 1% of the world population comes from their investments rather than from their consumption. https://www.nature.com/articles/s41893-022-00955-z

But if you imagine that the petite bourgeois lifestyle of McMansion in suburbia, cars and driving around everywhere, and the rest of the consumption isn’t contributing, you should read more. Here’s a start: https://www.versobooks.com/books/3691-the-imperial-mode-of-living
