The linked IPCC report is even more specific. The 100 companies cited are all involved in fossil fuel production. So as long as you don't use fossil fuels or consume anything made or transported with fossil fuels, it isn't your fault at all.

very often, but not always. they do research and dev manufacture and synthesis, they do global commerce and manufacture substances that feed into other industries.

two big problems:

throwit away and buy another habit.

Evolution of fossil fuel compared to consumption. without formulating a thesis, it takes a long time for natural processes to yield "fossil fuel" in terms of millions of years if dating by isotopic abundance is not fudged. We are burning/using fossil fuels and releasing what was apparently captured over millions of years, over a span of [a couple hundred?] years. there is a decompression problem here, we dont have the slack space in our ecosphere to allow this highly concentrated resource to be opened up full bore like we have done.

I only drive maybe 180 miles a month, and go on a flight once a year, so I should be among the last people to blame.

Those people who put their travel porn pics on Instagram should be among the first :)
