The comment you’re replying to makes the case that location matters. It’s arguing against your comparison of total CO2 emissions before you even made that point, and you’re not responding to it, but attacking some imaginary bad argument nobody made.

Your argument is also entirely generic. There is nothing that isn’t “irrelevant in comparison to industry and electrical generation”. Of note, “industry” can be split into arbitrary parts that would all fail your standard of significance. Meat production produces “only a fraction of CO2”. Residential heating, likewise, “produces a fraction of CO2”, and so do lighting, consumer goods, or the entire shipping industry.

Following your logic, nothing really matters, nor can anything be done.
