I don't necessarily buy this and am too lazy to look deeper into it. But I like your attitude, good luck.

Edit: where is this 6% number coming from? https://ourworldindata.org/ghg-emissions-by-sector

Chemical & petrochemical (3.6%): energy-related emissions from the manufacturing of fertilizers, pharmaceuticals, refrigerants, oil and gas extraction, etc.

1. Incredible line.

2. That 6% is based on the most recent IPCC report which estimates 1.4 GT from HFCs, and another ~1.4 from CFCs+HCFCs, so 2.8 total. OWID seems to get its data from climatetrace, I haven't dug into their data, but if I'm reading that correctly it looks like that is only energy usage from manufacturing, rather than direct emissions of the gases. Looks like maybe this breakdown just ignores refrigerants, which is unfortunately common.
