I don’t see how taking advertising dollars from fossil fuel companies affects anything. It’s not like we’ll suddenly stop burning carbon if we stop oil and gas companies from advertising. The demand for oil will still be there. We need to make alternative energy sources cheaper than fossil, then demand will plummet.
We could do a lot by removing the trillions of dollars in subsidies which those companies receive, however. If the price of oil went up, people would scale back usage and alternatives would have an easier time, both outcomes which the fossil fuel industry has spent a considerable amount of money preventing.
