Yes and no. It is definitely true that companies aren't just burning coal for the fun of it, but the primary problem is that companies have no (economic) incentive to use processes that are less environmentally damaging. In fact, given that we know for a fact that fossil fuel companies knew about global warming in the 70s and tried to hide it from the public[1] shows that they have a profit incentive to stop research into alternatives. Getting those 100 companies to cut their emissions even down by 50% (or spend significant amounts of their massive profits on renewable energy research) would have a larger impact than any individual action you could attempt (and fail) to get the public to do. https://www.theguardian.com/sustainable-business/2017/jul/10/100-fossil-fuel-companies-investors-responsible-71-global-emissions-cdp-study-climate-change https://www.theguardian.com/sustainable-business/2017/jul/10... is an article on the figure if anyone is interested.
