Thats whats tripping everyone up, thinking these corporations are off isolated somewhere just producing climate change gases.
No, what theyre producing is what you're buying. When someone says an oil company is responsible for however much greenhouse gas emissions, what they mean is the greenhouse gas emissions when you the customer burn that gasoline in your vehicle. Plus gases emitted processing the oil and getting it to the store for you to buy it.
These companies "taking responsibility" for their emissions would mean halting production of most things you go and buy.
