That is the point. But there are multiple players in the system, each can point their finger somewhere else. The Western consumer purchases vehicles from whatever selection is manufactured. Presumably advertising works, if it didn't it wouldn't be run. What is available, what is advertised? Lots of gas guzzlers. Why do the manufacturers make them? Some people want them. Some don't. Consumers also want to consume. So more ships fling more goods and cruise passengers around the globe with super bad emissions. Consumers want to fly everywhere, same thing. Consumers wouldn't consume if the thing to consume wasn't offered, but it is. (I think of the real estate finance collapse in the USA circa 2008 as another multi-party problem, everyone supporting or enabling someone else in it.) He is not wrong. He is absolutely right. Who is going to give up their Amazon prime to reduce oil demand? Everyone will point out how insignificant contribution X will be to the total and avoid doing it.
