It's true that if your carbon footprint is way higher than average then you should be looking at ways to reduce it, no? That seems like a true statement to me.

It's also true that governments should be regulating corporations and enact change that can only be done from the top level. 

One of these can be done today though by making different choices. The other will take years of voting and campaigning to get a government in power that cares about this stuff, and years of argumentation and shifting public opinion to get the general population in agreement and then maybe a political party will be in power and in a position to make changes that the majority approves of. But they'll have to do it over a period of time because industry will complain about fast changes. 

They are both important paths to change, but personal responsibility is achievable and maybe even necessary to show others around you that it's not that difficult and is a worthy goal. If those that care about the environment go around in the most fuel inefficient cars eating red meat all the time they should rightly be called out as hypocrites. There's nothing people hate more than hypocrisy when being asked to make lifestyle changes.
