As we're running out of time we ideally need both to happen, but it's good that green tech is becoming increasingly more financially viable. As a little gem, just about all reports from the SA Tesla battery installation make for simply fantastic reading.
What do you think about going after the things that are actually harmful, instead of following a red herring? I mean, sure, cars should of course be dealt with also, but if you really want to lower carbon emissions fast, then shouldn't we go for the big fish first?
Do you have a link to figures that show this?

Thanks for the link. So it isn't carbon emissions that exceed those of cars but SOx and NOx (which are still a problem).
