The true solution to travel related environmental damage is to cut down on travel, which most of us could do easily. The problem is there are a lot of people like me who love to drive big gas guzzling cars just for fun, or to jump on a jet when we could as easily video conference or vacation nearer home. There may come a time when we (or more likely our grandchildren) have to be denied some basic rights in order to maintain our civilisations.
