Maybe I was unclear what I meant, I didn't mean, that gas taxes are in general irrelevant, but that this is not the place where currently change is needed.

The fact, that the gov speaks about houses is no contradiction to that, but a support. In general I'm not unhappy with the gov's environmental policies, I was talking only about what Mr. Tiefensee said. And it is of course no support for your statement that the 'ecological movement' is addressing all the issues, as the current gov doesn't contain people I would count as part of that, while the previous gov did contain such people, and obviously did not deal with the house insulation issues in a way, that only small changes would be enough now.
