Interesting post over at Green Business News, suggesting an imbalance. In fact there are two possible balances: between green taxes and green spending, and the taxes and the social costs. It would seem neat that the taxes ought to balance the social costs (but they don’t in other areas) but since we don’t know the costs this is hard to do. Certainly the article seems to suggest that the taxes are likely higher than the costs (a theme close to Tim Worstall’s heart), and that even so they have little effect on behaviour. And since the taxes appear to be far higher than the green spending, there is “all stick and no carrot”.
