Yesterday Austria's government decided something they call "Verschrottungsprämie", a scrapping bonus for those who give there old cars away. You better name it a "New Car Candy": You'll have to replace your old vehicle by a new one to get the bonus.
If you are interested in some arguments against the scrapping bonus, you can find a statement of radlobby.at in German here.
The VCÖ (Austrian Traffic Club) has started an initiative to give a greenie bonus of 100€ for purchasing a bicycle or an annual ticket for public transport. I like this idea and I'm hoping for big support.
