It's been billed as the "Green Budget". Here are some of Darling's green announcements:
1) The Government are considering raising the carbon emissions target, for an 80% cut in emissions by 2050.
2) Legislation to be introduced for plastic bag charging.
3) New £26 million fund to help householders reduce emissions.
4) Reform of vehicle excise duty (including re-banding) to encourage consumers and manufacturers to buy/make less-polluting cars.
