Gordon Brown's budget today was a very poor effort all round and involves quite a bit of trickery. The so-called 'green' measures were on a pretty small scale eg in 1999 'green' taxes amounted to 9.6% of total taxation but after this budget will still only be 7.5% (figures from the BBC), so not even back to where we were 8 yrs ago!
