The Half-Green Prince

How green is Prince Charles? Answer: could do better. Charles does seem to be the most outspoken of the blue-blooded bunch on green matters, though sadly Prince William has abandoned the idea of a career in the environment he once mentioned a few years ago to join the army. Charles told the BBC's Today programme that climate change is the biggest threat facing mankind - yet he clocked up over 77,000 miles of overseas travel last year, much of it in chartered planes.

An article in the Guardian on his green credentials (which left me wondering exactly how Charles was supposed to have had one-seventh of a child) gives him just two out of ten for travel (private cars, running three big stately homes and pledging to oppose new wind farms) but top marks for food and farming - including organic farming and conservation at Highgrove and promoting school vegetable gardens. Charles is as outspoken on green matters as others in top positions are silent, and certainly gets important publicity for climate change and organic farming.

Should Charles, who once said he could say what politicians can't, put his (our) money where his mouth is? You can share your climate change concerns on the BBC talkboard.
