Help me win a bet about Co2 please..

[toppstuff]

Evening all - crikey its been a long while since I dropped a post into PH..feels pretty good.

What makes this site special is that there are some clever old sorts on here and I know that the PH collective can come up with some serious answers ( and amusing ones ) to serious questions...

Anyhow, a question for you.

What is better in terms of CO2 output ?( lets just assume that CO2 is important for the purposes of this )

To buy an electric hybrid thingy - brand new and the source of huge amounts of CO2 in its manufacture

OR

Any old V8 where the carbon has already been used up in making it

In other words, is this cobblers on global warming better solved if people simply stopped buying new cars ( and causing massive C02 output in their manufacture ) and instead kept the ones we have, however thirsty and Co2 emitting they may be?

Thanks chaps - I have a greenie colleague to win a tenner from, as I have sworn to him that more Co2 is used making a hybrid car than you'll ever use if you simply kept the old car you have....

I hope I'm right !
