Richard Hammond's GreenTraveller site is a new forum for green travel

Travel has been one of the main issues of the recent green debate and aviation has been at the core of concern. In some circles, mentioning you plan to travel to Edinburgh or Paris by plane is enough to draw gasps of horror. But for every traveller who agrees with George Monbiot that we should put an end to flights today, there is one who thinks the UK's emissions from flights are so small as to be almost negligible. And in the middle, there are many more who don't really know what to do for the best.

Richard Hammond's new GreenTraveller blog should prove a good debating forum for this middle ground. Hammond, who writes on green travel for the Guardian, says travellers are increasingly looking for greener options and are unsure about the best choices.

The blog features articles he has written for the Guardian, addressing eco and ethical dilemmas such as 'Is it OK to go to Antarctica?' and 'Is it OK to hire a mountain porter?' To answer the questions he turns to experts in the field to see what they have to say. The blog gives readers the chance to add their voice to the debate, and to raise their own questions about eco-tourism.

Unsurprisingly, one of the posts already on the site is about flying, with Hammond addressing the question 'Is it OK to go on a responsible holiday when it involves flying?' The response from his experts - George Monbiot and the Rough Guides founder, Mark Ellingham - is an unequivocal no. But Hammond says: "There are six sides to the argument and everyone has an idea about what to do, from cutting down on flights to looking at ways to make the flights you take greener." Whatever side you're taking, there's now another forum where you can have your say.
