Liberal Democrat environment spokesman Chris Huhne says carbon offsetting must be more than just a fashion statement if it is to have a real positive effect on climate change. He argues the long-term objective must be to reduce carbon emissions.
The Green Party's principal speaker Dr Derek Wall highlights the shortcomings of carbon offsetting, concluding it can have only a very limited role in the fight against climate change. He argues any system will need to be regulated by strong legislation to ensure companies do offset carbon emissions as promised.
