Who's the Greenest?

Watch Video: So, who is the greenest volunteer? >

With just a few days left on the dump, Rob is keen to make the group's thoughts turn to life out in the real world. He wanted to find out how green the group thought they were. He asked them to arrange themselves in order from greenest to least green. Selena was placed first, with Lawrence in second place and Jermaine judged to be the least green.

Some surprises in store

To find out the actual truth, Rob asked each member of the group to complete a simple carbon calculator questionnaire. This information, together with data gleaned during the application process, was used to calculate how many tonnes of carbon they had each been responsible for emitting in the previous year.

The results were a real shock in some cases:

Despite coming top, Lawrence vowed to continue doing more to cut his carbon emissions still further: 'Since coming on the show I've realized I can do more to cut down my carbon emissions. Even though I'm the best, I'm still not sustainable. I'd like to reduce it by a tonne every 6 months.'

When Rob explained to him that 5 of his 7.5 tonnes of carbon were actually nothing directly to do with him but were used up on his behalf by government services, he looked perturbed: 'I am gonna start petitioning the government to try and reduce that cos I don't think its fair that I'm suddenly given 5 tonnes for just existing in this country.'

The biggest surprise announcement was second place, which went to Aaron. He looked delighted at his unexpected eco-credentials, while most of the rest of the group looked shocked. But it was no coincidence that the two people with the lowest carbon emissions were both hard-up students who had to rely on public transport and took few holidays.

Selena looked perturbed at her fourth place as she had envisaged being the greenest. But Rob pointed out that because of her job she had to drive about 500 miles a week. And even though her car had been converted to run on LPG, it was still a large 3.2-litre 4x4. In actual fact, she would probably emit less carbon by driving a small petrol or diesel car.

Sylvia was also unhappy with the results. Despite being very aware of green issues, and trying hard in many areas of her life, she was down in 8th place with 18.4 tonnes. She quickly realised it was the flying for her work that let her down: 'I actually feel a bit embarrassed. I'm going to go home and offset all my carbon emissions for the last year and keep doing it,' she vows. But Rob points out that this is by no means a magic solution. The only real answer is for us to emit less carbon in the first place, so the truly sustainable solution would be for Sylvia to fly a lot less.
