We asked the big oil and energy companies to sponsor us, we asked the big waste management companies, and the multinational fast food chains, really we spent 18 months asking everyone, but when we told them our bus was rubbish they all said no. All the equipment we’ve have has been begged, borrowed or blagged, but we still need money to pay for visas and permits and ferries so now I’m asking you, to help us get around the world with a sustainable carbon footprint of 2 tonnes per person, per year. We are so tight for cash that I guarantee whatever you donate we’ll put to good use.

"If these wombles make it past my country in a scrap-yard bus running on rubbish, I'll do something clever with my waste, and the energy I use."

Switch your electricity supply to Good Energy using this link and not only will you be supporting the pioneering community of independent green generators, but for every sign up they get they’ll make another donation to help get the bus around the world. It helps you cut your personal CO2 emissions, helps them grow a great business, and helps me get round the world.

Each of the sustainably fuelled expeditions I've done in the past have had a pledge that people have signed up to as a sign of support.
