The charity is hoping to collect 1,000 miles of shoelaces that will be presented along with the petition to Number 10 later this year.
It has also produced a limited-edition Fairtrade organic ‘Cut the Carbon’ shoelace that people can buy to show their commitment to tackling climate change.
Leonardo di Caprio has backed the initiative, along with Katie Leung who starts in the new Harry Potter film. Singer Lemar has already bought a pair of the organic laces.
The laces have been produced to support the coalition of charities in the I Count campaign’s Cut the Carbon March, which runs until 2 October.
The march covers 1,000 miles in 80 days, and over 70 towns and cities. Over 50,000 people are expected to walk some part of the route.
