The Great Big School Clean is back for all those schools who feel they can get involved and be part of our million-mile mission. 

This year, we are asking you to pledge the number of minutes and hours your school will litter pick for. Using a slow walking pace of three miles per hour, we will then calculate how many miles you have covered. If 250,000 people across the UK pledged to pick up litter for an hour and twenty minutes each, we would have travelled a million miles – that’s the distance to the Moon and back … twice.

To help you on your litter-picking journey, we’ve designed a useful guide to give you ideas, inspiration and advice to safely plan a clean-up. Don’t forget, participating in the Great Big School Clean is excellent evidence to use when applying for your Eco-Schools Green Flag!
