Ant and Dec are calling on members of the public to take part in ITV's Big Clean-Up campaign, which is supported by CSV.
The presenters of I'm A Celebrity, Get Me Out of Here! are asking people to follow their lead and go green - before the show is filmed, a full audit of the flora and fauna in the part of the Australian rainforest the show uses is carried out to ensure the programme is environmentally friendly.
Now Ant and Dec are encouraging thousands of volunteers across the UK to take part in projects that will improve their own local environment.
The campaign was launched on 5 June, but the event itself will take place on 17 September, which coincides with the UN's Clean Up the World Weekend.
Dame Elisabeth Hoodless, executive director of the CSV, said: "Volunteers can transform local parks, gardens, coast and countryside to everyone's benefit."

Robinson said: "The life and death message on these tags drives home what Marie Curie Cancer Care is about - providing nursing care to ensure terminally ill people have the best quality of life right up until the end."
