WWF's Earth Hour returns to London (and indeed the whole planet) this March, plunging us temporarily into darkness.

You probably know the Earth Hour drill by now — it's been running since 2007 after all. Switch your lights off for an hour on a Saturday evening to show your dedication to caring for the planet.

Landmarks including the BT Tower, Harrods, the Royal Naval College, Tower Bridge, Southwark Cathedral, Mansion House, Barbican, the Gherkin, St Paul's and the Royal Opera House have taken part in previous years, making for an unusual view of the London skyline. Only non-essential lights are switched off, and street lights remain on for safety reasons — though in a city like London, that means rather a lot of bulbs remain on, and it rarely reaches anything close to pitch black. Check back on the Earth Hour website or with individual venues to find out what's going dark this year.

The WWF is encouraging people to go one step further for Earth Hour 2024, and give 60 minutes of their time to doing something positive for the planet. Planting a tree, going litter picking, or cooking a sustainable meal during Earth Hour are among the suggestions. Check out the Give an Hour for Earth section of the website.

Earth Hour 2024 takes place Saturday 23 March at 8.30pm.
