RESIDENTS are being called on to take part in a lights-out event and help save the planet.
World Wildlife Federation (WWF) is inviting people around the world to turn off their lights on March 23.
Last year, 40 per cent of people in Portsmouth switched off in support of Earth Hour including the Spinnaker Tower and the Civic Offices.
But, Portsmouth City Council is calling on it to be even bigger this year.
Councillor Eleanor Scott, cabinet member for environment and community safety at the council, said: ‘WWF Earth Hour is a significant initiative. I’m happy to support any action that highlights the need to save energy and protect the planet.
‘If residents feel that they would like to join in, that would be wonderful.
‘There’s a great strength in numbers.’
International landmarks, including the Golden Gate Bridge, in San Francisco, the Colosseum in Rome, and the Coca Cola billboard in Times Square in New York, will all be supporting the cause.
Jo Cole, carbon reduction co-ordinator at the council, said: ‘WWF’s Earth Hour is a fantastic initiative, so let’s show just how much we can achieve when we all pull together.’
