Green Britain Day will take place on July 10 and aims to get more people involved in measures aimed at tackling climate change.

The centrepiece of the campaign is a television advert that uses the “recycled footage” technique of recent EDF campaigns using clips of the 1948 Olympic in London, including featuring Fanny Blankers Koen, who won four gold medals at the Games and Emil Zatopek, the 10,000 metres champion.

EDF Energy is the sustainability partner of London 2012 and, as insidethegames reported earlier this week, the campaign is also being supported by Victoria Pendleton, the Olympic cycling sprint champion.

A dedicated site, www.teamgreenbritain.org, has been created and developed in association with the Eden Project and Global Action Plan.

The aim of the project, it is claimed, is to "leave a lasting, green legacy after The London 2012 Olympic and Paralympic Games".

It will suggest ways people can get involved on July 10.

More than 450 schools have signed up to be part of activities, as part of EDF's online 'POD' educational resource; 1,000 more have downloaded materials to help them 'do something green for the team' on the day.

There will also be 20 community events running across the UK.

EDF has also partnered with radio group Global Radio to create a number of sustainability-themed events on the day, which will conclude with a concert at the Eden Project in support of Prince Charles’ Rainforest Project, and featuring Paul Weller.

Sebastian Coe, the London 2012 chairman, said:"'London 2012 is all about using the power of the Games to inspire change and it's fantastic to see EDF Energy, the first sustainability partner of London 2012, taking this on in their activation.

"The Green Britain Day campaign is a great way for people to come together and make a difference.

"Sustainability underpins our planning for the Olympic Games and Paralympic Games.

"It will be a key part of our legacy and Team Green Britain will, I hope, grow as we head towards 2012 and live on after the Games have gone."
