Oxford’s famous landmarks are set to be plunged into darkness in a global electricity shutdown to raise awareness of climate change.

Earth Hour 2009 on Saturday, March 28, will see 900 cities across the world turn off non-essential lights and appliances for 60 minutes.

In Oxfordshire, the city and county councils have promised to take part in the switch-off between 8.30pm and 9.30pm.

The Midcounties Co-operative, Oxford Brookes University and Oxfordshire Primary Care Trust will also join in the blackout.

City councillor John Tanner, board member for a cleaner, greener Oxford, said: “Oxford City Council is supporting WWF's Earth Hour because everyone in Oxford needs to reduce their carbon footprint. Switching off those unnecessary lights and electrical appliances really does make a difference.

“I would encourage you all to switch off your lights and appliances for one hour to show your support to Earth Hour.”
