Organisers of Earth Hour have cancelled the event due to a rainy forecast.

The glum weekend forecast was due to be held on Sunday after being postponed from tonight but the decision to cancel the event altogether was made last night.

'In line with ensuring we were delivering a sustainable event we had to consider the risk of food vendors organising food that could have gone to waste if rain occurs and participation was low,” says sustainability advisor Michelle Elborn.

'In addition we have considered the safety of the stage and equipment. This was not a light decision and all the organisers are disappointed, in-particular to not be screening the Enspire youth video finalists.”

The free event's ethos was to bring the community together to celebrate Earth Hour, which is an international event to raise awareness and stimulate action towards caring for the planet.

'Earth hour is a great opportunity to raise awareness on local environmental issues – and inspire local community action,” says Michelle.
