Earth Hour Vancouver 2013 Could Win Global Title

Vancouver is going head to head with five other cities for the title of 2013 Earth Hour Capital, an award to recognize cities that take innovative action on climate change.

Earth Hour is a global campaign organized by the World Wildlife Fund (WWF) every year that asks cities to turn out the lights for an hour as a way of showing concern for the environment.

This year's Earth Hour happens March 23 from 8:30 p.m. to 9:30 p.m. "wherever you are in the world," says the WWF website.

Vancouver was named the Canadian champion of the WWF's 2013 Earth Hour City Challenge over B.C. cities Surrey and Colwood in a contest for cities switching to renewable energy. That includes energy sources such as solar and wind that do not generate significant greenhouse gas emissions.

The WWF praised Vancouver's focus on urban development and local food systems in a news release.

Vancouver is up against cities including Uppsala, Sweden and Cochin, China for the global title which will be decided through an online vote.

UPDATE - March 19, 2013: Vancouver won the title of Global Earth Hour Capital 2013 at a World Wildlife Fund awards ceremony in Malmo, Sweden. Voters from around the world also selected Vancouver as the People’s Choice winner out of the 17 cities who were national WWF Green City Challenge finalists.
