In 2008, the plan was to spread Earth Hour to the rest of Australia but there was an appetite to expand the movement beyond that country’s borders. Canada’s own City of Toronto was the first to sign up and it wasn’t long before 35 countries and almost 400 cities and towns followed suit. It said something compelling to the world: that the climate challenges facing our planet are so significant that change needs to be global.
With the invitation to ‘switch off’ extended to everyone, WWF’s Earth Hour quickly became an annual global event. It’s scheduled on the last Saturday of every March – closely coinciding with the equinox to ensure most cities are in darkness as it rolls out around the Earth.
This year Earth hour occurs on Saturday, March 31 at 8:30 pm.
