This Saturday, businesses, town halls and iconic landmarks across the United States and around the globe will go dark for one hour in celebration of one of the world’s largest voluntary environmental action.

From New York City’s Empire State Building and the Las Vegas Strip to San Francisco’s City Hall and the Golden Gate Bridge, all will go dark as non-essential lights are switched off at 8:30p.m. (local time) on Saturday, March 23 to raise awareness about the environmental impact we have on our planet.

San Franciscans are encouraged to participate by turning off their own lights.  A fun way to celebrate Earth Hour could include dinning by candle light, hosting a “Going Dark” party with your friends and family or going for a walk around your neighborhood and see who in your community is participating. 

“Earth Hour is an annual display of how our imagination can inspire and engage hundreds of millions to focus on the one thing that unites us – our planet,” said Keya Chatterjee, director of international climate policy for World Wildlife Fund (WWF). “In addition to raising global awareness, we are also transforming that excitement into local action to prepare our communities for the impacts of extreme weather and climate change.”

“For years, San Francisco has gone dark in support of Earth Hour to remind our residents that environmental sustainability is critical to our city’s future,” said Melanie Nutter, Director, Department of the Environment. “We are excited to be the U.S. Earth Hour Capital City and are proud of our city’s efforts to protect the planet. We will continue to further cut emissions from energy use, transportation and waste, while showing that it’s possible to have a growing, dynamic economy and lower our carbon footprint at the same time.”

San Francisco is among the leading cities that are showing the world pathways to a low-carbon or a carbon-efficient economy. San Francisco’s green house gas (GHG) emissions reported for 2010 were 5.3 million metric tons, down 14.5% from 1990 levels. These reductions occurred even as the city’s economy grew (gross domestic product up 40%) and population increased (up 11%) during the same 20-year period.

San Francisco has achieved progress reducing emissions primarily by using cleaner electricity, investing in energy efficiency, and recycling and composting more materials, thus sending less waste to landfills.

San Francisco is among the nation’s leading cities addressing climate change and is the 2013 U.S. Earth Hour City Capital. It was selected from a group of 29 U.S. cities participating in WWF’s Earth Hour City Challenge – a year-long initiative recognizing cities preparing for increasingly extreme weather and promoting renewable energy.

San Francisco, along with fellow Earth Hour Cities Chicago and Cleveland, will receive WWF’s Earth Hour Climate Leader Award and $30,000 to support their efforts to engage residents in local climate action.
