For the past six years, millions of people around the world have been turning off their lights for one hour to make a collective statement on climate protection in support of WWF’s Earth Hour.  The hope has been, and continues to be, that symbolically taking action for one hour out of environmental concern will drive big and small changes beyond that hour to address climate change challenges.   

Earth Hour, which took place this year in more than 7,000 cities and towns across 152 countries on Saturday, March 23, from 8:30-9:30 p.m. in each of their respective time zones, has inspired a global community and also inspired the Coca-Cola system. Over the years, Coca-Cola has supported Earth Hour by darkening some of its most iconic signs (e.g., Times Square in the United States, Piccadilly Circus in London, and Kings Cross in Sydney), encouraging associates to participate at home or via a coordinated event, and turning off the lights in office buildings and bottling facilities around the system. Many of our employees celebrated at home, including Wendy Clark (our Senior Vice President of Integrated Marketing Communications and Capabilities) who played games at home by candlelight with her family for the hour.

Earth Hour

Our Coca-Cola sign in Picadilly Circus went dark for Earth Hour. The Company also used the sign to promote Earth Hour in days leading up to it.

As lights went off around the world for Earth Hour, I hope many proverbial lights went on regarding the urgency of implementing climate protection measures. Earth Hour serves as a reminder that we all need to strive toward a more sustainable world, not only for one hour, once a year, but every day. And, WWF is hoping that rings true across the countries that activated as they have an entire post-Earth Hour campaign to drive action and awareness of climate change. Check it out at

At Coca-Cola, we recognize climate change as one of the most critical challenges facing the planet, with potential impacts on biodiversity, water resources, public health and agriculture. Thus, we have been working to make measured changes in our operations and value chain to improve our overall efficiency and minimize our impact. If you’re interested in learning more about our efforts, you can read about it in our most recent Sustainability Report.
