This Saturday, March 19, at 8:30 p.m. local time, millions of people around the world will celebrate the World Wildlife Fund (WWF)-initiated Earth Hour by turning off their lights for one hour. Participating in Earth Hour is a visible, symbolic action to encourage everyone to make more environmentally responsible choices beyond the event hour and promote climate awareness. For WWF and other participating organizations, it is also an opportunity to garner support for critical conservation projects and drive legislative changes.

Since starting out as a lights-off event in Sydney, Australia, in 2007, Earth Hour has become the world’s largest grassroots movement for the environment. In 2015, a record-breaking 172 countries and territories (that’s 24 time zones and six continents) – oh, and the International Space Station – participated in Earth Hour. That resulted in more than 620,000 actions taken to positively impact climate change, and more than 10,400 landmarks and monuments (think Eiffel Tower) going dark.

Coca-Cola has participated in Earth Hour for many years by darkening some of our buildings and most iconic signs, including Times Square in New York, Piccadilly Circus in London and Kings Cross in Sydney), encouraging employees and communities to participate at home or via a coordinated event, and turning off the lights in office buildings and bottling facilities.

Coke’s participation in Earth Hour supports the company’s belief that climate change is a profound challenge requiring concerted action by government, business and civil society.

As a responsible multinational company, we have a role to play in ensuring we manage our business responsibly. That’s why we’re working to reduce greenhouse gas emissions across our entire value chain by making comprehensive changes in our manufacturing processes, packaging formats, delivery fleet, refrigeration equipment and ingredient sourcing—all contributing to our goal to reduce the carbon footprint of the “drink in your hand” by 25 percent by 2020.

There’s a role and room for everyone to address climate challenges. Earth Hour is one opportunity to get involved. Actions can be simple, like participating in the March 19 event by sharing a candlelight dinner with friends and encouraging others to join, or more extensive such as donating your social feed to Earth Hour 2016 and committing to a daily activity that can benefit our planet. Only through collective actions—big and small—will we truly make a difference in global challenges. The power is yours.
