An unprecedented 187 countries and territories came together for WWF’s Earth Hour on Saturday 25 March to take a stand for climate action. More than 3,000 landmarks switched off their lights and millions of individuals, businesses and organizations across seven continents stepped forward to change climate change. Online, #EarthHour and related terms generated over 1.1 billion impressions in 24 hours, trending in at least 30 countries worldwide.
This year’s event marked the tenth anniversary of the Earth Hour movement, which started as a one-city event in Sydney in 2007, and comes at a time when the need for climate action is greater than ever. 2016 was the hottest year on record and ambitious action is needed by governments, companies and people, their biggest stakeholders, to meet the targets set in the landmark Paris Agreement that entered into force in November last year.
Across the globe, Earth Hour is inspiring and mobilizing people to be a part of the climate action our planet urgently needs at a personal, community and national level.
