Let’s keep the momentum going ’til Earth Hour 2023 next year – 25 March, 8:30 pm local time! After all, Earth Hour isn’t only about committing for one hour on one day – it’s about committing every day to take care of our planet and each other:
Started in 2007 by WWF and partners as a symbolic lights-out event in Sydney to raise awareness of climate change, Earth Hour is now one of the world’s largest grassroots movements for the environment. Held every year on the last Saturday of March, Earth Hour engages supporters in more than 190 countries and territories, all taking action to ensure a brighter future for people and the planet.
Earth Hour has also gone far beyond the symbolic action of switching off – it has become a catalyst for positive environmental impact, driving major legislative changes by harnessing the power of the people and collective action.
Earth Hour is open-source and we welcome everyone, anyone, to take part and help amplify our mission and impact.
