Earth Hour 2022

Switch off your lights for Earth Hour26th March 8.30pm, local time

Every year, at 8:30 pm on the last Saturday of March, millions of people across the world show their support for our planet, raising awareness of nature loss and climate change – the two biggest threats facing our one home.

Started by WWF and partners as a symbolic lights-out event in Sydney in 2007, Earth Hour is now one of the world’s largest grassroots movements for the environment. Earth Hour engages millions of people in more than 190 countries and territories, switching off their lights to show support for our planet.

2022 presents an incredible once-in-a-decade opportunity to push world leaders into action. Later this year, world leaders and representatives from all over the globe will be attending a crucial United Nations conference for nature and biodiversity – the the UN CBD COP 15 (United Nations Convention on Biological Diversity 15th Conference of the Parties) – Kunming, China.

The state of nature and biodiversity will be the focus for this conference, and global plans will be made for the next 10 years – decisions that will affect not only the next decade, but our future and well-being for many years to come. With enough public pressure, this could be the conference where we secure an ambitious global commitment – similar to the Paris Agreement, but for nature – to reverse the loss of nature and biodiversity by 2030.

And why 2030? Nature is not only our biggest provider – it’s also one of our strongest allies against the climate crisis. Unless world leaders urgently step up their efforts to protect nature, global temperatures could rise above the 1.5 degree Celsius limit set by the Paris agreement as early as 2030, a decade earlier than previously expected. Any further increase in temperatures could mean irreversible damage to our planet.

With supporters in over 190 countries and happening shortly before the UN CBD COP 15, Earth Hour is an opportunity to put the spotlight on this crucial conference for nature, building the global momentum needed to pressure world leaders into action.

Today, Earth Hour aims to increase awareness and spark global conversations on protecting nature not only to combat the climate crisis, but to ensure our own health, happiness, prosperity and even survival.
