Earth Hour: 27 March 2021

What is it?

Earth Hour is a global movement, which brings millions together across the world to call for greater action on climate change. Each year, hundreds of millions of people around the world switch off their lights and organise events – at home, in their community or in their towns or cities – to show they care about the future of our planet.

Each year millions of people across the world take part to send a clear message of support for climate action. From the Sydney Opera House and the Eiffel Tower to Buckingham Palace and Edinburgh Castle, cities, towns and communities like yours across the world switched out their lights and came together for an hour, to join a global show of support for action on climate.

Why take part?

Right now we’re up against the biggest environmental threats that our generation, or any generation, has ever faced.

Wildlife we love, like elephants, turtles and polar bears, are at risk from the effects of climate change, pollution & over-consumption.

The damage has been shockingly fast. Over the last 25 – 30 years:

  • 80% of freshwater species have declined
  • Over 50% of populations of land species have declined
  • 40% of our forests have disappeared to agricultural land with 15 million trees lost each year just for soy production
  • 1 in 6 of the planet’s species are at risk of extinction from climate change

How we’re helping fix it:

  • Working with international governments to accelerate the shift to a low-carbon economy and drastically reduce emissions from burning fossil fuels like coal, oil & gas
  • Restoring & protecting important habitats
  • Addressing our food systems to ensure we’re farming sustainably, reducing waste and consuming responsibly
  • Helping poorer countries cope with their changing climate
  • Encouraging everyone to make sustainable lifestyle choices such as the energy in their homes, transport options, sustainable diets and more…
