Earth Hour for Cities

What your city can do for Earth Hour:
Help us make a statement for our planet seen around the world.

At 8:30 p.m. your local time on Saturday, March 28, 2020, millions of people around the globe will turn off their non-essential lights for one hour during Earth Hour to show solidarity for and a strong commitment to climate action and protecting our planet.

From the beginning, cities and towns across America have enthusiastically embraced Earth Hour—turning off lights in government buildings and urging their citizens to participate. This single act is provoking discussion and is helping to create the change we need to reduce our environmental impact.

Earth Hour is a great opportunity for your local government to demonstrate your commitment to the environment, showcase your existing environmental work and engage with your communities. This year, we're asking everyone to turn off your lights and join us in a global movement to recommit to nature by calling for better protection of our wildlife, rivers, oceans, forests and climate. Here are some tips for how your city can support Earth Hour 2020:

  • Sign up and show you support a sustainable future for our planet
  • Switch off non-essential lights at 8:30 p.m. your local time on Saturday, March 28, 2020
  • Spread the word and help us reach as many people as possible. You can promote Earth Hour to your staff, suppliers and contacts through your website, newsletters, social media channels or any other way you like! 
  • Encourage other landmarks and local groups in your city—schools, workplaces, streets, communities, restaurants and bars—to plan their own Earth Hour events
