Earth Hour 2021

Earth hour is the moment millions come together for nature, people and the planet – the world’s largest grassroots movement for the environment.

In previous years, iconic landmarks across the world switch off the lights for an hour to stand in solidarity with the planet.

In light of current restrictions and the global pandemic, the focus has recently turned to participation at home. Earth hour is a meaningful hour to feel united with a global community calling for change.

University of South Wales is supporting this year’s campaign. We are committed to taking local action to help tackle global climate change.  On the night, we will be joining millions of homes, businesses and iconic landmarks across the globe by switching off all non-essential lights on our campuses for an hour to stand in solidarity with each other between 8:30pm and 9:30pm.

Did you know 9 out of 10 people who take part feel inspired to do more to protect the planet and want to do more – so it’s over to you.

So why not take part? You can sign up to Earth Hour as an individual by visiting and join the global movement.

This Earth Hour, we turned off non-essential lighting. These images show lights which we had to keep on for safety reasons, so turned green to mark the occasion.
