Earth Hour 2015

Written by Cabinet Office on 26th March 2015

Earth Hour 2015 is taking place on SATURDAY 28th MARCH. 

The Cabinet Office will be showing support for the global campaign aimed at raising awareness of Climate Change by switching off the building lights across the entire Cabinet Office estate, including 10 Downing Street and 70 Whitehall, between 8:30pm and 9:30pm.

What is Earth Hour?

Earth Hour is a worldwide grassroots movement by WWF to unite people to take action for the planet. It aims to engage the mainstream community on a broad range of environmental issues in more than 7000 cities and towns in over 162 countries and territories worldwide.

As the world’s first open-source climate change campaign, Earth Hour has inspired millions worldwide to take action for our planet and get people to use #YourPower to prevent climate change.

What Are We Doing About Climate Change?

The Cabinet Office has been actively reducing its environmental impact in recent years and has successfully reduced its Greenhouse Gas emissions by 56% since 2009 as part of the Greening Government Commitments.

How Can You Make A Difference?

The Cabinet Office would like to encourage you all to take part in the event by switching off lights at home for the hour and by making a pledge to use #YourPower to combat climate change. Ideas include swapping driving for walking and cycling, reducing waste by switching to re-usable bags and reducing energy wastage by switching off unused IT equipment and keeping windows closed when air conditioning is operating.
