Nature not only provides us with all the things we need to live - from the air we breathe to the water we drink, and from the shelter we need to the economy we rely on - but also makes our lives better. However, its growing loss puts this all under threat. This Earth Hour, join millions around the world to turn off the lights and speak up about why nature matters. #Connect2Earth

For the past 10 years, people around the world have come together every Earth Hour to support efforts to tackle climate change. And, together, we have created a powerful movement that helped deliver strong global commitments to tackling this threat.

Climate change remains a big challenge for us all. But another urgent threat now demands our attention: the loss of nature. These two combined threats mean we must act - and now.  

It all starts with Earth Hour 2019

WWF’s Earth Hour 2019 is an amazing opportunity for you to start changing the planet for the better - join millions around the world to turn off the lights and speak up on why nature matters. #Connect2Earth. Earth Hour takes place on Saturday 30 March at 8.30pm local time, wherever you are in the world. Find out more at earthhour.org.

Earth Hour Cambodia

WWF-Cambodia started Earth Hour since 2012 and this year Earth Hour 2019 will be celebrated on 30th March 2019 from 5:00PM onwards at AEON Mall 2 Sen Sok City.

This year Earth Hour's theme is #Connect2Earth.

The campaign aims to shine spotlight on the importance of natural resource protection and biodiversity conservation. We believe that everyone can contribute to the protection of the environment and the Earth, which is our shared home. We can #connect2earth by taking simple actions such at switching off lights, turning off cars or water taps when not in use. 

Biodiversity and climate change are closely interconnected. Thus, protecting water, forest, and wildlife can help us to reverse the trend of climate change. Together we can protect #wildlife and #forest by not eating bushmeat and not using luxury wood. We only have one Earth and are utterly dependent on it for our survival and well-being.


How you can participate:

  • Switch off lights at home for one hour from 8:30PM to 9:30PM on 30th March 2019

  • Come to enjoy the concert, art performances, and candle lighting on 30th March 2019 at 5:00PM onwards at AEON Mall 2 Sen Sok City

  • Share information about Earth Hour 2019 as well as other activities about environmental protection and natural resource conservation to family members, friends, colleagues

  • Visit WWF-Cambodia Facebook page and Earth Hour's website (https://www.earthhour.org/) and Earth Hour's Facebook page (https://www.facebook.com/earthhour) to get updated information about Earth Hour as well as other information about evironment.

A new role for Earth Hour


Starting as a symbolic lights out event in Sydney in 2007, WWF’s Earth Hour has grown to become the world's largest grassroots movement for the environment. It’s been more successful than we ever imagined - inspiring individuals, communities, businesses and organizations and reaching more than 180 countries and territories in 2018.


While climate change remains a vital issue for our planet, we believe the spotlight must also focus on the accelerating loss of nature and the threats this poses to us all. We need to build a movement for nature, to generate and galvanize attention in a similar way to what was achieved with the 2015 Paris agreement on climate change. And we need the Earth Hour movement to play a key role.


This Earth Hour, we will invite our hundreds of millions of supporters and global networks to spark never-before-had conversations on the loss of nature around them. We need to reach more people than ever, helping them to understand why nature is so vital for their health, well-being and prosperity, and why we need urgent action.


Over the past decade, Earth Hour has helped bring climate action to the top of the agenda. Now is the time for us to build on this to create a broader movement for nature.
