Earth Hour 2018, let’s turn off lights for the planet!

Earth Hour, the world’s greatest event for the fight against climate change is back on Saturday March 24, 2018. In Paris, like in some 7,000 cities in 187 countries, emblematic monuments turn off their lights to give Mother Nature pride of place.

Earth Hour 2018 is happening this Saturday March 24. This event that makes thousands of peoples’ and thousands of iconic monument’s lights go off. This year, this 12th edition gives Nature pride of place.

Everywhere throughout the world, WWF asks the whole civil society, from citizens to companies without forgetting the local collectivities and governments, to think about how precious our planet is and that it’s vital to protect it. On March 24, WWF will highlight projects to protect the environment: in Colombia, around a zero-deforestation policy by 2020; in Guatemala for preserving sweet water; in India for more sustainable ways of life; and in Nepal for clean and renewable energies.

The UN Convention on Biological Diversity (CBD) chose to make Earth Hour the global event for mobilizing the public around Nature, and this, until 2020, a key year on the subject.

At 8:30 p.m. sharp, Paris Mayor Anne Hidalgo will light the Eiffel tower out in company of Minister of Ecology Nicolas Hulot (yet to be confirmed) and WWF France CEO Pascal Canfin.

Do a gesture of solidarity by coming under the Eiffel Tower or by spending one hour in the dark, like billions of people around the globe!

Initiated in 2007 by WWF to raise awareness, especially those of the decision-makers, Earth Hour first took Sydney into the dark. In 2012, hundreds of million people in about 4000 cities and 126 countries turned off their lights for one hour. This year, we count 154 countries joining the movement. Across the world, lights will be turned off: the Eiffel Tower, like the Empire State Building, the Gizeh pyramids, Rome’s Coliseum, Rio’s Christ the Redeemer, Athena’s Acropolis, the Burj Khalifa tower in Dubai, the Forbidden City… Thousands of prestigious monuments will be turned off for this event.

Beyond the symbolic gesture that turning lights off for sixty minutes is, Earth Hour participants are also invited to join the movement launched by WWF in the world to reduce their greenhouse gas emissions. You need to know that by adopting simple and automatic gestures, like thousands of other people, you can save energy while preserving the environment. And this without harming your daily comfort!

Alright, alright, I see you coming: “it does nothing, an hour of black out will not reduce global warming!” Of course not, but let’s be clear, this global event simply aims at raise awareness so that each and everyone of us can ensure one’s future. The goal is not to switch electricity off but simply turn the light off (or the ones not vital: goodbye red lights and other street lights…) to be seen.

So, this Saturday March 24, 2018, let’s raise our collection awareness.
