Earth Hour 2023 - Can an Hour change the world?

Posted on 21 Mar 2023
Since our beginnings in 2007, Earth Hour has been known for the “lights off” moment, with individuals from around the globe switching off their lights to show symbolic support for the planet and to raise awareness of the environmental issues affecting it.

More than 15 years later, we are now at a tipping point with our climate and nature crises, putting at risk the fate of our one home and all our futures. We are on course to breach by 2030 the 1.5°C global temperature increase limit set by the Paris Climate Agreement, and nature - the source of our very livelihoods and one of our biggest allies against the climate crisis - is also under severe threat,  facing alarming and unprecedented rates of loss globally.

The next 7 years are therefore crucial to all our futures - we have to stay under the 1.5°C climate threshold to avoid irreversible damage to our planet, and we need to reverse nature loss by 2030, ending the decade with more nature and biodiversity than we started, not less.  To make this happen, individuals, communities, businesses, and governments must all urgently step up their efforts to protect and restore our one home. 

With this 2030 goal in mind, we too must step things up. So this year, we’re breathing new life into Earth Hour - our brand, our work, our message, and our mission - creating the Biggest Hour for Earth. How? By calling on our supporters across the globe to switch off their lights and give an hour for Earth, spending 60 minutes doing something - anything - positive for our planet.

With presence in over 190 countries and territories, we can use the power of the people to turn a single Earth Hour into thousands and millions of hours of action and awareness, creating a domino effect of impact that continues well beyond the 60 minutes. Amidst our increasingly divided and polarized societies, the Biggest Hour for Earth becomes a precious moment of unity, reminding the world that our one shared home needs our help and that we all can - and must - play a part in protecting it.

Can an Hour change the world?

  • On 25th March 2023 at 8.30pm, as landmarks and homes across the world switch off their lights, we are asking you to spend 60 minutes doing something - anything - positive for our planet.
  • Just 60 minutes? Yes, just one hour. It may not seem like much, but the magic happens when you, and those like you in Asia and Africa, North and South America, Oceania and Europe - supporters in over 190 countries and territories - all give an hour for our one home, creating the Biggest Hour for Earth. 
  • By doing so, this Hour can shine an unmissable global spotlight on nature loss and climate change, and the need to work together to secure a brighter future for people and the planet. 
  • It could compel millions to act, and make millions more take notice. It could unite cities, countries, continents, showing what we all have in common, and what we stand to lose. It could remind us that time is precious - but that we are powerful - inspiring us to make all other hours count. 

Could an Hour change the world? It’s a start, and it’s up to us. 


Earth Hour 2023 in Central and Eastern Europe - One home.One Future:




This year, WWF-Slovakia is celebrating Earth Hour with the designation  of a municipal protected area on the Hron River which has been created instead of a planned dam. The almost five-kilometer area of Beňadické alúvium Hrona was established by the Municipality of Hronský Beňadik in February 2023. Originally the construction of a small hydropower plant was planned but the local community and conservationists protested against its construction. Thanks to their joint efforts, a protected area will finally be created. This is the very first general river protected area in Slovakia.

On Earth Hour day, 25th March 2023, the WWF-Slovakia team together with volunteers will place signs in the terrain to mark the protected area in which the Hron River will continue to flow freely. Together with the local community, the village of Hronský Beňadik, the Slovak Fishermen's Association, boaters and volunteers, they will clean the banks of the river from waste. The aim of this year's Earth Hour is, among other things, to inspire people to dedicate themselves to any activity for the benefit of nature, to step out of their routine, and to live more responsibly towards nature in the long term.


“What if every person on the planet decided to do something small to protect the environment every month? However small, but be practiced methodically and for a longer period”.

For #EarthHour2023 , WWF-Romania  is launching a special challenge:

Stop your daily routine and dedicate an hour to the Earth every month. An hour in which, together with family or friends, you can do something related to the protection of nature: cook with local ingredients, renew an old blouse, recycle, plant a tree. ”It's not much, it's not difficult, but if we gather many people conscious about nature, we have a chance to make a change. We have a chance to stop the degradation of nature and help it become even more resilient. For our well-being and for future generations!

Together, we can turn a single Earth Hour into thousands and millions of impactful actions for our common home!

The symbolic gesture of turning off the lights for an hour on 25th March 2023 at 8:30 p.m. for 60 minutes in Bulgaria  will be supported by a special WWF-Bulgaria campaign and event:

We've lost 69% of our wildlife, but we have a chance to save the rest. Their home. Our home. You don't need to be an expert in forest science or know how to save wild animals to become their most dedicated protector. You can help them even from a distance.

There is no better occasion than Earth Hour  - the largest global initiative dedicated to the protection of our common home - planet Earth. With their donations, wildlife protectors give us even more confidence that we will achieve the ambitious goals we have set for ourselves. Become a protector of the wildlife in Bulgaria. 

Take part in the Earth Hour charity Quiz event on the 25th of March in Sofia.
