Every year, millions participate in Earth Hour by turning off their lights for one hour. But this event is about more than just saving electricity; it’s a powerful opportunity to inspire change.

This year, Earth Hour falls on Saturday, March 22, at 8:30 p.m. local time. By simply switching off your lights, you’re making a statement against climate change. Every little bit counts, and that hour can lead to broader awareness and action for the environment.
Earth Hour started in 2007 in Sydney, Australia, thanks to the World Wildlife Fund (WWF). Since then, it has grown, with Canada adopting the event in 2008. But as we’ve celebrated this movement, the planet has faced significant climate challenges. Last year set records for the hottest temperatures globally, surpassing 1.5°C above pre-industrial levels for the first time. Extreme weather events have been on the rise, affecting communities worldwide. In fact, 2024 was marked by a staggering 15 consecutive months of record-breaking temperatures.
According to a recent study by the National Oceanic and Atmospheric Administration (NOAA), 2024 continued to show alarming climate trends with increasing heatwaves and severe storms. It highlights the urgency for collective climate action. As temperatures rise, so do calls for effective measures to combat the climate crisis.
Kate Landry, senior manager of community action at WWF-Canada, points out that Earth Hour now goes beyond just turning off lights. The movement has fostered campaigns and events that encourage people to take various actions for the planet. Whether it’s participating in local clean-ups or advocating for sustainable policies, Earth Hour serves as a springboard for long-term change.
On social media, this year’s Earth Hour is buzzing with engagement. Many users are sharing their plans and highlighting how they will participate. You can find hashtags like #EarthHour2025 trending, reflecting the anticipation and commitment of individuals and communities to make a difference.
Participating in Earth Hour is more than just a moment of darkness; it’s a chance to reflect on our responsibility to the Earth. As we take this hour, let’s also remember that lasting impact comes from ongoing actions and conversations about sustainability.
