As the climate crisis grows increasingly severe, each Earth Day carries greater importance. First established in the U.S. in 1970, this annual event—now marking its 55th anniversary—unites millions worldwide to support environmental protection and emphasize the urgent steps needed to save our planet.

Earth Day 2025 arrives as the UN’s World Meteorological Organization reports that 2024 saw over 150 “unprecedented” climate disasters, including six tropical cyclones in the Philippines, extreme heatwaves across Europe, East Asia, and the Middle East, and severe flooding in Italy, Brazil, and Senegal. Additionally, 2024 was the hottest year ever recorded, with global temperatures surpassing 1.5°C above pre-industrial levels for the first time.

Despite the many global challenges we face, the climate crisis must not be overlooked. Here’s everything you need to know about Earth Day 2025.

### What is Earth Day?
Observed by millions, Earth Day is an annual event spotlighting critical environmental issues—from climate change to air pollution and deforestation. Organizations worldwide launch campaigns urging stronger protections for the planet, while many companies introduce new sustainability initiatives.

### When is Earth Day 2025?
Earth Day falls on April 22 each year, but the entire month (sometimes called Earth Month) and the week leading up to it (Earth Week) often highlight environmental concerns.

### Why April 22?
Earth Day was conceived by U.S. Senator Gaylord Nelson after a devastating 1969 oil spill in California. He proposed college teach-ins on environmental issues, choosing April 22 as a practical date between Spring Break and final exams.

The first Earth Day in 1970 drew 20 million Americans—about 10% of the population—to protests. Its impact was immediate: President Nixon established the Environmental Protection Agency and signed the Clean Air Act that same year.

In 1990, Earth Day went global, with activists expanding the movement to address worldwide ecological challenges.

### What’s the 2025 theme?
The 55th anniversary theme, Our Power, Our Planet, emphasizes collective action. Campaigners are urging a shift from fossil fuels to renewable energy, aligning with the COP28 goal to triple global renewable capacity by 2030.

### How can you participate?
Thousands of events—from marches to educational programs—are planned worldwide. Check local activities via interactive maps or explore Earth Day’s action toolkit, which covers plastic pollution, sustainable fashion, and climate education.

### Beyond Earth Day
At Vogue, we believe every day should be Earth Day. To stay engaged year-round, educate yourself on environmental issues through books, documentaries, and daily sustainable choices.

(Note: The original text contained minor inconsistencies, such as mentioning 2024 events in a 2025 context, which have been adjusted for clarity.)Here are some ways to live more sustainably: choose eco-friendly fashion, switch to renewable energy, reduce air travel, and cut back on meat, fish, and dairy. You can also get involved by joining local campaigns, contacting your political representatives, or donating to environmental organizations like Greenpeace, 350.org, and Rainforest Alliance.

When it comes to fashion, buy less but choose quality—support sustainable brands and shop second-hand. But be cautious of greenwashing, especially during Earth Month, as many companies treat it as a marketing opportunity. Watch out for vague claims and always check for proof behind environmental promises.
