Earth Day has come a long way since its inception in 1970. What began as a grassroots protest in the United States has evolved into a global movement, engaging more than a billion people every year across 190+ countries. In the UK, Earth Day is not just a symbolic occasion — it’s a pointed reminder of our shared responsibility to protect the natural world. From urban pollution to declining biodiversity, the environmental challenges we face today are urgent and wide-reaching. Earth Day helps focus attention and energy on those issues, turning concern into practical action that can be felt at every level of society.
The origins of Earth Day
The first Earth Day took place on 22 April 1970, thanks to the efforts of US Senator Gaylord Nelson and activist Denis Hayes. It came in the wake of environmental disasters like the 1969 Santa Barbara oil spill and a growing sense that unchecked industrialisation was causing real, often irreversible, damage to the planet. An estimated 20 million Americans joined protests, teach-ins, and community clean-ups. That initial momentum helped pave the way for major environmental reforms in the United States, including the US Clean Air Act and Clean Water Act, and the establishment of the Environmental Protection Agency (source).
While Earth Day began in the United States, it quickly gained traction globally. In the UK, the 1970s marked a turning point for environmental awareness. Groups like Friends of the Earth UK were founded in 1971, and by the end of the decade, environmental concerns — from acid rain to oil spills — were making headlines. Since then, the UK has seen a growing number of grassroots campaigns, government policies, and school curriculums focusing on environmental responsibility. Today, Earth Day offers an annual opportunity to step back, assess our impact, and rethink how we can live more lightly on the planet.
Why Earth Day matters
Earth Day brings environmental issues to the forefront in a way that’s tangible, inclusive, and uniting. It cuts through the noise of daily life and offers a clear space to focus — not just on the problems, but on what we can actually do. From overfishing to climate anxiety, the environmental crisis can feel overwhelming. Earth Day takes that weight and turns it into manageable, actionable ideas. It’s not about guilt — it’s about agency. It’s about doing what you can, where you are. And when millions of people do that at the same time, it starts to matter in a very real way.
15 meaningful ways to celebrate Earth Day in the UK
If you’re unsure how you can make a difference in your local community, there are plenty of ways to celebrate Earth Day and leave the planet (at least your part of it!) in a much better place than it was in when you got to it. Here are some things you can do that will leave a lasting impact.
Join a local clean-up.
The sight of rubbish along riverbanks, pavements, and woodland paths isn’t just unpleasant — it’s harmful to wildlife and ecosystems. Plastic waste, in particular, poses long-term threats to animals that may ingest or become entangled in it. Volunteering for a local clean-up event this Earth Day can make a genuine difference. Councils and environmental groups often list these events online, and you can find national campaigns run by organisations like Keep Britain Tidy. Want to make it social? Invite friends, neighbours or family to come along. It’s low-cost, high-impact, and helps build community.
Plant trees and native wildflowers.
Trees are nature’s powerhouses — they absorb CO2, filter air, and create habitats for thousands of species. Wildflowers, too, are vital for supporting bees, butterflies and birds. In the UK, native plants are particularly important as they’re adapted to the local climate and conditions. You don’t need a massive garden — a balcony, allotment, or even a verge can be transformed with the right seeds. The Woodland Trust offers free tree packs to schools and community groups, and the Royal Horticultural Society has excellent resources on planting for pollinators.
Audit your rubbish and reduce your waste.
Most people underestimate how much they throw away — and how much of it could be avoided. This Earth Day, take 10 minutes to dig through your own bins (yes, really). What are you tossing most often? Could you start using a compost bin? Switch to refillable containers? The Love Food Hate Waste initiative has excellent tools to help cut down on food waste, which remains one of the most impactful and preventable sources of household emissions. Reducing waste at the source is far more powerful than relying on recycling alone.
Support eco-conscious brands.
Where you spend your money matters. Every purchase is a small vote for the kind of economy we want. Take a moment this Earth Day to research the brands you use regularly. Are they transparent about sourcing? Do they use recycled packaging? Are they carbon neutral or aiming to be? Websites like Ethical Consumer can help you make more informed choices. You don’t have to overhaul everything overnight, but swapping just a few of your go-to brands for more sustainable ones can have ripple effects.
Share what you learn.
Environmental education doesn’t need to be formal or dry. Watch a documentary like Kiss the Ground, read The Future We Choose by Christiana Figueres, or listen to a podcast like Outrage + Optimism. Share what moved you — whether it’s a shocking fact or an inspiring story — with the people around you. Post it online, bring it up over dinner, or use it to start a new conversation at work. When more people understand what’s at stake, it becomes easier to move the needle.
Eat a low-impact meal.
Animal agriculture is a major contributor to greenhouse gas emissions, deforestation and water use. You don’t have to go vegan to make a difference — just one plant-based meal a week helps. This Earth Day, cook a meal that uses local, seasonal produce. Try meatless versions of comfort foods or explore recipes from cultures that naturally lean toward plant-based eating. The Carbon Trust has guidance on food-related emissions, and many apps now help track the carbon cost of your diet.
Ditch the car for the day.
If you can, commit to going entirely car-free on Earth Day. Walk, cycle, take the bus — or even work from home if that’s an option. Transport makes up a quarter of the UK’s emissions, and cutting down car usage (especially for short journeys) is one of the most straightforward ways to reduce your footprint. Groups like Sustrans offer route maps and advice for cyclists and pedestrians alike. You might even discover a new favourite route or walking shortcut.
Switch off and unplug.
‘Vampire energy’ — electricity drawn by appliances on standby — can account for up to 10% of a home’s electricity use. Earth Day is a great moment to get serious about switching off properly. Unplug chargers when they’re not in use, shut down computers fully, and turn off lights when you leave a room. It’s also a good time to reassess your energy provider. Companies like Octopus Energy and Ecotricity offer green tariffs that power your home with 100% renewable electricity.
Harvest rainwater and save water.
Clean water is a finite resource — and one we often take for granted. Installing a water butt can help reduce your reliance on treated tap water for gardening, especially during the drier summer months. Fixing leaks, choosing water-efficient appliances, and turning off the tap while brushing your teeth might sound small, but it adds up. The Energy Saving Trust estimates that even modest changes can significantly cut your water usage and energy bills.
Get involved in citizen science.
Citizen science projects rely on everyday people gathering data to support research. Whether it’s counting birds in your garden or logging wildflower sightings, your input matters. It helps build national databases that track species decline, seasonal shifts, and the spread of invasive plants. Initiatives like the RSPB’s Big Garden Birdwatch and Nature’s Calendar are simple to join and often family-friendly, too. Plus, once you start noticing what’s living around you, it’s hard to stop.
Switch to a renewable energy provider.
Most people don’t realise how easy it is to switch energy providers — or how big an impact it makes. Choosing a company that sources its electricity from wind, solar, or hydro reduces your home’s reliance on fossil fuels. Providers like Good Energy, Ecotricity, and Octopus Energy offer competitive tariffs and invest in the future of clean power. You can compare options using the Ofgem website.
Create a garden that supports wildlife.
Our obsession with tidy, trimmed, and weed-free gardens has left many outdoor spaces barren for wildlife. Even a small patch of long grass, a pile of leaves, or a shallow water bowl can support birds, hedgehogs, and pollinators. The RHS offers advice on how to make your garden a haven for animals, whether you have a sprawling lawn or a container garden on a balcony.
Cut down on single-use plastic.
Plastic pollution remains a global crisis. The UK government has taken steps — like banning plastic straws and cotton buds — but there’s a lot more we can do at home. Start small. Invest in a reusable coffee cup, swap cling film for beeswax wraps, or bring your own containers to takeaways. Websites like Zero Waste Club can help you find alternatives and rethink your everyday habits.
Write to your MP.
Policy change often starts with public pressure. Earth Day is a perfect excuse to send a message to your MP, asking for stronger action on climate change, biodiversity, or sustainable transport. Not sure what to say? Friends of the Earth offers templates and issue briefings. Politicians pay attention to the issues constituents care about — a short email really can make a difference.
Reflect, reset, and commit.
End your Earth Day by taking stock. What’s one thing you’ve learned? What habit could you change this month — not just today? It might be reducing food waste, cancelling a fast fashion habit, or committing to weekly walks in nature. Write it down. Tell a friend. Keep yourself accountable. Earth Day is a starting point, not an end goal. But like anything, it starts with a single step.
Earth Day isn’t just a celebration — it’s a checkpoint. It reminds us that the decisions we make at home, at work, and in our communities are tied to the health of the planet. Small acts become bigger when repeated and shared. Whether you’re planting a tree, writing to your MP, or just switching off the telly, Earth Day is where small changes can grow into real, lasting change. The real work starts on 23 April, and every day after that.
