As one of the most iconic and vibrant cities in Europe, Barcelona is also becoming more conscious of its environmental footprint. Whether you live in the city or are just visiting, adopting a greener lifestyle in 2025 is not only essential but can also be a rewarding and empowering experience. In a city that’s a hub for art, culture, and innovation, it’s only fitting that Barcelona continues to evolve into a more sustainable metropolis. Here are ten small but impactful changes you can make to live a greener lifestyle in Barcelona this year.

1. Reduce Single-Use Plastics

Barcelona, like many major cities, is making strides toward reducing plastic pollution. Yet, the problem remains, especially in tourist-heavy areas like La Rambla or Barceloneta Beach. You can do your part by reducing your use of single-use plastics. Carry reusable shopping bags, opt for a metal or bamboo straw, and take your coffee cup when getting your morning latte. The more you cut down on plastic, the less waste ends up polluting Barcelona’s beautiful streets and beaches.

2. Embrace the Mediterranean Diet and Eat Locally

Barcelona is a foodie paradise, and one of the best ways to live more sustainably is by embracing the Mediterranean diet. Focus on fresh, local produce, which has a lower carbon footprint compared to imported food. Visit Barcelona’s markets, like Mercat de Sant Josep de la Boqueria or Mercat de Sant Antoni, where you can buy seasonal vegetables, fresh seafood, and local cheeses. By eating more plant-based meals and choosing locally sourced ingredients, you’ll be supporting local farmers while also helping to reduce your environmental impact.

3. Switch to Energy-Efficient Appliances

Barcelona’s sunny days make it the perfect city to adopt solar energy. In 2025, consider installing energy-efficient appliances in your home, such as LED light bulbs, energy-efficient air conditioning units, or solar panels. The Spanish government provides incentives for renewable energy initiatives, and solar panels can help reduce your electricity bills. For renters or those who don’t own a home, simply switching to more energy-efficient options when replacing old appliances can make a big difference in reducing your overall consumption.

4. Use Barcelona’s Public Transport

Barcelona is famous for its excellent public transport system, including metro, buses, and trams. Using public transport not only helps you avoid traffic but also significantly reduces your carbon emissions compared to driving a car. Additionally, the city has embraced cycling as a sustainable mode of transport. You can rent a Bicing bike to explore the city’s iconic landmarks or use one of the many bike lanes to get around in an eco-friendly way. Cycling and using public transport are both practical and efficient ways to enjoy Barcelona without leaving a huge carbon footprint.

5. Reduce Water Consumption

Barcelona has experienced periods of water scarcity in recent years, making water conservation a priority. You can help by making small adjustments in your daily habits. Shorten your showers, fix leaks, and consider installing water-saving devices like low-flow showerheads or water-efficient toilets. If you live in a house with a garden, think about collecting rainwater for irrigation. By being more mindful of your water use, you’ll contribute to maintaining the sustainability of this Mediterranean city, where water is a precious resource.

6. Choose Sustainable Fashion

Barcelona is home to a growing number of fashion brands that prioritise sustainability. In 2025, instead of shopping at fast-fashion stores, consider investing in locally made, eco-conscious clothing. Barcelona’s El Born district is known for its independent boutiques, where many designers use organic, fair-trade materials and focus on slow fashion. Consider shopping second-hand at vintage stores or even swapping clothes with friends to extend the life of your garments. By supporting local, sustainable fashion, you’ll reduce textile waste and promote ethical production practices in the city.

7. Get Involved in Urban Gardening and Grow Your Food

Urban gardening is gaining popularity in Barcelona, with many citizens transforming balconies, rooftops, and small plots of land into green spaces. Whether you have a large terrace or just a small balcony, growing your herbs and vegetables is a wonderful way to reduce your environmental impact. Barcelona’s climate is ideal for growing crops like tomatoes, peppers, and herbs like basil and rosemary. Local initiatives like Huertos Urbanos provide spaces for community gardening, which is a great way to learn more about sustainable farming practices while contributing to local food production.

8. Compost Your Food Waste

Food waste is a significant contributor to landfill issues and greenhouse gas emissions. In Barcelona, several initiatives promote composting, especially in urban areas. Composting your food scraps not only reduces waste but also produces nutrient-rich soil for gardens or community green spaces. Many neighbourhoods in Barcelona offer composting bins for residents, and you can even start your composting system at home. It’s an easy change that has a big payoff for both the environment and your local community.

9. Choose Eco-Friendly Cleaning Products

Traditional cleaning products can contain toxic chemicals that are harmful to your health and the environment. In 2025, opt for eco-friendly cleaning products made from natural ingredients like vinegar, baking soda, and essential oils. You can also create your cleaning solutions at home, which are not only safe for the environment but also much cheaper than commercial products. Many stores in Barcelona now offer refill stations for cleaning supplies, so you can reduce packaging waste while keeping your home clean and green.

10. Support Local and Sustainable Businesses

Barcelona is filled with local businesses that prioritise sustainability, from zero-waste stores to eco-friendly cafes and sustainable fashion boutiques. By supporting these businesses, you’re helping to promote a greener economy and a more sustainable way of life. Whether it’s enjoying a meal at a farm-to-table restaurant like La Colmena, shopping at a zero-waste shop in Gràcia, or purchasing artisanal goods made from recycled materials, your spending choices can have a direct impact on the city’s sustainability efforts. Seek out businesses that align with your environmental values and help make Barcelona a greener place for everyone.

Adopting a greener lifestyle in Barcelona doesn’t require dramatic changes, but rather small, thoughtful adjustments that can have a significant impact. From reducing plastic waste to supporting local businesses, every action counts in preserving the beauty and sustainability of this incredible city. As Barcelona moves toward a more eco-conscious future, the small changes you make in 2025 can help ensure that the city remains a vibrant, sustainable, and inspiring place for generations to come. Start with one or two of these changes, and watch how your lifestyle shifts toward a greener, more sustainable way of living.
