We loveIlion
Ilion, located only a few kilometers northwest of Athens, is a city on the move, advancing practical action that aligns with national and European climate targets to improve everyday life and support a more climate-ready future. The city is focusing on steady steps that bring environmental progress and quality of life together.
Across Ilion, improvements in mobility, buildings, and public space are shaping this transition. A comprehensive EV Charging Plan, an operational e-bike sharing system and a series of road safety interventions enhance daily travel and connect neighbourhoods to key green areas, such as the Antonis Tritsis Environmental Awareness Park.
By leveraging funding tools, energy efficiency interventions are underway or planned, with schools and municipal buildings being upgraded alongside wider improvements to street lighting. At the same time, waste services are strengthening, with expanded recycling infrastructure and local systems that support daily participation.
Ilion is also taking steps to manage water more effectively and improve resilience, including flood-protection works and better water use in public green spaces. These actions highlight how climate action is central to the city’s growth and future well-being.
Let’s go, Ilion, building a brighter future!

Why we love cities
Over 50% of people live in cities – generating over 70% of our climate footprint
But cities also offer an immense opportunity to create better places to live while contributing to a healthier
planet. Through better transport, green buildings, harnessing the power of nature, wasting less and loving
more, cities can lead the way to a climate-friendly future.
We love to get around
We love to get around
Our participating cities are transforming the way people travel. For sustainable cities, improving the way people get around also means reducing the amount of energy we use while improving air quality and health. Transportation accounts for 25% of global energy use so cities are finding ways to change that. Car-free and car-restricted areas, electrification, more public transport, promoting cycling and pedestrian-friendly streets are just some of the better ways to travel that will lead to a healthier environment.

We love the power of nature
We love the power of nature
Our participating cities love the power of nature and are becoming hotspots for nature-based solutions and renewable energy solutions. Right now, city dwellers are responsible for over 70% of our planet’s energy-related carbon emissions. But by becoming trailblazers for renewables, cities have the opportunity to change that. From solar water heating, geothermal heating, biogas, wind farms, solar electricity and smart grids, renewables don’t affect the air we breathe, our water supplies and our climate system. And that means healthy, happier people.

We love green buildings
We love green buildings
Our participating cities are at the forefront of improving the places that we live and work. Buildings define the character of our cities. But it’s not just about what they look like, it’s about how they work too. Buildings use one third of the world’s energy, and in bigger cities they account for up to 80% of carbon emissions. By championing new designs, incentives and standards, cities are leading the way to more energy-efficient homes, and inspiring a global trend where new buildings become energy producers rather than energy consumers.

We love clean living
We love clean living
By wasting less and loving more, our participating cities are leading the way to smart waste solutions. Like turning waste into a resource. Biogas, district heating, compost, fertilizer, irrigation, and recycled goods all come from waste and waste water. And making these resources creates jobs too. By minimizing and trapping waste for material and energy, smarter urban waste management improves the economy, the environment and promotes clean living – all at the same time.

We love to eat
From top restaurants to cool street stalls,
food is a big part of what defines a city
From top restaurants to cool street stalls, food is a big part of what defines a city. It’s also becoming a big part of the sustainability journey. Climate-smart food procurement and the promotion of more veggie based diets addresses food’s climate impact as well as health issues; urban farming is improving food security; while hospitals and schools are recycling packaging and composting leftovers so nothing goes to waste. The more cities use the power of food, the better cities will become.

Common questions
- What is the We Love Cities campaign?
We Love Cities is a public engagement campaign that allows people across the world to express support for sustainable urban development by voting for their favorite finalist from WWFs One Planet City Challenge and posting improvement suggestions for these cities. The One Planet City Challenge is the world’s largest and longest running city challenge. You can read more about it here. With the We Love Cities campaign we aim to:
Inspire and raise awareness for the sustainability progress being made in cities.
Give the general public an opportunity to celebrate, vote and upgrade their city through making suggestions to decision makers.
Reward communities and strengthen the bond between the public and decision makers.
- Does the number of votes a city receives in the We Love Cities campaign have an influence on the selection of the national and global winners of the One Planet City Challenge?
No. The We Love Cities campaign has no influence on the outcome of the One Planet City Challenge (OPCC). The OPCC winners are selected through a jury process based on the data reported by the cities on the internationally recognized unified reporting platform hosted by ICLEI and CDP.
- Why are there no cities from my country involved?
The cities profiled here are all finalists in WWF’s biennial One Planet City Challenge.
If you would like to suggest your city for the One Planet City Challenge, you can do so on this form here.
If your country is included in the One Planet City Challenge but your city is not profiled here, either your city chose not to participate in the Challenge or it participated but didn’t make it past the pre-selection process. In either case please encourage your mayor or public officials to inspire the world by developing and reporting really ambitious climate action plans next year.
