We loveTokyo
As one of the world’s largest metropolitan areas, Tokyo is taking bold and significant steps toward a zero-emissions future. With high energy demand, dense development, and growing exposure to extreme heat and flooding, the city understands its responsibility as a global megacity and is acting accordingly.
The Zero Emission Tokyo Strategy sets out a clear path to decarbonisation across buildings, energy, transport, and waste, informed by the IPCC 1.5°C pathway. Solar panels are now required on new homes and buildings, energy efficiency standards are being strengthened, and zero-emission vehicle programmes are expanding across the city. Tokyo aims to halve greenhouse gas emissions from 2000 levels by 2030, cut them by more than 60% by 2035, and reach net zero by 2050, contributing to global efforts towards carbon neutrality.
Alongside mitigation, Tokyo is implementing adaptation measures. The Tokyo Climate Change Adaptation Plan addresses risks including heat, flooding, heavy rainfall, and public health, and includes the promotion of cooling shelters for residents during extreme heat events. In 2025, Tokyo issued the world’s first internationally certified resilience bond under the Climate Bonds Standard, mobilising investment in flood control, coastal protection, and related infrastructure.
Tokyo is also tackling the circular economy. Strategies are in place to reduce food waste, increase recycling of household appliances and electronics, cut plastic waste incineration by 40% by 2030 and 50% by 2035, and raise recycling rates for municipal solid waste to 37% by 2030 and 40% by 2035. Tokyo’s Green Purchasing Promotion Policy extends these commitments across the city’s supply chain.
Let’s go, Tokyo!

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.

Run by WWF
The initiative is run by WWF — the world’s leading nature conservation organization — passionate about building a future in which people live in harmony with nature.
To thrive and prosper
As a key aspect of that mission, we support the creation and development of cities that enable all people to thrive and prosper while respecting the ecological limits of our one and only planet!

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.
