Let Your City Inspire the World

In cities, everything is closely connected. As cities and urban populations expand across the globe, the problems in cities also tend to multiply. The good news is that solutions can also multiply. And fortunately, solutions already exist today that have the potential to meet the demands of urban lifestyles, without exhausting the planet’s ecological capacity.

So WWF created the One Planet City Challenge (OPCC) to highlight these solutions, and to recognize and reward cities that are busy putting them to use. These are cities that aim to provide sustainable housing, transportation, and energy for their residents while simultaneously engaging their citizens and acting as inspirational role models for other cities around the globe.

The One Planet City Challenge invities cities in participating countries to report ambitious and innovative climate actions, and to demonstrate how they are delivering on the 2015 Paris Agreement on climate change. Data is entered on the carbonn® Climate Registry, and outreach and support is provided to cities in collaboration with ICLEI – Local Governments for Sustainability. Final plans and data are then reviewed by an international jury of experts tasked with identifying the most outstanding cities. After a process involving a thorough scrutiny of submissions and jury deliberations, national and global winners are selected and awarded at a global prize ceremony. 

Since the inception of the Challenge in 2011, WWF has engaged over 400 cities across 5 continents. In the 2017-2018 round, 132 cities in 23 countries participated in the One Planet City Challenge, which has a thematic focus on sustainable transport and mobility as a major challenge facing cities everywhere.

Right now, finalist cities are invited to participate in the related We Love Cities campaign to engage their citizens in expressing support for their cities, as well as sharing ideas for improvement. Simultaneously, an international expert jury has reviewed all finalist cities, selecting both national and a global winner, which will be announced in a press release in the second half of 2018. Please contact us at

Cities are invited to report relevant data, plans and actions via the world's leading carbon reporting platform for local governments and regions, carbonn® Climate Registry, cCR, managed by ICLEI – Local Governments for Sustainability. Outreach and support to cities is provided in collaboration with ICLEI and the final plans and data are reviewed by an international jury.

Cities wishing to participate in the One Planet Ctiy Challenge need to create an account in the cCR; there they can also register for the 2017-2018 OPCC. The city will be recognized as a “cCR Registered City” as long as data is reported in the Profile section. By registering for the OPCC, the city will also be counted as an OPCC participating city. Once the city has met the minimum reporting criteria, it will be recognized as an OPCC candidate city. More information can be found at:

Registration and Data Reporting as an OPCC candidate includes the following steps:
1. The city registers on cCR and agrees to the cCR Terms and Conditions.
2. The city indicates interest in joining the OPCC from its cCR account and agrees to the cCR Terms and Conditions for OPCC Candidates
3. The city downloads the reporting sheets that will be pre-populated with previously reported data, if the city has formerly participated in the OPCC.
4. The city submits its completed cCR reporting sheets, with all required information, to the Bonn Center for Local Climate Action and Reporting (email to before 29 September 2017 – the closing date for OPCC candidate cities. Before the final deadline, cities can also benefit from up to 2 rounds of feedback to improve their chances, by reporting before 15 June 2017. Cities reporting before 12 August 2017 can access one round of feedback.  

An international jury of urban sustainability experts will look for cities that demonstrate inspiring, ambitious and credible climate agendas that reflect how cities contribute to meeting the Paris Agreement goals. Joining the coalition of cities committed to the Compact of Mayors, and the Global Covenant of Mayors for Climate and Energy – as well as following up these commitments with action – will be considered a positive attribute in the evaluation procedure. Higher ambitions and the impact of corresponding action plans will be particularly favored. The thematic focus for this year’s One Planet City Challenge is sustainable transport, and the jury will be paying special attention to cities that present ambitious mobility plans and actions.

The jury will consider differences in resources and starting points in order to ensure a level playing field for evaluation. Overall, the jury will be looking for cities that:

- Demonstrate determination to align with a transparent and science-based GHG emission reduction trajectory
- Have ambitious and strategic action plans to meet stated commitments
- Integrate actions into coherent and overarching climate action plans
- Lead, with respect to local context and conditions
- Highlight sustainable mobility efforts

The One Planet City Challenge jury is comprised of leading experts within the field of urban sustainablity from around the globe. With extensive local and regional knowledge jury members are uniquely qualified to evaluate the contribution of participating cities in achieving the goals set forth in the 2015 Paris Agreement.

The Makings of a Winner

This year marks the fifth anniversary of WWF’s international challenge to cities. The Challenge has engaged 320 cities across five continents to date. Of these four global winners have been identified and rewarded for their commitment to creating cleaner, greener and more sustainable places for us to live, work and thrive in. WWF is now on the look out for the next city to join these ranks. Will your city be the next global winner of the One Planet City Challenge?

Vancouver, Canada

Vancouver, the first global winner in 2013, was recognized for its leadership and commitment to sustainable urban development in spite of low national ambitions in Canada at the time. Vancouver was proclaimed to be a role model for holistic and strategic urban planning. The city aims to engage all sectors of society, and puts particular effort into public engagement.

Cape Town, South Africa

The global winner in 2014 was Cape Town. The city impressed the international jury of experts by demonstrating how low carbon development and climate change mitigation can be accomplished even in a city with many important development priorities. The city showed great progress in energy efficiency, and was very successful in engaging citizens in its climate work. 

Seoul, South Korea

Seoul is also a city worthy of recognition, and was crowned the global winner in 2015. The city was rewarded for its ambitious program to reduce greenhouse gas emissions by 10 million tons by 2020. And for dedicating a solid budget to the expanding the use of solar power among citizens, and reducing transport emissions through greener fuels, increasing the numbers of bus lanes and the creation of car sharing programs.

Paris, France

The most recent global winner is the city of Paris - a unanimous favorite among jury members in 2016. Paris showed innovative and robust climate leadership worthy of recognition and replication. The city’s comprehensive long term vision supported by a revision process that occurs with regular intervals was found to be of particular interest.


Congratulations Bogor!
Winner of We Love Cities

Bogor, Indonesia, won We Love Cities 2016 with a landslide victory. Bogor showed an amazing ability to reach out to its citizens and to rally their support. #WeLoveBogor 

WWF's We Love Cities campaign invited people across the globe to show their support for the impressive efforts cities are making towards sustainability. Over 300 000 voted for their favorites, shared what they loved about them via photos and videos and submitted suggestions on how cities can become more sustainable. #WeLoveCities
