WWF's One Planet City Challenge for 1.5°C

Over half of the world’s inhabitants live in cities, and urbanization marches on. Cities account for 70% of carbon emissions and generate more than 80% of global GDP. In cities, problems tend to multiply, but they are also important testbeds, and multipliers, of solutions. As centers of both political and corporate power, cities can lead the climate transition.

These are some reasons why WWF created the One Planet City Challenge (OPCC). Through it we help local governments slash their carbon emissions.

WWF’s One Planet City Challenge (OPCC) in short:  

  • It’s a friendly competition to mobilize cities to deliver on the Paris Agreement.

  • We aim to support and celebrate 100 cities with action plans for 1.5 °C by 2020. The world is yearning for transformational leadership to discover how the transition can be done.

  • OPCC is the largest and longest running competition of its kind. More than 400 cities on 5 continents have participated at least once.

  • Participants have already raised ambitions in global reporting initiatives by reporting more than 5,700 actions with a total of 3.9Gt GHG emissions reduction potential by 2050. 

  • With the OPCC’s new unique and expert-verified methodology, we have integrated IPCC data from the Special Report on Global Warming of 1.5 °C.

  • Participating cities will report emissions, goals and targets on standardized reporting platforms.

  • The participants’ data will then be assessed and compared to the emission reduction trajectories recommended for their type, in order to limit global warming to 1.5 °C.

  • We then guide cities to the most impactful actions they can take to cut their emissions and align with 1.5°C

  • Winning cities should develop best practice and be strategic in their climate mitigation and adaptation plans.

  • The updated OPCC runs in collaboration with city networks such as the Global Covenant of Mayors, ICLEI, C40 and CDP.
