• A friendly competition to mobilize cities to deliver on the Paris Agreement. 

• We aim to support and celebrate 100 cities with action plans for keeping the global average rise in temperature to below 1.5 °C. The world yearns for transformational leadership we want to encourage cities to develop needed skills and strategies to achieve this. 

• OPCC is the largest and longest-running competition of its kind. More than 400 cities on 5 continents have participated with at least one goal to reduce carbon emissions and increase climate resiliency. 

• 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.  The OPCC’s new, unique, and expert-verified methodology for verifying emissions reductions let participating cities report emissions, goals, and targets on standardized reporting platforms. 

• Participants’ data is then assessed and compared to the emission reduction trajectories recommended for their type of city in order to limit global warming to 1.5 °C or below. 

• This process guides cities to the most impactful actions they can take to cut emissions and align with 1.5°C target. 

• Ultimately, the goal is for cities to develop best practices and to be more strategic, efficient, and effective in their climate mitigation and adaptation plans. 

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

• The city decides to join! If you want your city to accept our challenge, ask your city officials! You have influence, and your voice is important!

• Let us know! If you don’t have a local WWF contact, send us an email at opcc@wwf.se and we will direct you to the right person.

• Cities report relevant data on global standardized city-data reporting platforms. WWF offers guidance.

• Based on the data entered, cities are prescreened and shortlisted.

• An international jury of urban sustainability experts selects national OPCC winners with the most ambitious and inspiring commitments and actions, based on reported data.

• All participating cities receive guidance from global experts on big-win impact reductions in line with 1.5 °C.

We are proud to announce that this year's One Planet City Challenge saw more entries than ever before.

In 2018, 50 cities across 5 continents—representing over 100 million citizens—participated in the We Love Cities campaign.
