2017-2018 OPCC participating countries
When registering to the cCR, cities in selected countries  also have the opportunity to participate in WWF’s One Planet City Challenge (OPCC) which uses the cCR as its reporting platform. This biennial challenge run by WWF, in collaboration with ICLEI – Local Governments for Sustainability, encourages cities to commit to and implement ambitious climate action plans – the most ambitious cities are later recognized as national and global winners.
Founded in 2011, the OPCC  celebrates cities that implement innovative and ambitious climate actions, acting with urgency to deliver on the 2015 Paris Agreement. Combined with a focus on climate actions and related sustainability initiatives, cities are also encouraged to focus on improving social equity and quality of life. WWF’s aim with the OPCC is to encourage the creation of One Planet Cities – places where citizens can thrive and prosper, while respecting global ecological limits. The OPCC recognizes and rewards inspirational cities from around the world. To date, the OPCC has engaged over 320 cities in more than 25 countries across 5 continents – and its outreach and engagement continues to expand. Is your city willing to take the lead in the transition toward a one-planet future? Then we hope it will join the 2017-2018 OPCC!
The OPCC has several phases:
The 2017-2018 OPCC also has a thematic focus on urban transport and mobility. Thus in addition to national or global winners, cities with ambitious mobility plans and actions will be recognized separately for this.
Finally, WWF and ICLEI recognize that while data reporting is crucial for understanding the progress cities are making on climate action, we are also aware that it can be a time-intensive task. To avoid reporting fatigue, OPCC requirements align with those of major global initiatives for city reporting, such as the Compact of Mayors. As a result of this alignment, your city can also join the OPCC with minimal additional reporting requirements. This is a unique opportunity to gain recognition for the ambitious work your city is doing, and inspire cities around the world!
Interested to join? The OPCC reporting period runs from 15 March- 29 September 2017. For more information, consult the OPCC Instructions (below) or access the official OPCC website. You can also contact the One Planet Cities Core Team, at: firstname.lastname@example.org.

 The OPCC was formally called the Earth Hour City Challenge (EHCC). Its name was changed in 2017, to reflect wider ambitions, beyond Earth Hour. Still, cities are encouraged to use Earth Hour to highlight and celebrate climate actions in cities and towns.
 Jury members are international urban sustainability experts, representing research institutes, UN agencies, multilateral development banks and international city networks. WWF is in contact with the jury, but recuses itself from the selection of winners.
