One Planet City Challenge

What we are doing

TThe WWF One Planet City Challenge (OPCC) is a friendly, international challenge that celebrates national and global frontrunners responding to the climate change crisis. This long-standing challenge reviews cities’ climate actions and ambitions, and assesses whether they align with the goals set forth in the Paris Agreement. The more ambitious, credible, strategic and innovative a city’s approaches are, the greater its chances are of being selected as a national or global OPCC winner. Participating cities are thus evaluated on their contribution towards achieving the goals set forth in the Paris Agreement. The OPCC process creates leadership and system transformation by helping cities acquire needed skills and strategies to achieve their ambitious goals, by enabling city authorities to understand their emissions and how to face emission reductions (and ultimately how to halve emissions by 2030), and how to define adaptation plans to protect their citizens and local context. WWFs biennial OPCC runs in in tandem with cities’ reporting on the CDP ICLEI Unified Reporting System (URS), allowing for all of a city’s environmental data to be collected in one place. In addition, activating their CDP ICLEI URS profile allows cities to participate in workshops and webinars to help improve on climate action efforts, as well as the potential for being globally recognised for climate leadership and action implemented at city level. OPCC aims to highlight diverse challenges and solutions for cities in different parts of the world, while identifying options for networking and collaboration between cities and other stakeholders. However, the OPCC raises the global profile of all participating cities, and builds awareness and support for success at COP26 and future climate events.

How we are tracking

- targeted OPCC sign-ups of existing and new cities in both South Africa (total amongst partners = 12) and Sub-Saharan Africa (SSA) (total amongst partners = 18) through the CDP ICLEI Track); - offer technical support to less capacitated cities to report on the CDP-ICLEI Track platform; - Light-touch technical assistance Webinar (1) on climate financing options for implementation of climate change actions reported on via the OPCC (offered in English and French) - Analysis of data and development of case studies that depict the commitments, challenges, implementation progress and ambitions of African cities linked to the OPCC campaign

What we are achieving

WWF-SA and ICLEI Africa have partnered on the One Planet City Challenge (OPCC) to assist African districts, metros and municipalities to submit their climate action plans or projects via the CDP ICLEI Unified Reporting System (URS), motivating the need, and highlighting opportunities, for both adaptation and mitigation initiatives at the local level. In addition, ICLEI Africa provides technical assistance and training on CDP ICLEI Track reporting to new OPCC participants, and further assist existing participants as needed on new actions being reported. Disclosing environmental data through CDP provides cities with improved engagement on climate activities, and centralizes data and tracks progress. CDP provides cities with all publicly available data, evaluates cities' responses, benchmarks performance against peers, and also finds areas of opportunity or improvement for cities. Through previous iterations of OPCC, participating cities have reported a total emissions reduction potential of 3.9Gt GHG (by 2050) using CDP-ICLEI’s globally recognized reporting system.
