City Challenge 2014 - Congratulations Cape Town!

At a ceremony in Vancouver, Canada, WWF’s Earth Hour City Challenge (EHCC) awarded Cape Town, South Africa the title Global Earth Hour Capital 2014. The city is recognized for its ambition and pioneering actions to combat climate change in its effort to bolster quality of life for its citizens. Cape Town succeeds last year’s winner Vancouver, Canada.

Cape Town stood out as a role model for the Global South with a showcase of green programs and actions other cities can replicate. Cape Town demonstrates how city strategies to reduce carbon development and battle climate change can also help tackle other development priorities such as food, energy and water security. The city has taken bold steps towards transitioning its energy system away from fossil fuels and towards renewable energy with its roll out of a solar water heating program. Community engagement on sustainability issues and strong progress with energy efficiency, especially a large-scale retrofitting program for its buildings stock, were other pioneering actions highlighted.

Over 160 cities from 14 countries joined the competition, more than double the participation from last year. This year, the jury paid particular attention to each city’s level of ambition and innovation for low carbon development in relation to their local context.

The Vancouver ceremony also awarded the 13 other shortlisted cities for the global award as Earth Hour National Capitals. Along with Cape Town, selected as National Capital for South Africa.

Will your city inspire the world?

Over 300 cities from around the world have participated in Earth Hour City Challenge. These are cities that deserve recognition for their commitment to taking a leadership role in the transition toward a climate-friendly, one-planet future.

Earth Hour City Challenge in short

With more than 70% of the world’s CO2 emissions generated by residents in cities, the Earth Hour City Challenge has been created to mobilize action and support from cities in the global transition towards a climate friendly one-planet future. The challenge invites cities to report ambitious commitments and big win climate actions, in terms of GHG reductions as well as the co-benefits they provide  in relation to food, water and energy security challenges. Next launch of the challenge in 2017 will be the sixth round of WWFs international city challenge. 

How the challenge works

Cities are invited to report relevant data, plans and actions via an internationally recognized carbon reporting platform for cities, 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 reviewed by an international jury.
The international jury review development plans for building, transport, energy and food systems – solutions that will make a city greener and cleaner and improve living standards for residents. 

City Challenge Prize 2016

WWF commissioned Torstensson Arts & Design in Sweden to create an award in line with the sustainability theme of the Earth Hour City Challenge. Reflection conveys the idea that the work Paris, 2016 year´s Global Earth Hour capital, is doing should be reflected out in the world as a source of inspiration for other cities.
