The annual event, rewarding cities for inspiring actions on climate change, takes on special significance this year as a new global climate treaty is readied for agreement.
Last year's global winner was Cape Town, recognised for demonstrating how low-carbon development and climate change mitigation can be accomplished while simultaneously addressing other development priorities.
This is the third year that WWF is recognising cities for helping build a sustainable and safe energy future. An expert jury will now review the actions and commitments reported by these cities and identify one sustainability leader per country for the National Earth Hour Capital Awards to be presented on 9 April in Seoul, South Korea.
"Cities are leading the way toward a fair, climate-resilient future. While national governments have largely talked about solutions, real changes are being created every day from the solar street lamps to the clean transit systems of the world's cities," said Carina Borgström-Hansson, lead for WWF's Earth Hour City Challenge.
The Earth Hour City Challenge works to mobilise action and support from cities in the global transition toward a sustainable future powered by renewable energy. WWF is convinced that these cities can act as a source of inspiration for countries as they refine their positions for the climate negotiations set to take place in Paris in December.
WWF is encouraging people all over the world to show their support for the impressive efforts that cities are making toward sustainability, and to participate in the We Love Cities campaign. For the next eight weeks, web visitors are invited to vote for their favourites among the finalist cities, and to share what they love about these cities via photos and videos. The public is also welcome to submit suggestions for how the cities can become even more sustainable.
"Cities are innovation hotspots that are creating solutions to put the world on track for a climate-safe future. To help them succeed, we urgently need supporting action from policy-makers, businesses and financial institutions that are prepared to slam the door on fossil fuels and open it fully for a renewable future," said Borgström-Hansson.
WWF works closely with International Council for Local Environmental Initiatives (ICLEI) - Local Governments for Sustainability in mobilising cities to join the challenge and enabling their reporting through carbonn Climate Registry (cCR).
"Cities are constantly finding new ways to tackle climate change and scale up their climate actions. Many of these actions are already showcased on ICLEI's carbonn Climate Registry," says Gino Van Begin, Secretary General of ICLEI. "Through our partnership with WWF's Earth Hour City Challenge, more cities have been inspired to set ambitious climate targets, report against these targets, and provide an excellent example of what is possible not only for other cities, but also for the global climate community."
