  • What is EHCC?
The Earth Hour City Challenge is a WWF’s initiative to mobilise action and support from cities worldwide towards a climate-friendly, one-planet future, and to stimulate the development and dissemination of best practices for climate mitigation and adaptation. 
  • How did EHCC start?  

30 Swedish cities were first challenged in 2011 to present inspiring and credible plans to reduce their carbon footprints to zero within the next few decades, and to positively impact the world with their solutions.

  • How to win EHCC?
Cities who join the challenge are required to submit to the jury their Carbon Data Inventory together with at least, one commitment and one sustainable development action plan for building, transport, energy and food systems.  A short-list of National Earth Hour Capitals representing their own countries (a city per country) is created for the final round. The worldwide winner is entitled the “Global Earth Hour Capital”.
  • Who won EHCC in previous years?
Global Earth Hour capitals are respectively Vancouver (2013), Cape Town (2014) and Seoul (2015). The  later beats out 165 contestants from 17 nations with an ambitious initiative to reduce greenhouse gas emissions by 10 million tons and to achieve 20 per cent electricity self-reliance by 2020.
  •  Who is participating EHCC 2016?
The City Challenge 2016 is participated by over 125 citties from 21 countries around the world.

Under the frame of the City Challenge, WWF creates a digital platform - We Love Cities - that allows people across the world to express support for sustainable urban development by voting on the selected Green cities and posting improvement suggestions for these cities. In 2015, Balikpapan (Indonesia) becomes the Most Lovely Sustainable City.
The campaign aims at:
  • Inspiring and raising awareness for the sustainability progress being made in cities,
  • Giving the general public an opportunity to celebrate, vote and upgrade their city through making suggestions to decision makers,
  • Rewarding communities and strengthening the bond between the public and decision makers.
