We Love Cities 2016
We Love Cities invites people across the globe to show their support for the impressive efforts 46 impressive cities are making towards sustainability. Between April 26 - June 19, we welcome you to vote for your favorites, share what you love about them via photos and videos and to submit suggestions for how cities can become more sustainable. #WeLoveCities

The Earth Hour City Challenge initiative has been created to celebrate cities that are taking amazing steps forward in creating a greener, cleaner and more sustainable city to live in, while inspiring other cities to do the same.

Christiana Figueres, member of the international jury for the WWF Earth Hour City Challenge, recognized the participation of all cities involved in the challenge at the Award ceremony 2013. City-level response is integral in the fight against climate change and cities that engaged in the Earth Hour City Challenge are leading the way in policy implementation.

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. Running now is the fifth 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. For participants in Earth Hour City Challenge 2016:
