Will your city be the next Earth Hour Capital?

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 submit inspiring and credible urban development plans that dramatically increase the city’s use of renewable energy.
This year 163 cities in the following seventeen countries are participating in the Earth Hour City Challenge; Brazil, Canada, Colombia, Finland, France, India, Indonesia, Malaysia, Mexico, Republic of Korea, South Africa, Singapore, Spain, Sweden, Tanzania, Thailand and USA.

WWF, with the support of Accenture, have selected 44 finalists who are now being reviewed by an international jury.  The jury will analyze actions and commitments reported by these cities, and will identify one sustainability leader per country for the National Earth hour Capital Awards. From among these cities one global Earth Hour Captial will also be selected. These leading cities will be presented during the ICLEI World Congress on April 9 in Seoul, South Korea.

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.

How the challenge works

Cities were 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 were provided in collaboration with ICLEI and the final plans and data reviewed by an international jury. Reporting on the platform closed in September.

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. This year cities from 17 countries participate in the Earth Hour City Challenge.

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.
