At the World Mayors Summit on Climate in Mexico City on 21 November 2010, two groundbreaking initiatives were launched: Global Cities Covenant on Climate - "the Mexico City Pact", and the carbonn® Cities Climate Registry (cCCR) as the global mechanism for reporting local climate information.
WWF’s Earth Hour City Challenge (EHCC) has recognised the City of Vancouver, Canada, for its innovative actions on climate change and dedication to create a sustainable, pleasant urban environment for current and future residents.
After carefully reviewing the merits of the six finalists, the EHCC jury of experts unanimously cast their votes for Vancouver as the first ever Global Earth Hour Capital. Also in the running for the title were finalists Forlì in Italy; New Delhi, India; Oslo, Norway; Uppsala, Sweden; and San Francisco, USA.
As of March 2013, 302 cities from 42 countries, controlling a community GHG emissions of around 1.5 GtCO2e annually, reported 561 energy and climate commitments, 578 GHG inventories and 2471 mitigation/adaptation actions/action plans at the cCCR. This remarkable accomplishment has been achieved through 3 main drivers:
1. Voluntary reporting pursuant to a global political commitment (the role of the Mexico City Pact)
2. Capacity building at the national level (the good practice of Local Government Climate Registry Japan)
3. Creating incentives (partnership with WWF Earth Hour City Challenge)
The cCCR clearly highlights the importance of local governments in raising the global level of ambition to reduce GHG emissions, increase climate risk adaptation preparedness and move towards low-emissions development. This immense potential can be rapidly mobilized if the global climate community engages with local governments and scales up direct technical and financial support.
