The world’s leading reporting platform for local and subnational climate action – the carbonn Climate Registy (cCR) – welcomes its 500th reporting city today, with the new addition of the City of Bristol, United Kingdom.

ICLEI, the leading cities network operating carbonn Climate Registry, announced this today at the ongoing United Nations Lima Climate Change, taking place 1–12 December 2014 in Lima, Peru.

Bristol, the European Green Capital 2015 and the first UK city to report into the cCR, now joins the growing list of pioneering cities that have embraced leadership and responsibility in tackling climate change locally and inspiring action globally. Other frontrunners on the cCR include: Seoul, South Korea; Rajkot, India; Belo Horizonte, Brazil; Hermosillo, Mexico; Cape Town, South Africa; and Paris, France.

Bristol’s Mayor, George Ferguson, commented, “Bristol aims to cut emissions by 40% by 2020. We’ve already cut emissions by 20% since the base date of 2005. Reporting our climate action data into the carbonn Climate Registry helps us to keep track of our targets and inspire cities and nations to set more ambitious targets and act urgently to address the pressing issue of climate change.”

“We want them to come on board and help us tackle this together. Over 50,000 Bristolians are already involved with green initiatives as we prepare for our year as Britain’s first European Green Capital in 2015. We are proud of our reputation as a national and international leader when it comes to sustainable actions and we hope to influence the wider international community to do much more.”

The cCR’s latest count reveals data from 500 cities and provinces / states representing more than 12% of the world’s urban population, covering community greenhouse gas (GHG) emissions of more than 2.8 gigatonnes of carbon dioxide equivalent per year (GtCO2e/pa).

Breaking down the reported data, these advanced cities have reported a total of over 1,000 climate and energy commitments (showing their targets / goals), 1,000 GHG inventories (showing they are monitoring progress) and over 5000 mitigation and adaptation actions (showing they are acting).

ICLEI Secretary General Gino Van Begin noted, “The cCR data presents the growing evidence base that local and subnational governments are effectively addressing climate change. With the announcement of Bristol as the 500th reporting participant of the cCR, we hope to further inject positive momentum into the climate negotiations and help bring about meaningful Lima outcomes which will then lay the groundwork for the new climate accord to be adopted in Paris next year.”

“We congratulate Bristol for stepping up their climate ambition and for demonstrating the potential impacts of local climate action by reporting into the carbonn Climate Registry. The carbonn Climate Registry was recently designated as the central repository of the Compact of Mayors. Launched at the Climate Summit 2014 in New York, the Compact of Mayors is the biggest initiative for Mayors and city officials to make drastic cuts on their GHG emissions, report progress and prepare for the impacts of climate change.”
