carbonn Climate Registry

Towards measuring, reporting and verification of 100% Renewable Energy

Over 700 local and subnational governments, representing 9% of the global population, currently report their climate and energy data to the carbonn® Climate Registry (cCR), the voluntary global reporting platform available to all local and regional governments. It was created to enhance transparency, credibility and recognition of local climate action. Use this opportune moment in changing global politics to draw worldwide visibility on targets, actions and performance of your city or region. Showcase your leadership.

Why report at this time? There are several reasons to profile local leadership at this time. We are not on track to stay well below the 2°Celsius target of the Paris agreement; local climate action may indeed help to raise the level of ambition of climate change mitigation; and sharing the local win-win approaches and many associated benefits can help mobilize many other cities, towns and regions to also engage.

Why report to the carbonn Climate Registry? The cCR is a free service provided by ICLEI – Local Governments for Sustainability (ICLEI) to all local and sub-national governments. By reporting here, you will join the ranks of leading cities, towns and regions demonstrating how they accelerate climate action. The good practice of public reporting also shows good governance in being transparent and accountable. ICLEI supports reporting with quality checks to ensure information is credible and then publicly displayed. Reporting to the cCR not only enhances opportunities for visibility, but offers benchmarking and peer comparison, guidance to access financial support and technical assistance to tackle climate change mitigation and adaptation.

You can help shape global climate advocacy messaging. Data in the cCR serves as an important advocacy element for ICLEI, also in its role as focal point for the Local Governments and Local Authorities Constituency at the UNFCCC (United Nations Framework Convention on Climate Change). ICLEI lobbies for improved access to resources and for national enabling frameworks that can help scale up local climate action. Reported data is processed and aggregated, with annual reports used during the climate negotiations. The cCR Digest 2015-2016 produced for the 22nd Conference of Parties (COP22) taking place in Marrakesh, Morocco in November 2016 is available here.  

100% Renewable Energy - We warmly invite you to report to the cCR what you do in the field of renewables: targets, tracking performance and actions. The carbonn® Climate Registry (cCR) is the central reporting platform for cities, towns and regions engaged in the Global 100% RE Campaign. If you have an interest in 100% RE, please also consider participating in the Global 100% Renewable Energy Cities and Regions Network, linked to the Global 100% RE Campaign. This community of practice brings together cities, towns and regions that are driving the transition towards 100% Renewable Energy. It facilitates peer-learning and accelerates progress, helping to develop approached and standards to shape this transition. Examples of local and subnational governments engaged include Vancouver (Canada), Malmö (Sweden), Jeju Province (Republic of Korea) and Canberra (Australia).

The City of Aspen, USA, a renowned ski tourist destination, is experiencing on average 21 fewer days of snow coverage than 50 years ago, with visible negative impacts on the local and regional economy. The city has long adopted environmental and climate stewardship as its motto. In August of 2015 the City of Aspen achieved 100% renewable electricity, a target established over a decade ago.

Investments in renewable energy over the last decade have enabled the City of Aspen’s municipally owned electric utility to replace fossil fuels. From August of 2015 the utility provides 100% renewable energy power, with the signing of a contract for additional wind power with the Municipal Energy Agency of Nebraska, a wholesale electric energy provider. Aspen’s electricity mix is now 53% wind power, 46% hydropower, and 1% landfill gas. This achievement is being celebrated! It significantly reduced Aspen's carbon footprint and allowed the City of Aspen to catalyze RE development in the western United States (NREL, 2016).

“We’ve prepared for the new energy economy by powering Aspen’s electric utility with 100% renewables. We’re finding our rates are among the lowest in Colorado, and that a commitment to a sustainable future is practical, profitable, and improves local quality of life.” — Steve Skadron, Mayor, City of Aspen, USA.

The City of Växjö, Sweden has already in the 1990s made a long-term commitment to climate protection and sustainability. The City reporting to the cCR shared a community-wide target of 100% renewable energy by 2030, and reports in great detail on its performance. In 2015, the RE share in district heating was already above 96% due to the use of local biomass and geothermal energy. Learn more about this and the Global 100% Renewable Energy Cities and Regions Network - the latest brochure is available.

It is important to continue to celebrate achievements in the transition to a 100% RE future. We look forward to learn more about your commitments, actions and performance!
