The Climate Summit of Local and Regional Leaders, organized by ICLEI and co-hosted by the City of Bonn and the State of North Rhine-Westphalia, shows the impact and ambition of subnational climate action and serves as a call to action to raise ambition at all levels. It is the flagship event in the middle of a full two-week program for local and regional leaders at COP.

In its role as focal point for the Local Governments and Municipal Authorities (LGMA) Constituency, one of nine key stakeholder groups recognized by the UNFCCC, ICLEI will help deliver key messages from the Summit as input into the climate negotiations.


Now is the time to implement the Paris Agreement and keep the global temperature rise well below 2 degrees Celsius. To achieve this, all levels of government need to work together to track performance and implement effective, coordinated climate action.

1,019 local and regional governments from 86 countries, representing 804 million people, have reported their emissions reduction targets on the carbonn Climate Registry, which, once achieved, would result in a reduction of 5.6 gigatons of CO2 equivalent (GtCO2e) by 2020 and 26.8 GtCO2e by 2050.

Boosting subnational climate action through new climate governance

carbonn Climate Registry 2016-2017 report

The latest carbonn Climate Registry report, Boosting subnational climate action through new climate governance, shows how integrated reporting systems and multilevel governance can strengthen climate action. It is a snapshot of subnational climate data and shows how ambition can be raised when national governments integrate this data into holistic
climate planning.

The Climate Reporting Partnership can further facilitate this integrated model of climate governance by combining the efforts of CDP and the carbonn Climate Registry.
