“Raising Global Level of Ambition Through Local Climate Action”



Key Achievements of Local Government Climate Roadmap Process


The Compact of Mayors

United Nations Secretary-General Ban Ki-moon and UN Special Envoy for Cities and Climate Change Michael R. Bloomberg announced the launch of a global Compact of Mayors, the world’s largest effort for cities to fight climate change. The Compact will enable cities to publically commit to deep GHG emissions reductions; make existing targets and plans public; and report on their progress annually, using a newly-standardized measurement system that is compatible with international practices. Through this effort, cities will be choosing to meet the same requirements proposed for the international climate negotiations that will lead to a global climate treaty in 2015. (Read the Compact here)

Under the Compact, local emissions data will be collected through existing city platforms, including partner platform CDP Cities, and will be made publically available through ICLEI’s platform, the carbonn Climate Registry

People's Climate March

On September 21st, the People's Climate March was the largest and most diverse mobilization for climate action in history, situated in New York and globally. To show their commitment to protecting people’s climate, a number of Mayors joined the march under the banner, “People’s Climate, Mayors Commit”. This is in line with the vision laid out in the global advocacy of the Local Government Climate Roadmap. ICLEI took part by bringing a delegation of mayors from pioneering cities to participate in the New York City March.

The Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC)

Upon conclusion of a pilot phase featuring the participation of about 30 cities around the world and several training workshops in Latin America, Asia, Africa and Europe the Protocol entered its final phase in May. The GPC version 2.0 was made open for public comment from July 2014. A formal launch of the GPC is planned to be announced and presented during the COP in Lima in December 2014.

The GPC offers a methodology to help cities and local communities of all sizes and geographies measure and report their GHG emissions in a standardized way, thus establishing a single minimum global standard for community‐scale greenhouse gas (GHG) emissions measurement. Read More


Published Reports

"Climate Change: Implications for Cities"

Key Findings from the Intergovernmental Panel on Climate Change Fifth Assessment Report (Cities Summary)

The Cities Summary briefing, published jointly by ICLEI, and the University of Cambridge’s Institute for Sustainability Leadership and Judge Business School, with the support of the European Climate Foundation, demonstrates the urgency for climate change mitigation (and low emission development), adaptation, and the effects that climate change will have on urban life.

carbonn Climate Registry Report

2013 Annual Report (click here to read in full)

The new carbonn Climate Registry (cCR) report reveals that global voluntary reporting of local climate action triggers trustworthiness, access to finance and citizen engagement. The registry is the world´s leading reporting platform to enhance transparency, accountability and credibility of climate action of local and subnational governments. It is designated as the central repository of the Compact of Mayors launched at the Climate Summit 2014.

(The cCR was previously called the carbonn Cities Climate Report)


UNFCC: ADP Sessions

ADP2.6 - October 2014 - Bonn, Germany

Progress of local government climate action since June 2014 was showcased in an oral presentation at the ADP Stocktaking Meeting (Technical Expert Meeting on Urban Environment), which included proposals in Workstream 1 (2015 agreement) and Workstream 2 (pre-2020 ambition) for the workplan agenda – to be adopted as a protocol at the COP21 in Paris, France 2015.

Co-Chairs released a revised draft text (November 2014) that includes paragraph provisions giving recognition, engagement and empowerment to local and subnational actors, particularly in paragraph 37.a,b. The draft text will form the basis of negotiations at COP20 in December 2014, in the ADP 2.7 session.

ADP2.5 - June 2014 - Bonn, Germany

ICLEI proposed to the Parties and the UNFCCC Secretariat a draft agenda for the June Forum and requested a special category on “Cities and Subnational action” within the side events list. This second point has already come into effect.

Both the Technical Expert Meeting (TEM) and June Forum are recognized as concrete advances on the proposals contained in the 2013 Nantes Declaration of Mayors and Subnational Leaders on Climate Change, which defines the strategy of the Local Government Climate Roadmap towards Paris 2015.

ICLEI’s carbonn Center will be supporting the activities of the Roadmap at the ADP2.5, for example by providing relevant information on local climate action such as data from the carbonn Cities Climate Registry (cCCR) with the latest annual analysis report to be officially presented on this occasion (for a sneak preview visit the carbonn Cities Climate Registry here).

ADP2.4 - March 2014 - Bonn, Germany

The ADP2.4 sessions concluded with a decision to convene a Technical Expert Meeting on urbanization during the UN June Climate Conference to be held on 4-15 June in Bonn. Why is this important? This new expert meeting will complement the June Forum on sharing experiences among Parties on mitigation and adaptation actions of cities and subnational authorities, as one of the outcomes of the UN Warsaw Climate Conference (COP19) in December 2013 for local and subnational governments.

"Friends of Cities" group at the UNFCCC

The creation of a “Friends of Cities” group among national governments at the UNFCCC, ensuring concrete outcomes for engagement of local and subnational governments in global climate regime through partnerships and action plans, strengthening the institutional framework of local governments and municipal authorities constituency are integral parts of this renewed global climate advocacy strategy

Nantes Declaration of Local and Subnational Government on Climate Change

The adoption of the Declaration during the World Mayors Summit on Climate Change marked the start of a new phase for the Local Government Climate Roadmap

COP19 Warsaw

At the UN Climate Change Conference in Warsaw (COP19/CMP9), countries decided to advance the engagement of local governments in the global climate regime. The decisions include (1) facilitating the exchange of experiences and best practices between cities and subnational authorities in identifying and implementing opportunities to mitigate greenhouse gas emissions and adapt to the adverse impacts of climate change, and (2) convening a specific forum as part of the UN Bonn Climate Conference in June 2014.


Global Protocol for Community Scale GHG Emissions

WRI is developing a GHG inventory standard to guide city- and community-scale GHG accounting practices worldwide. As a first step, WRI partnered with ICLEI – Local Governments for Sustainability (ICLEI), C40 Cities Climate Leadership Group (C40), the World Bank, UN-HABITAT, and United Nations Environment Program (UNEP to develop the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC).


Durban Adaptation Charter

The Durban Adaptation Charter commits Local Governments to local climate action in their jurisdiction that will assist their communities to respond to and cope with climate change risks thereby reducing vulnerability.


Global Cities Covenant on Climate - the Mexico City Pact

The Pact is a voluntary initiative of mayors and local authority representatives that consists of ten action points. By signing the Pact, signatories commit to advance local climate action, including the reduction of emissions, adaptation to the impacts of climate change and fostering city-to-city cooperation.

carbonn Climate Registry

The carbonn Climate Registry is the leading global reporting platform of local climate action. It is designated as the central repository of the Compact of Mayors launched at the Climate Summit 2014.

COP 16 Cancun

The Local Government Climate Roadmap reached a milestone achievement in 2010 with the adoption of the Cancun Agreements (Dec.1/CP16) in which para.7 recognizes local and subnational governments as governmental stakeholders.
