Consumption based GHG emissions of C40 cities
New research by C40 Cities, the University of Leeds, University of New South Wales, and Arup examines the greenhouse gas (GHG) emissions associated with goods and services consumed by residents of cities such as food, clothing, electronic equipment, airplane travel, delivery trucks and construction industries. The findings reveal a detailed picture of the supply chains and sphere of impact that mayors, businesses and citizens can potentially influence with their climate action.
Opportunity 2030: The benefits of Climate Action in Cities
The findings from this report present an evidence base for accelerated action for climate change mitigation measures. It equips city, national governments, private sector and citizens with several reasons for a joint collaborative effort toward the goals of low carbon development.
This report will be followed-up by an extended work, complementing this first analysis to include assessments at the global scale. The results of this second phase of the work will be made available by the end of the third quarter of 2018, including through an online interactive dashboard.
All methodological details, assumptions and limitations of the Opportunity 2030 project analysis are published in an accompanying methodological report, available online. Readers are encouraged to engage in, critically review and further build upon the methodologies and results in this report, and to make use of the content where possible as a tool for moving towards more holistic and participatory planning for sustainable development in cities.

Urban Climate Action Impacts Framework: A Framework Describing and Measuring the Wider Impacts of Urban Climate Action
This document presents an Urban Climate Action Impacts Framework (UCAIF or ‘the Framework’) that can be applied when exploring the wider impact of city climate action, and builds on the work started by C40 and LSE. The report functions as a user guide with common principles, taxonomy and guidelines for approaching the mapping and assessment of those wider impacts. The outputs of the work aim to catalyse medium-term development of the tools, resources and evidence cities need to make the case for climate action by linking that climate action to the other priorities they face.
Electric Buses in Cities: Driving Towards Cleaner Air and Lower CO2
Cities around the world are introducing electric buses, driven by growing concerns over urban air quality, carbon emissions and potential operational cost savings. The timing is now right for cities to start shifting to electrified transport but there are still several barriers to widespread adoption.
Focused acceleration: A strategic approach to climate action in cities to 2030
This Report identifies 12 opportunities that have the greatest potential in most global cities to curb emissions and put cities on a 1.5°C pathway through 2030.
Measurement & Planning
Consistent measurement is the first step in effective management. The Measurement and Planning Initiative, housed within C40 Research, focuses on building capacity in member cities to tackle climate change strategically through the measurement of GHG emissions and climate impacts, annual reporting of climate data, and development of climate action plans. These efforts are provided through three workstreams: Measurement; Reporting; and Climate Risk and Adaptation Framework and Taxonomy. Most recently, the Initiative launched an interactive dashboard with four unique ways to explore historical GHG emissions of C40 cities reported via the standardized GPC protocol.
Case Study Library
C40 case studies highlight the wealth of sustainable and urban innovation underway in our member cities. We invite you to explore the library to discover topics of interest to your city.
In the lead-up to COP21 in Paris, C40 and Sustainia have a shared mission to showcase 100 leading city solutions to climate change. The resulting publication, Cities100, will highlight the need for adapting new policies and celebrate the range of possible actions.
Deadline 2020: Special Report on U.S. Cities
Deadline 2020: How U.S. cities will get the job done is an analysis of the contribution U.S. cities can make to delivering the Paris Agreement objective of limiting global temperature rise to 1.5 degrees Celsius. This report and its findings reinforce the positive influence and action seen from U.S. C40 cities to date, with plenty of reasons to be confident that this will continue.

Urban Efficiency II: Seven Innovative City Programmes for Existing Building Energy Efficiency
Urban Efficiency II: Seven Innovative City Programmes for Existing Building Energy Efficiency builds on research in the successful predecessor “Urban Efficiency” Report and captures seven new detailed city case studies from C40 member cities. It is primarily targeted at city-level policy makers and decision makers across the world. The report increases the resource and evidence base available to support cities understanding of the characteristics and impact of innovative city programmes emerging across C40 cities, that advance operational energy efficiency and retrofitting in existing, privately owned buildings.
Open Data Portal
The Open Data Portal provides direct, interactive access to the wealth of statistical information provided annually by C40 cities. Through the Open Data Portal, it is possible to access and investigate a number of data sets on C40 cities, including GHG Emissions Inventories, Reduction Targets, and Citywide Risks. The Open Data Portal is another step towards providing increased access and availability regarding the impact and ambition of C40 cities.
The Low Carbon Investment Landscape in C40 Cities
The Low Carbon Investment Landscape in C40 Cities is an analysis of the sustainable infrastructure projects currently in development across C40 cities. The pipeline is based on self-reported data from C40 cities and highlights the tremendous potential for investment and collaboration with the private sector to deliver a climate safe future.
