About

Data Portal for Cities aids cities in advancing toward their climate objectives by providing essential data on emissions from buildings, transportation, and industries.

Globally, cities are focused on climate action planning, setting bold targets for the coming years to adapt and mitigate. Effective climate action planning starts with compiling a trustworthy greenhouse gas inventory, enabling decision-makers to understand how to best prioritize efforts.

Data Portal for Cities offers a comprehensive collection of estimated city-scale data across various sectors, readily accessible for download and utilization by cities. It also provides a simple, intuitive method for merging data from multiple sources into a unified emission inventory. In this process, cities can easily incorporate high-quality transportation data from Google and emission factors from CURB and IPCC.

Data is presented in a user-friendly format, ready for download and use in city planning, and is also displayed in interactive infographics, available to the public.

Data Portal for Cities is designed to help cities build comprehensive greenhouse gas (GHG) inventories using both their own data and the extensive datasets available through the platform. By signing up for free, cities can seamlessly integrate their local data with global datasets to generate accurate and actionable insights. The portal facilitates easy reporting to frameworks like CDP-ICLEI, and cities can request a City Profile to access Google transportation data, enhancing their inventory accuracy. Additionally, the portal allows cities to publish their GHG inventories and track their progress, fostering transparency and accountability in their climate action efforts.

The estimated data on the Data Portal for Cities are calculated using country-specific methods and data sets. These are based on established greenhouse gas accounting and data estimation methodologies, specifically developed for this purpose.

The Data Portal for Cities is developed by the Global Covenant of Mayors, ensuring high coherence with tools, like CIRIS and ASAP of C40 and reporting platforms like those of CDP, and ICLEI. Cities that have developed their climate inventory using C40’s tool, CIRIS, can effortlessly upload their data to the Data Portal for Cities for further edit and for publication to the public. Similarly, cities reporting through CDP and ICLEI can easily export inventories from the Data Portal for Cities for use in their reporting.
