This dataset contains 2023 data for cities. All data included in the dataset is self reported by cities through the 2023 Cities Questionnaire. Please note that the reporting platform remains open for submissions until the end of the year and the dataset is updated daily to reflect new submissions. Guidance on how to read this dataset is available in the Open Data Portal User Guide (Header Menu > Explore). Access more information on cities reporting, including questionnaire guidance, at https://www.cdp.net/en/guidance/guidance-for-cities.

Please note that this dataset is too large to download to Excel. If you wish to export the data, go to View Data > More Views then select a filtered view. There are two types of views: 1) regional, 2) questionnaire sections.

Please note that this dataset may contain data from cities or, in some instances, groups of cities at different administrative levels. This includes metropolitan areas, combined authorities, and some regional councils.

When using the inventory data for aggregation, comparison and trend analysis, please note that the inventory data is based on non-verified self-reported city inputs. The reported inventory may not include all emission sources within the city boundary.
