The dataset contains 2021 data on cities' water security risks, reported by cities through the CDP-ICLEI Unified Reporting System in response to question 14.2a ("Please identify the risks to your city’s water security as well as the timescale and level of risk.") in the 2021 Cities questionnaire. View cities questionnaire guidance at https://www.cdp.net/en/guidance/guidance-for-cities. Please contact cities@cdp.net if you have any questions.

This dataset contains public data on cities adaptation actions, as reported by cities and local authorities through CDP-ICLEI Track in 2022. The platform remains open and the dataset is updated daily to reflect new submissions.

This dataset combines reported emissions and population data with external datasets:
- City Population, from the Geonames database
- Country GDP per capita from the World Bank
- Country emissions per capita from EDGAR

The results from the following data quality checks are displayed:
- Population Check - Comparison between reported populations and figures from the Geonames database
- Emissions Check 1 – A multiple regression model is used to identify statistical outliers (using city population and country GDP per capita)
- Emissions Check 2 - A comparison between city per capita emissions and country per capita emissions.

Field names:
geoid - A unique identifier corresponding to the city's record in the Geonames database
account_id - The CRM organisation ID
org_name - The CRM organisation name
rep.population - The reported population
rep.population.source - The source of the reported population. The population data used is primarily from question 4.5, as this figure corresponds to the year the inventory was taken. If no population is provided in question 4.5, then question 0.5 (current population) is used instead.
geo.population - The city population provided in the Geonames database (used to verify the reported population)
effective.population - After the population check has been carried out, the 'effective population' is defined for use in the subsequent emissions checks. If a city passes the population check, their reported data is used here, otherwise external data is used (i.e. from the Geonames database)
has.inventory - This is the city's response to question 4.0 in the 2019 questionnaire, which asks the city to state whether they have an emissions inventory to report
inventory.type - If the city has an emissions inventory, this field specifies the format that this inventory is provided in
effective.s1.s2.sum - The total scope 1 + scope 2 emissions reported by the city. This is obtained from either question 4.6a or 4.6b, depending on whether the city followed the CRF, or GPC
city.emissions.per.cap - The city's effective.s1.s2.sum is divided by the effective.population to calculate the emissions per capita for that city
country_co2e_per_capita_2012 - This is country level per capita emissions data obtained from: EDGAR’s Global Greenhouse Gas Emissions from 1970 to 2012 (EDGARv4.3.2 dataset). While the data used is from 2012, this is the most recent dataset available which includes all greenhouse gases. More recent datasets are available for CO2 alone, however this is not consistent with the cities' data, which generally includes other GHGs too. Link here: https://edgar.jrc.ec.europa.eu/overview.php?v=CO2andGHG1970-2016&dst=GHGpc
country.GDP.pc.2018 - This is country level GDP per capita in 2018 in US$, obtained from the World Bank. Link here: https://data.worldbank.org/indicator/NY.GDP.PCAP.KD
flag.population - The data quality flag identifying cities whose reported population differs from the external population by +/- 50%
flag.emissions.check1.statistical.outliers - The data quality flag identifying cities whose emissions appear to be anomalously high or low, based on a statistical regression with population and country GDP
flag.emissions.check2.per.capita.country - The data quality flag identifying cities whose per capita emissions differ greatly from the country per capita emissions (a generous theshold of 10x is used, as some variation is expected)

Annual city-wide emissions for more than 100 global cities. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

This dataset includes the detailed responses of publicly disclosing African cities in 2019. For a summary of the cities, please refer to the dataset titled "2019 African Cities Summary".

Emissions reduction targets for all reporting cities in 2015. Includes baseline emissions, baseline year, percentage reduction target, and other details. Some cities report multiple targets.

This dataset contains the complete data for 2021 on cities that reported emissions inventories using either a regional, country or city specific methodology or another methodology not listed in question 4.3 of the questionnaire. The data in the dataset is based on responses to question 4.6f in the 2021 Cities questionnaire, as reported by cities and local authorities through the CDP-ICLEI Unified Reporting System.

This dataset includes the summary of publicly disclosing African cities in 2019. For detailed responses of the cities, please refer to the dataset titled "2019 African Cities Response".

This dataset contains 2021 data on cities' water resources management strategies. The data was reported by cities through the CDP-ICLEI Unified Reporting System in 2021 in response to question 14.4a - "Please provide more information on your city’s public Water Resource Management strategy" - in the 2021 CDP Cities questionnaire.

Risks from climate change identified and reported by city governments. Includes a list of the anticipated effects of climate change, timescale, and seriousness
