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

This data was collected in partnership by CDP and ICLEI - Local Governments for Sustainability.

The dataset contains all city-wide emissions reduction targets publicly disclosed in 2018 and 2019.

Please note that the 2018 data on city-wide emissions reduction targets is still in the process of being updated. If you have any questions, please contact cities@cdp.net.

CDP's water program motivates companies to disclose and reduce their environmental impacts by using the power of investors and customers. The data CDP collects help influential decision makers to reduce risk, capitalize on opportunities and drive action towards a more sustainable world. This dataset comes from question W1.4a asking companies to describe the detrimental impacts experienced by their organization related to water in the reporting year.

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)

CDP's water program motivates companies to disclose and reduce their environmental impacts by using the power of investors and customers. The data CDP collects help influential decision makers to reduce risk, capitalize on opportunities and drive action towards a more sustainable world. This dataset comes from question W3.2d asking companies to list the inherent water risks that could generate a substantive change in their business, operations, revenue or expenditure, the potential impact to their supply chain and the strategies to mitigate them.

Dataset includes data and analysis for 4 scenarios for the Compact of States and Regions from 2010 to 2050. The scenarios incorporate IEA data ETP 2014 data.

The Compact of States and Regions is run by CDP and The Climate Group.

CDP's water program motivates companies to disclose and reduce their environmental impacts by using the power of investors and customers. The data CDP collects help influential decision makers to reduce risk, capitalize on opportunities and drive action towards a more sustainable world. This dataset comes from question W3.2c asking companies to list the inherent water risks that could generate a substantive change in their business, operations, revenue or expenditure, the potential impact to their direct operations and the strategies to mitigate them.

List of incentives that city governments provide to reduce greenhouse gas emissions in their cities. Contains the type of incentive (monetary, recognition, etc), the potential beneficiary, and a description.

This dataset contains 2021 data on cities' adaptation actions related to water security risks. The data was reported by cities through the CDP-ICLEI Unified Reporting System in 2021 in response to question 14.3 - "Please select the actions you are taking to reduce the risks to your city’s water security" - in the 2021 CDP 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 data is collected through the CDP-ICLEI Unified Reporting System. When using this data, please cite both organisations using the following wording: ‘This data was collected in partnership by CDP and ICLEI - Local Governments for Sustainability’.
