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

This line chart visualizes 3 different degree scenarios (2°C, 4°C & 6°C) from 2010 to 2050 modeled using CDP and IEA ETP 2014 data alongside a target scenario that tracks Compact of States and Regions targets. Analysis is based on the 43 of 62 governments with region-wide GHG targets and inventories that have joined the Compact of States and Regions.
The scenarios reflect the following:
- 6DS: reflects a ‘business as usual’ projection that doesn't include national or state and regional commitments to reduce emissions;
- 4DS: reflects a 'reference case' projection that includes pre-2012 national commitments to reduce emissions;
- 2DS: reflects the pathway to implement a sustainable energy system in line with a 2° world; and,
- CTS: reflects state and regional commitments to reduce emissions.

This dataset contains names of cities, states and regions that reported in 2022. 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.

The Cities data is collected through CDP-ICLEI Track. 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’.

This visualisation shows the most frequently cited climate hazards by cities in 2022 disaggregated by the proportion of the population exposed to the hazard.

All data included in the dataset is self reported by cities through the 2022 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.

Complete open data set for companies that responded to the 2014 water questionnaire.

Through our investor initiative we target the largest listed companies in the world, as determined by market capitalization, in sectors for which water is a material issue. We currently cover the Global 500, S&P 500 and FTSE 100 indices as well as the largest companies in Australia, Japan and South Africa.

Water is also incorporated into CDP’s supply chain program. In this initiative, large multinational companies (our Supply Chain Members) issue CDP’s water questionnaire to a number of their suppliers. This exercise allows companies to investigate the water risk in their supply chain and gather vital information about water use outside their direct operations.

This year, we have invited approximately 2,300 companies to respond to CDP’s water questionnaire through our investor and supply chain initiatives. This data set excludes private responders.

State and regional government climate data is fundamental to delivering the Paris Agreement. Using the data that states and regions disclosed to CDP, we estimate that those that disclosed both a region-wide GHG emissions reduction target and a GHG inventory, are on course to meet the objectives of the Paris Agreement by 2020.
We incorporated the 2017 International Energy Agency scenarios to explore how collective emissions of states and regions change over time. This shows that disclosing states and regions are on average setting more ambitious targets than those set by their national counterparts. This demonstrates that present 2020 targets are sufficient to put states and regions on a trajectory for a 2 degree Celsius world. However, their long-term targets while more ambitious than their national counterparts, are not sufficient to keep the world below a 2 degree rise after 2020.
