Cities house half the world’s population but represent almost two-thirds of global energy demand and 70% of carbon emissions from the energy sector. Therefore, transition to a sustainable economy will be won or lost in our cities. Explore how cities across the globe are working to measure their city-wide emissions, a vital first step towards taking ambitious climate action.

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

CDP has created a 'clean & complete dataset' for the 2015 Carbon Action sample of companies - a group of the highest emitting public companies from the most energy-intensive industries. The full dataset covers Scope 1 and Scope 2 emissions from 2009-2014 and 10 Categories of Scope 3 emissions for the most recent accounting year (excluded from this public dataset). Production involved applying methods for the quality assessment of self-reported data and integration of CSR report data, as well as the development and application of models to estimate emissions for companies that do not report them.

This public dataset represents a subset of industries, companies and years of the full version. All users can interact with estimates and model details. The full dataset is freely available to CDP's investor signatories or can be purchased by others.

The full Methodology and a selection of models can be accessed from https://www.cdp.net/en-US/Programmes/Pages/ghg-emissions-dataset.aspx

CDP’s new infographic report ‘Who’s tackling urban water challenges’, produced in partnership with AECOM, the global infrastructure firm, and funded by Bloomberg Philanthropies, shows the first and most comprehensive dataset of global water action by cities and companies produced to date. Using information gathered from 569 cities and 1,432 companies, each reporting their water management activity, it illustrates how global cities and companies are responding to the escalating challenge of climate change and urban population growth.

Cities are increasingly reporting that they are powered by renewable electricity. CDP holds information from over 570 of the world's cities and over 100 cities are now getting at least 70% of their electricity from renewable sources such as hydro, geothermal, solar and wind.

This dataset has been compiled of data reported by cities in 2015, 2016 and 2017 in response to our annual questionnaire. Cities responded to the question: "Please indicate the energy mix of your electricity consumed at the city-wide scale."
