Corporate Environmental Action Tracker Methodology
Overview
The Corporate Environmental Action Tracker (CEAT) shows, at an aggregated level, the status of action on climate by companies disclosing through CDP. The tracker gives companies, capital markets, policymakers and civil society access to insights from the world’s largest environmental data set to help inform decisions and understand corporate progress towards and potential impact of current commitments disclosed through CDP.
Indicators
Each indicator is designed to assess climate action, based on corporate disclosure. In the tracker we differentiate between category-based indicators in Steps 1 to 5 and the impact indicators of Step 6.
Steps 1 to 5: Category indicators

For each indicator, each company is assigned a single category, based on their responses to certain questions, or combinations of questions, in the questionnaire.
The companies are then aggregated in their categories.
Example:
For the indicator Value chain engagement in Step 4: Strategy and Transition Plan, we have defined five possible categories:
Engaging with suppliers and customers
Engaging with suppliers only
Engaging with customer only
No engagement
Limited data
These five categories are mapped to the answers to question C12.1 of the CDP climate change questionnaire [4] “Do you engage with your value chain on climate-related issues?” (see the detailed section on the Value chain indicator for details on this mapping). Every company is assigned to one of the five categories above.
In the 2023 disclosure cycle, shown as reporting year 2022 on the tracker, the following numbers of companies were assigned to each bucket. As the indicator is mainly shown in terms of the emissions of the companies contained in these buckets (rather than the number of companies), only companies that passed the emissions filtering step are included.
Category | Mt CO2e | # companies |
---|---|---|
Suppliers and customers | ~5,700 | ~4,800 |
Suppliers only | ~1,400 | ~1,800 |
Customers only | ~1,300 | ~2,600 |
Not engaging | ~600 | ~2,900 |
Limited data | ~40 | ~260 |
Total | ~9,000 | ~12,300 |
The following section explains how the category values at company-level were derived for each indicator.
Data preparation
Emissions filtering process
We applied different filtering steps to the emissions per company, which formed the basis for all category-based indicators at Global, Country and Sector level. The purpose of the filtering process was to remove potential incorrectly reported emissions values from the aggregation and submissions for very different reporting periods, which could reduce the accuracy of the final result.
The following steps were applied:
External sources
In addition to CDP questionnaire responses and information on company targets from SBTi, we used the following data sources to calculate the indicators.

FAQ
Glossary
Level: We show data at four different levels in the tracker: Global, Country, Sector, Index. The country-level results only exist for the disclosure indicator on Step 1.
MtCO2e: Megatonnes (106 metric tonnes) of carbon dioxide equivalent (ie including several/all greenhouse gases, rebased according to their global warming potential)
Reporting year: The year shown on the tracker. This is the calendar year preceding the questionnaire/disclosure year which the analysis is based on. For example, the data shown as reporting year 2021 derived from questionnaire responses from the 2022 disclosure cycle.
Sector: Sectors in the Tracker, to the extent possible, are based on the IPCC Common Reporting Framework used by the UNFCCC. However, several datasets had to be combined to allow better matching of the national inventories with the corporate inventory data reported through CDP. See 'Where does the data in the tracker come from?' above, for more information on the sector definitions. The sectoral emissions, and their aggregation, are used to calculate the proportion of total emissions globally/per sector disclosed through CDP.
Footnotes
Note that although all companies’ responses received by 1 October in the disclosure cycle are in principle considered, the emissions indicators only contain responses from companies that report for an accounting year no more than 2 years preceding the disclosure cycle and which pass the emissions filtering process.
‘Total emissions’ here refers to companies’ Scope 1 emissions only. Aggregated Scope 1 values are the main values displayed in all emissions-based graphs in the tracker. Aggregation taking into account Scope 2 emissions as well are shown in the tool tips which appear when hovering with the cursor over an emissions graph data point.
In 2022, the revenue data for five FTSE 100 companies and one S&P 500 company could not be obtained, and therefore they had to be excluded from all analyses based on revenue shares.
The question numbers quoted in the methodology can be found in the 2020 to 2023 climate questionnaires.
