In 2009, Autodesk was selected for inclusion in the Carbon Disclosure Project's Carbon Disclosure Leadership Index (CDLI), a global ranking of companies' carbon disclosure practices. Autodesk was the only software company selected for this index, and was ranked sixth of 100 IT companies.
The Carbon Disclosure Project is an independent not-for-profit organization that holds one of the largest databases of corporate climate change information in the world. The data is obtained from responses to the organization’s annual Information Requests, issued on behalf of institutional investors, purchasing organizations and government bodies. Since its formation in 2000, the organization has become the gold standard for carbon disclosure methodology and process, providing primary climate change data to the global market place.
