XBRL > Learn more about the climate change reporting taxonomy (CCRT)

eXtensible Business Reporting Language, or XBRL as it is more commonly known, is about to transform the way companies report their climate change information.

XBRL is already widely used for financial reporting in the United States, where it is mandated by the Securities and Exchange Commission (SEC) and in the UK where company accounts and tax returns must be submitted in XBRL electronic format. Now CDP and the Climate Disclosure Standards Board (CDSB) are working with a number of organizations to harness this technology and create an XBRL climate change reporting taxonomy. This will make climate disclosure easier and more streamlined for companies.

Together with CDP’s transformative system and CDSB’s climate change reporting framework we will provide a comprehensive toolkit for standardized, investor-quality climate change disclosure.

"I welcome the efforts of CDP and CDSB to establish the climate change reporting taxonomy and that the ITA (Interoperable Taxonomy Architecture) framework is being followed to produce it. This will bring power and advantages for users all around the globe that wish to adopt it and integrate climate change into their main stream fillings using International Financial Reporting Standards or other ITA compliant taxonomies."

— Olivier Servais, Director XBRL Activities, International Accounting Standards Board (IASB)

Would you like to be a pioneer in the evolution of technology and standards to facilitate the exchange and analysis of standardized climate change information?

We are looking for a limited number of companies to support while they trial the new climate change reporting taxonomy. This will help us to progress climate change reporting and position you as a leader. If you are interested, please contact our expert working group or your CDP account manager for further details.
