The CDP (which was called the Carbon Disclosure Project until the end of 2012) is a not-for-profit organization which aim is to study the implications of climate change for the world's principal publicly traded companies. The CDP has a permanent administrative office based in London and a staff of 50.

Since 2003, the CDP has conducted an annual survey to collect information on greenhouse gas (GHG) emissions by companies. Its questionnaire of more than 100 questions has included a specific Oil & Gas section since 2010.

In 2010, the CDP expanded its scope and now conducts an annual survey on water management by companies, called CDP Water, and, since 2013, another on their impact on forests: CDP Forests.

Total has been responding to the CDP's annual survey on greenhouse gas emissions since 2003. Our responses are published at the CDP site.
