In 2015 companies were invited to respond to two new questions in CDP's annual global climate change questionnaire: firstly to say whether their board supports an international agreement between governments on climate change, and secondly to describe their board's position on what an effective agreement would mean for their company and the activities they are taking to deliver.

Analysis of the responses shows that companies which have formulated an opinion on a global climate deal are overwhelmingly in support of an ambitious agreement in Paris. More than 800 of the largest listed companies around the world favour a global deal to tackle climate change.
