Sustainability index

CDP is an international, not-for-profit organization providing the only global system for companies and cities to measure, disclose, manage and share vital environmental information.



The Carbon Disclosure Project (CDP) allows businesses that disclose their GHG emissions to benchmark their performance. Nearly 2,000 businesses participated worldwide in 2014. 

In 2014, we scored an impressive 94A in the climate change programme, and are one of only two infrastructure companies to make it onto the CDP's 2014 Climate Performance Leadership Index.
