The annual report on climate change and carbon emission performance of the world's largest 500 companies released by Carbon Disclosure Project at Climate Week in New York reveals that these companies account for 11% of global emissions.

In the 10 years since the launch of the Carbon Disclosure Project (CDP), the quality and quantity of reporting on climate change have increased dramatically. CDP is now looking beyond disclosure to identify the companies that are taking active steps toward a low-carbon economy. In 2010, the CDP asked the world’s 500 largest public companies in the FTSE Global Equity Index Series (Global 500) more directly than ever to demonstrate that they are taking action on climate change. This report, prepared by CDP’s global adviser, PricewaterhouseCoopers (PwC), analyzes the responses from those corporations. For this report particular attention was paid to ways that organizations in every sector are capitalizing on commercial opportunities —in particular, those presented by emissions reductions.
