European companies are working harder at disclosing their financial risks associated with greenhouse gas emissions than North American companies, according to an annual report. Every year for the last decade, the Carbon Disclosure Project has asked 500 global companies on behalf of 534 institutional investors representing more than $64 trillion of assets under management, to measure and report their emissions. It also asks them to assess how climate change would affect their future financial health. In this year's survey, Europe had 20 percent of the best performing companies in the CDP's global list of 500 companies who are taking action to outline the risks, while North America only had 6 percent...CDP said the global companies that disclosed their risks the best in 2010 were Siemens AG, Deutsche Post, BASF, Bayer and Samsung Electronics.
