JACKSONVILLE, Fla., Sept. 26, 2013 /PRNewswire/ -- CSX Corporation (NYSE:CSX) announced that the company was recognized on the CDP S&P 500 Carbon Performance Leadership Index and was included among just five industrial companies worldwide in the CDP Global 500 Climate Performance Leadership Index. These distinctions highlight CSX's steadfast commitment to reducing carbon emissions and fuel use. "Environmental responsibility and accountability are part of the fabric of our daily operations," says Michael Ward, CSX chairman, president and chief executive officer. "As our business grows, so does our investment in sustainable operations and efficient technology. CSX is proud to be recognized for its efforts and will continue to make the environment a priority for the sustainable future of the company and the benefit of those we serve." The 2013 CDP S&P 500 report prominently features CSX's National Gateway project, an $850 million public-private rail infrastructure and intermodal terminal capacity project that is projected to eliminate up to 20 million tons of carbon emissions and save nearly 2 billion gallons of fuel. Intermodal shipments now make up nearly 40 percent of the company's shipments by volume and capitalize on the environmental efficiency of freight rail. CSX raised its performance score among S&P 500 industrial companies from a B to an A, and was the only railroad recognized among five industrial companies on the Climate Performance Leadership Index (CPLI). The CPLI recognizes those companies with superior emissions performance. Paul Simpson, CEO of CDP, comments, "Natural resource scarcity is intensifying, the scientific case for action to mitigate climate change is strengthening and the number of investors requesting corporate action on climate change through CDP is continually increasing. We congratulate companies in the Climate Performance Leadership Index for their pioneering efforts to combat climate change and grow low carbon economies at this critical time." On the 2013 Global Climate Performance Leadership Index, which evaluates the sustainability efforts and successes of the world's 500 largest companies, CSX received the ninth highest score among 40 industrial companies.
