The Carbon Disclosure Project is an independent nonprofit organization supporting greenhouse gas emissions reduction and sustainable water use. The scores released in its annual Climate Change Report are regarded as a measure of climate mitigation performance and quality of disclosure. In addition to a score, a grade is awarded on a scale of E to A. Norfolk Southern's grade for 2012 is B, matching its 2011 grade.
"We are pleased to have demonstrated continuous improvement in our disclosure score during the years we have participated in the Carbon Disclosure Project," said Blair Wimbush, NS vice president real estate and corporate sustainability officer.
"The 2012 result exceeded our goal and puts Norfolk Southern in the high range of companies disclosing, well above the average disclosure score of 70. This positive trend complements our sustainability goal to achieve industry leadership in fuel conservation, emissions reduction, efficient energy use, recycling, use of renewable materials, and environmental partnerships," Wimbush said.
Among efforts to lessen the company's environmental impact, Norfolk Southern has attained 60% of a five-year goal to reduce emissions per revenue ton-mile 10% by 2014. With reforestation playing a key role in its carbon mitigation strategy, the company has partnered with Green Trees to plant more than 6 million trees in the Mississippi Alluvial Valley.
Last week CSX Corp. announced its own Carbon Disclosure Project accomplishments, highlighting the push by the nation's Class I railroads to improve and publicly note their environmental and energy efficiency.
