"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.
