Norfolk Southern Corp. wants to chart its "going green" efforts on the World Wide Web. Yesterday, the Class I announced it launched a Web site at www.nscorp.com/footprints to share and gather information on the railroad's sustainability projects.

Also accessible on NS' home page under a "learn more about NS and the environment" application, the site outlines the Class I's sustainability initiatives, such as developing public-private partnerships to improve the nation's rail network while supporting the economy, minimizing use of natural resources, and reducing, reusing and finding alternatives for commonly used railroad materials.

The site also features NS' "Green Machine" carbon footprint analyzer unveiled last month. The Green Machine calculates how shippers can reduce emissions if rail becomes a larger component of their supply chains. In addition, the site includes a "Your Ideas" area through which visitors can submit sustainability ideas to the Class I.

"An important part of sustainability on the railroad involves employee, customer and supplier input," said F. Blair Wimbush, NS' vice president of real estate and corporate sustainability officer, in a prepared statement.
