C&S Wholesale Grocers Inc., Keene, N.H., has undertaken a comprehensive initiative to reduce its environmental carbon footprint.

"Environmental sustainability is important to us," said Scott Charlton, executive vice president of operations at C&S, in a news release from the company. "We're gathering and interpreting data and using it to evaluate improvements in our business operations."

According to the release, C&S is undertaking the initiatives by addressing issues in six areas - energy audits, buildings, green power, recycling and waste management, distribution fleet and carbon sequestration.

C&S is performing energy audits and sustainability analyses of all its buildings, including the collection of data on refrigeration/air conditioning, electricity, propane, natural gas and water use, according to the release. The company also is implementing energy efficiency measures in all its warehouses.

More than 40% of the company's energy at its distribution centers in the Buffalo, N.Y., area comes from hydropower, and the company is looking into adding green power to other facilities, according to the release.

C&S employees are encouraged to recycle and reduce waste of paper, cardboard, wood pallets, plastic wrap and electronics. According to the release, about 540,000 pounds of office paper were recycled from C&S warehouses in New England in 2008.

The company continues to invest in network optimization technology for its fleet of trucks to reduce miles traveled and estimates it will save 400,000 gallons of fuel in a 12-month period between 2008 and 2009, according to the release.

C&S also has partnered with The Conservation Fund to offset the annual carbon emissions of its corporate headquarters, including the estimated round-trip commutes of its employees.
