The U.S. Postal Service is now the only mailing and shipping company worldwide that provides packaging supplies that are “Cradle to Cradle Certified.” This means that all 175 materials used by its 58 suppliers to make stamps and stamped products have been assessed, and meet requirements for, their impact on human and environmental health, recyclability and compostability.
The Postal Service says in 2009 it provided one billion eco-friendly mailing and shipping supplies to customers.
Technology used to create biodegradable or recyclable materials have allowed the agency’s sustainability initiatives to cut greenhouse gas production and to save money and resources. Specific achievements include a 10.8 trillion dollar reduction in British Thermal Units in energy use at their facilities since 2005, and $400 million dollars worth of savings in energy costs since 2007.
