In 2010, the company published a Carbon Footprint report. This included results of a survey sent to 86 suppliers that provide raw material to nine Sun sites. Of the 26 suppliers that answered the 2010 survey, 14 had a sustainability policy; seven quoted carbon emissions of their products; and 10 expected to collect carbon footprint information in the next 12 months.

The response rate and quality of the responses was not enough to use the actual data collected to extend the company’s carbon footprint study to raw materials, Sun said. The company says that it will pursue efforts to learn more about the environmental impact of raw materials.
