Energy Saving

The Panasonic Group has initiated a new index, "size of contribution in reducing CO2 emissions" since FY2011 and tackled continued activities to improve our energy saving constitution. The Company achieved 940,000 tons of size of contribution in reducing CO2 emissions in FY2012.

Size of contribution in reducing CO2 emissions

The size of contribution in reducing CO2 emissions is defined by the following formula;
CO2 reduction contribution during the applicable fiscal year (base: FY2006) = (Basic unit per production of FY2006 - Basic unit per production of the applicable fiscal year) X Production output of the applicable fiscal year
