*1 From fiscal 2017, the size of contribution in reducing CO2 emissions and the amount of CO2 emissions for household air conditioners are calculated based on the updated standards (e.g. JIS) employed in calculating the annual power consumption. Based on the previous calculation method, the amount of size of direct contribution in reducing CO2 emissions in fiscal 2017 is 38.14 million tons, and the amount of CO2 emissions is 82.12 million tons.
*2 Lifetime CO2 emissions from major products*3 with large amounts of energy use.
Lifetime CO2 emissions = Annual power consumption of a model sold*4 x Sales quantity x Product life*5 x CO2 emission factor*6
*3 Household air conditioners, commercial air conditioners, fluorescent lamps, LED lamps, household refrigerators, commercial refrigerators, LCD TVs, washing/drying machines, fully-automatic washing machines, clothes dryers, dish washer and dryers, IH cooking heaters, EcoCute, bathroom ventilator-driers, humidifiers, dehumidifiers, air purifiers, extractor fans, vending machines, electronic rice cookers, microwave ovens, warm-water washing toilets, clothing irons, hair dryers, under-rug heaters, vacuum cleaners, electric thermal pots, extractor hoods, telephones, security cameras, projectors, etc.
*4 For each product category, the model that was sold in the largest quantity in the region was selected.
*5 Number of years during which spare parts for the product are available (defined by Panasonic).
*6 Regional CO2 emission factors (kg-CO2/kWh) used: 0.410 (Japan); 0.487 (Europe); 0.579 (North America); 0.740 (China & Northeast Asia); 0.927 (India & South Asia); 0.527 (Southeast Asia & Oceania); 0.332 (Latin America); and 0.599 (Middle East & Africa).
