Sony products consume electrical power while used in the hands of their owners, resulting in indirect emissions of CO2
. Having set a target for reducing annual energy consumption per product from product use of 30% from the fiscal year 2008 level by fiscal year 2015, Sony is promoting the incorporation of energy-saving features in a wide range of product categories. In fiscal year 2013, annual energy consumption per product was 31% lower than in fiscal year 2008. Particularly notable reductions were achieved for LCD televisions, Blu-ray Disc™ players and game consoles. Sony's total CO2
emissions over the entire life cycle of all products sold in fiscal year 2013 were approximately 14.13 million tons, 10% lower than for products sold in fiscal year 2012, thanks to the incorporation of energy-saving features into products and to a decline in sales volume.
- Note: In theory, emissions during product use in the current fiscal year should be calculated from the total quantity of electrical power consumed by previously sold Sony products that are still in use by consumers in the current fiscal year. However, given the difficulty of determining how many previously sold Sony products are still in use by consumers of the total number of Sony products sold to date, Sony uses the total quantity of electrical power consumed while in use over the lifetime of Sony products sold in the current fiscal year as an indicator for CO2 emissions during use.
