Under the Green Management 2015 mid-term environmental targets, Sony worked to reduce the consumption of water at its sites in line with its target of achieving an absolute reduction of 30%, compared with the fiscal 2000 level, by fiscal 2015. In fiscal 2015, the last year of Green Management 2015, Sony sites used approximately 12.38 million m3 of water, a decrease of approximately 54% compared with the fiscal 2000 level, despite being up about 17% from the previous fiscal year. The reduction from fiscal 2000 levels was achieved by implementing water conservation and wastewater recycling measures at Sony sites. Water consumption per unit of consolidated net sales was 1.22 m3/million yen in Japan and 0.31 m3/million yen outside Japan.
Under Green Management 2020, which started in April 2016, Sony is working on a new target for fiscal 2020 of reducing absolute water usage at Sony sites by 5% compared to the fiscal 2015 level.
Sony also takes steps to ensure the quality of wastewater at its sites. In addition to observing related laws and regulations in each of the countries and territories in which it operates, Sony manages wastewater quality using stricter criteria than it is required to. For example, the introduction of sophisticated water treatment facilities has enabled it to reduce BOD and COD levels* in wastewater.
