*1
Due to an expansion of the boundary
*2
Until FY 2018, FY 2005 was used as the base year, but in FY 2019, the base year was changed to FY 2010 in accordance with Hitachi Environmental Innovation 2050.
*3
Figures from FY 2017 include hazardous waste generated from manufacturing sites only. Figures up to FY2016 include waste generated from manufacturing and non-manufacturing sites
*4
From FY2017, for water withdrawals at sales bases where water consumption is not measurable, water consumption is estimated based on the calculation of sales bases where water consumption is measurable and the number of employees.
*5
Due to an increase in the number of sites and that of sales offices that measure the actual amount of water, rather than relying on estimations
*6
Figures for FY2016 and FY2017 have been revised from 4.2 and 3.8, respectively, as a result of correcting erroneous data for some sites
*7
Environmental Conservation Costs in Japan, and Environmental Conservation Effects in Japan (Economic Effects): Amount invested in, and costs arising in relation to, prevention, minimization, and avoidance of environmental impact, clean-up, recovery after accidents, and initiatives that contribute to such, as well as economic effects of such
