*1
Due to an expansion of the boundary
*2
Data collection started from FY2015
*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 consumption 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
VOC: Volatile organic compounds
*7
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
*8
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
*9
Environmental Investment Costs in Japan: Environmental conservation costs relating to capital investment for complying with environmental laws and regulations and reducing environmental impact
