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