Environmental Impact/Environmental Accounting

The AGC Environmental Indicator to Determine Environmental Impact

The AGC Group formulated the AGC Environmental Indicator in 2006 to independently assess the environmental impact of its manufacturing activities (details shown below). By using this indicator, the Group can calculate how much the environment is affected in relation to improvements in its economic performance while making further improvements.

  • (Note) For detailed environmental performance data, please refer to the Environment section on the Web site and the “CSR Information Supplement.”
  • (Note 1) PJ (peta joule) = 1015J (joule)
  • (Note 2) Total emissions of substances regulated by the PRTR Act (in 2014)

Environmental Accounting

Based on the AGC Environmental Accounting Calculation Manual created in line with the Environmental Accounting Guidelines 2005 (Ministry of the Environment), the AGC Group calculates its environmental accounting data to quantify managerial resources spent in reducing environmental impact and resultant effects. In 2014, the scope of calculations was expanded to include the entire Group.

Environmental Conservation Cost (AGC Group)

(Millions of yen)

  Investment Cost
2014 10,020 45,590
2015 15,854 41,529

(Note) Some data used in the environmental conservation cost calculation process, is estimated based on actual performance data from AGC Asahi Glass.

Environmental Conservation Benefits (Note 1)

  Change in environmental impact (Note 2) Simple Y-to-Y change Sales-corrected change (Note 3)
Total energy consumption -11PJ -7% -7%
CO2 emissions -650,000t -7% -7%
Greenhouse gas emissions -630,000CO2 -6% -6%
Waste sent to landfill 0t 0% 0%
COD emissions 380t 16% 16%
SOx emissions 510t 6% 6%
NOx emissions -3,000t -11% -12%
Soot and dust emissions 328t 53% 54%
  • (Note 1) Change in environmental impact and simple Y-to-Y change: A positive figure indicates an increase and a negative figure indicates a decrease in environmental impact from the previous year’s level.
  • (Note 2) Change in environmental impact = (2015 output volume) - (2014 output volume)
  • (Note 3) Sales-corrected change = Simple Y-to-Y change/Y-to-Y sales ratio
    AGC Group Y-to-Y sales ratio = (2015 sales)/(2014 sales)
    =13,263/13,483=0.98
