Based on the AGC Environmental Accounting Calculation Manual created in line with the Environmental Accounting Guidelines 2005 (Ministry of the Environment), Asahi Glass calculates its environmental accounting data to quantify managerial resources spent in reducing environmental impacts and resultant effects.
In fiscal 2010, both our environmental investment amount and environmental cost increased compared with the last year. In particular, the R&D cost substantially increased. This is partly because of the continuous investment in R&D on environmentally friendly products Delivering Technology Solutions for Climate Change, as upheld in our management policy Grow Beyond, and also due to the accelerated development of eco-friendly production technologies.

Scope of data: Asahi Glass (unconsolidated) Target period: January 1 to December 31, 2010

* The breakdown figures do not always add up to the total because of rounding.

Breakdown of Environmental Investment	Breakdown of Environmental Cost

* Environmental remediation costs are excluded from the above summation because the method of allocating cost and investment differs depending on the year of calculation.
* The breakdown figures do not amount to 100% due to rounding.

Environmental Conservation Benefits

Change in environmental impact = (Fiscal 2010 output volume) - (Fiscal 2009 output volume)
Asahi Glass (unconsolidated) Y-to-Y sales ratio = (Fiscal 2010 sales)/(Fiscal 2009 sales) = 6,385/5,278 = 1.210
Sales-corrected change = Simple Y-to-Y change/Y-to-Y sales ratio
*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 fiscal year's level.
