Third-party verification
In order to ensure the reliability of reporting, in fiscal 2011 Casio began requesting third-party verification of its environmental data. K.K. Satisfactory International was contracted to do the auditing, which covered environmental performance, material balance, and site-specific data. Onsite audits were also conducted at the Casio Computer Co., Ltd. headquarters, Hamura R&D Center, Hachioji R&D Center, Casio Electronic Manufacturing, and Casio Micronics.

Environmental Performance
CO2
Reducing CO2 emissions
Fiscal 2011 marked the third year of the target period (five years from fiscal 2009 to fiscal 2013) for CO2 emissions from sites in Japan. The performance figures using comparisons with the base year are average values for the initial year (fiscal 2009) through the third year (fiscal 2011).
The target for production sites in Japan was a 35% reduction in CO2 emissions per unit of actual production compared to fiscal 1991. In fiscal 2011, the sites’ CO2 emissions were approximately 41% lower than in fiscal 1991, which also represented a roughly 12% decrease from the previous fiscal year. The main reason for this decline from the previous year was the transfer of the TFT-LCD and cellular phone businesses, and their removal from the consolidation scope of the Casio Group.
The target for office sites in Japan was a 9% reduction in the total amount of CO2 emissions compared to fiscal 1991. In fiscal 2011, emissions were about 26% lower than in fiscal 1991, meeting the target again this year. This was also an approximately 11% reduction from the previous fiscal year.
Fiscal 2013 is the target year for all sites outside Japan. The target for production sites outside Japan was a 30% reduction in CO2 emissions per unit of production compared to fiscal 2005. Fiscal 2011 emissions for these sites were about 12% lower than in fiscal 2005, an approximately 22% reduction from the previous year.
The target for office sites outside Japan was a 3% reduction in the total amount of CO2 emissions compared to fiscal 2005. In fiscal 2011, emissions were approximately 47% higher than in fiscal 2005, which also represented an approximately 2% increase over the previous fiscal year.
Casio will continue to strive to improve the energy efficiency of its production equipment and to streamline production processes at all of its production sites in and outside Japan. Casio will also work to reduce CO2 emissions by implementing energy-saving measures for its lighting and heating/cooling equipment at offices in and outside Japan.

SF6 gas
Reducing SF6 emissions
Casio has set a target of reducing its emissions of greenhouse gases other than CO2 to less than year 2000 levels by 2010.* The fiscal 2011 results for SF6 emissions were approximately 59% lower than in 2000, and this represented an approximately 74% reduction compared to the previous year. In April 2010, the TFT-LCD business (Kochi Casio and the electronic component division of the Hachioji R&D Center) was transferred, and removed from the consolidation scope of the Casio Group. This was the main reason for the emissions reduction.
In the future, Casio will put effort into reducing greenhouse gases including those contained in dust blowers, spot freezing and sprays used mainly at service sites.
* This target is set on a calendar year basis, while other overall results are on a fiscal year basis.

Waste
Reducing waste
Casio evaluates its waste reduction (waste and valuables) using fiscal 2013 as the target year.
The target for reducing waste produced from sites in Japan was a 50% reduction in waste per unit of actual production compared to fiscal 2001. In fiscal 2011, waste was reduced by about 43% compared to fiscal 2001, which also represented an approximately 30% reduction from the previous year. Although the amount of waste produced compared to the previous fiscal year fell by about 15%, this was due to the transfer of the TFT-LCD and cellular phone businesses, and their removal from the consolidation scope of the Casio Group.
The target for reducing waste from production sites outside Japan was a 30% reduction per unit of production compared to fiscal 2005. In fiscal 2011, emissions were reduced by about 31% compared to fiscal 2004, for an approximately 22% reduction from the previous year. Further waste reduction measures for production sites outside Japan are being considered.

Water resources
Reducing Usage of Water Resources
Water resource input is evaluated using fiscal 2013 as the target year.
The target for production sites in Japan was a 25% reduction in water resource input per unit of actual production compared to fiscal 2001. In fiscal 2011, water input per unit of actual production was about 42% lower than in fiscal 2001, which also represented a reduction of about 49% from the previous fiscal year. Total water resource input was down by about 21% from the previous year. This was due to the transfer of the TFT-LCD and cellular phone businesses, and their removal from the consolidation scope of the Casio Group.
The target for production sites outside Japan was a 15% reduction in water resource input per unit of production compared to fiscal 2005. In fiscal 2011, the figure was 15% higher than in fiscal 2005, representing an approximately 40% increase compared to the previous year. This increase was due to the rise in TFT production output at the Casio Computer (Hong Kong) Ltd. Casio will continue to strive to reduce water usage.

Paper
Reducing usage of paper resources
The reduction target for the usage of office paper at sites in Japan, set in fiscal 2010, was a 10% reduction compared to fiscal 2008 by fiscal 2013, per unit of sales. The result for fiscal 2011 was about 33% higher than in fiscal 2008. This increase was due to a drop in sales, as the total volume of office paper used fell from 115 tons in 2007 to 75.5 tons in 2010. Along with the increased promotion of green IT, Casio will reinforce its efforts to reduce paper usage.

PRTR
Reducing PRTR substances
The target for reduction of emissions of substances specified by Japan's PRTR Act was a 40% reduction per unit of actual production compared to fiscal 2004, by fiscal 2013. In fiscal 2011, Casio met the target for another consecutive year, with approximately 71% lower emissions than in fiscal 2004, which was a reduction of 36% over the previous year. Casio will continue striving to further reduce the use of these chemicals.

VOC, NOx, SOx, dust
Reducing VOCs
Fiscal 2011 is the target fiscal year for reducing atmospheric emissions of volatile organic compounds (VOCs) from production sites in Japan. The target was a reduction of 30% compared to fiscal 2001. In fiscal 2011, Casio's emissions of VOCs were about 55% lower than in fiscal 2001, achieving the target. This also represented a reduction of approximately 34% from the previous fiscal year. Casio will continue to pursue VOC replacements.

Reducing Nox,SOx,Dust
Casio's atmospheric emissions of nitrogen oxides (NOx), sulfur oxides (SOx) and dust in the peak year of fiscal 2006 were 138 tons, 37 tons, and 2 tons, respectively. Emissions in fiscal 2011 were 1.9 tons, 1.1 tons, and 0.2 tons, respectively. These dramatic reductions are attributed to the transfer of the TFT-LCD and cellular phone businesses, and their removal from the consolidation scope of the Casio Group.
By adjusting settings and practicing indoor temperature management, Casio also intends to reduce emissions of atmospheric pollution generated by air conditioning equipment such as hot and chilled water generators).
