CO2 Emissions (from energy consumption)
CO2 emissions of the Yamaha Group in Japan declined by 1,000 tons of CO2 compared with the previous fiscal year to 62,700 tons of CO2 in fiscal 2011. This was 42% lower than levels recorded in fiscal 1990. In addition to a host of measures encompassing the integration of headquarters factory grand piano manufacturing processes to the Kakegawa Factory, this result is largely attributable to the drop in production volume due mainly to the sale of certain businesses and deterioration in the economic environment.
In addition, CO2 emissions per unit of sales were 23.7 tons of CO2 per ¥100 million, an increase of 2.7% compared with the previous fiscal year.
CO2 Emissions (from energy consumption)
Non-CO2 Greenhouse Gas Emissions*1
Emissions of greenhouse gases other than CO2 were 6,900 tons in fiscal 2011, a 600 ton reduction compared with the previous fiscal year. The major factors behind this reduction were the decrease in production, introduction of processing equipment, and changes in processing methods*1.

Non- CO2 Greenhouse Gas Emissions
Breakdown of Energy Consumption
Energy use in fiscal 2011 fell 17 TJ* compared with the previous fiscal year to 761TJ.
Electricity and gas (city gas, LPG, LNG) accounts for 88% of the total.
- * Energy consumption in the previous fiscal year was recalculated and adjusted. This figure represents the difference with the revised value.

Amount of HCFCs Used
By the end of 1993, the Yamaha Group in Japan stopped using specified CFCs in an effort to protect the ozone layer. The Group then worked to reduce the amount of HCFC used as washing agents in metal cleaning processes, eliminating their use completely in fiscal 2005.
NOx (nitrogen oxide) Emissions
NOx is generated by the burning of fuels such as heavy oil, coke, and LPG. In fiscal 2011, Yamaha Group NOx emissions in Japan decreased by 1.2 tons compared with the previous fiscal year to 28.7 tons.
NOx (Nitrogen Oxide) Emissions
SOx(sulfur oxide) Emissions
SOx is generated primarily through the burning of heavy oil, coke, and other fuels. Because the sulfur content of fuel contributes to these emissions, the Yamaha Group in Japan has adopted low-sulfur fuels. In fiscal 2011, emissions fell by 0.1 tons compared with the previous fiscal year to 16.2 tons.

Complying with the PRTR*3 Law
In fiscal 2011, the Yamaha Group handled a total of 310 tons of substances designated under the PRTR Law, a decrease of 4% compared with the previous fiscal year.
Of the 56 tons released into the environment, about 86% comprises styrene, toluene, and xylene from painting processes. Going forward, Yamaha will continue efforts to reduce VOC emissions.

The PRTR Law is an abbreviation of the Law Concerning Reporting, etc. of Releases to the Environment of Specific Chemical Substances and Promoting Improvements in their Management.

VOCs (Volatile Organic Compounds) Atmospheric Emissions
The Yamaha Group is working to reduce the emission of volatile organic compounds (VOCs) released during product coating, adhesion, and other processes. VOCs, which include a wide range of substances such as toluene, xylene, and ethyl acetate, are believed to be the source of air pollutants such as optical oxidants and suspended particulate matter.
In fiscal 2006, the Yamaha Group formed a working group to address VOC emissions reduction, conducted studies of VOC use and emission at each business site and investigated methods for reducing emissions. The Group has set the fiscal 2010 target of a 30% reduction in emissions compared to fiscal 2000 levels. All business sites have been making efforts toward this goal, and have successfully reduced VOC emissions by approximately 70%.
After that, the Group has been continuing the effort and VOC emissions fell by 73% in fiscal 2011.
