CO2 Emissions (from energy consumption)

  CO2 emissions of the Yamaha Group in Japan declined by 1,600 tons of CO2 compared with the previous fiscal year to 61,100 tons of CO2 in fiscal 2012. This was 44% 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 and the integration of wind instrument manufacturing plants in Saitama to the Toyooka 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 23.8 tons of CO2 per ¥100 million, an increase of 0.5% compared with the previous fiscal year.

Non-CO2 Greenhouse Gas Emissions*1

  Emissions of greenhouse gases other than CO2 were 6,900 tons in fiscal 2012, a 300 ton increase compared with the previous fiscal year. The major factor behind this increase was a change in the type of gas consumption owing to a change in production item.

Breakdown of Energy Consumption

  Energy use in fiscal 2012 fell 14 TJ compared with the previous fiscal year to 747TJ.

  Electricity and gas (city gas, LPG, LNG) accounts for 89% of the total.

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 2012, Yamaha Group NOx emissions in Japan were on par with the previous fiscal year at 28.8 tons.

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 2012, emissions fell by 2.1 tons compared with the previous fiscal year to 14.1 tons.

Complying with the PRTR*3 Law

  In fiscal 2012, the Yamaha Group handled a total of 302 tons of substances designated under the PRTR Law, a decrease of 2.6% compared with the previous fiscal year. Emissions released into the environment decreased by 11 tons to 45 tons.

  Of the 45 tons released into the environment, about 85% comprises styrene, toluene and xylene from painting processes. Going forward, Yamaha will continue efforts to reduce VOC emissions.

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 one of the sources 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 implemented initiatives toward the goal of a 30% reduction set the fiscal 2010 target of. All business sites have been making efforts toward a goal of a 30% reduction in emissions compared to fiscal 2000 levels by fiscal 2010 and successfully reduced VOC emissions by approximately 70% in fiscal 2010 relative to fiscal 2000 levels. After that, the Group has been continuing the effort and VOC emissions fell by 74% in fiscal 2012 relative to fiscal 2000 levels.
