Measures to Address Global Warming

  As part of its measures to counter global warming, the Yamaha Group has worked to reduce its greenhouse gas emissions through the use of optimal production methods and equipment configuration, improvements to how air conditioning equipment is operated, installation of equipment with high energy efficiency, and extensive energy management, including adjustments to facility operating hours and thermostat settings. The Group has also introduced cogeneration systems and converted to more environmentally friendly fuel sources.

  In December 2003, we set the target of reducing greenhouse gas emissions by 6% of fiscal 1990 levels by fiscal 2010, and we worked Group-wide to achieve this target.

  In fiscal 2010, we reduced CO2 emissions by 41% relative to fiscal 1990 levels and greatly exceeded our target. In fiscal 2012 as well, we reduced emissions by 44% relative to fiscal 1990 levels with a total of 61,100 tons-CO2. In addition to the measures described above, this achievement is attributable to the sale of certain businesses, and a decrease in production due to the worsening economy. We plan to formulate a new target for beyond, while referring to relevant government targets.

  We also aim to continuously reduce CO2 emissions per unit of sales, and target a 1% reduction compared with the previous fiscal year. In fiscal 2012, we failed to achieve our target, reaching 23.8 tons per ¥100 million, an increase of 0.5% year on year, which was partly attributable to s decrease in sales. CO2 equivalent emissions of other greenhouse gases totaled 6,900 tons, an increase of 300 tons from the previous fiscal year.

Energy Conservation Through Integration of Wind Instrument Production Process in Japan

  We implemented a variety of energy conservation activities as we integrated the wind instrument production process at Saitama into Yamaha Corporation's Toyooka Factory. By saving space through the integration of production lines and improving layout and reducing power consumption through renewal of electric annealing furnaces as well as through the consolidation and reduction of dust colectors, we achieved a 7% reduction in electricity consumption.

Energy Conservation Activities at String and Percussion Instrument Factory

  Yamaha Music Craft Corporation's Shinden Factory set up an internal energy conservation promotion committee because if failed to achieve the CO2 emission reduction target in fiscal 2010. In establishing themes for initiatives, the company considered concrete measures following a diagnosis of energy conservation by The Energy Conservation Center, Japan. In fiscal 2011, measures were taken which included ensuring the appropriate pressure for compressors, partitioning work booths, introducing electrical-powered monitors and installing mosquito screens in offices, which resulted in a further 11% reduction in CO2 emissions relative to the target. In fiscal 2012, the company achieved the CO2 emissions target by continuing to conserve energy through appropriate management of air conditioning and process integration.

Energy Conservation Activities at a Factory in China

  Hangzhou Yamaha Musical Instruments Co., Ltd. has taken various steps to suppress growing energy consumption resulting from an increase in production.

  In fiscal 2011, the factory reduced energy consumption by 15% per unit of sales on a year-on-year basis. This result can be attributed to improvements made to achieve a 5% reduction target that included a 3% reduction through technological enhancements and a 2% reduction by enhancing the level of management in daily operations. The factory passed a Cleaner Production Audit at the end of 2011 from Hangzhou City officials pursuant to China's Cleaner Production Promotion Law due to these initiatives to conserve energy as well as efforts to reduce waste and strengthen environmental risk responsiveness. In addition, the factory worked on the acquisition of ISO 14001 certification and received approval in May 2012 following a review by outside authorities in April. In fiscal 2012, the factory reduced energy consumption by 8% per unit of sales by conserving energy through such means as formulating and complying with standards for appropriate operation and management of dust collectors, which make up 25% of electricity consumption.

(Examples of Energy-Saving Measures)

(1) Improved equipment
Introduced automated control equipment for compressors (resulted in realization of unmanned control and a reduction in idle time, etc.)
Equalized steam pipe pressure balance for presses (resulted in an improvement in energy efficiency)
Introduced energy-saving equipment when building new facilities and when replacing machinery
(2) Strengthened equipment maintenance
Reduced air and steam leaks through timely maintenance
(3) Improved electricity contracting practices
Switched to contract details in line with forecast consumption per month (resulted in energy savings by implementing consumption forecasts and ensuring awareness of limits)
(4) Enhanced awareness toward energy conservation at workplaces through energy-conservation patrols

Cleaner Production Audit
Cleaner Production Audit

*1 Cleaner Production Audit
China's Cleaner Production Promotion Law was enacted in China in 2003 with the aim of preventing environmental pollution through the realization of clean product manufacturing using clean energy, raw materials and production technology. The key feature of this law is the objective of preventing pollution before it happens rather than taking care of it afterward such as by regulating emissions, which is the traditional approach.
Cleaner Production Audit is granted by a government agency in each region to companies recognized as promoting clean manufacturing as defined in the Cleaner Production Promotion Law, improving resource usage efficiency, reducing and preventing pollutant emissions, protecting the environment, safeguarding people's health and promoting societal development, with the aim of reducing environmental impact in the manufacturing industry.

Reducing CO2 Emissions in Logistics

The Yamaha Group is actively working to increase energy efficiency and reduce CO2 emissions in logistics operations. Guided by a basic policy of raising transport efficiency, we continually review transport routes, adopt routes that incorporate more efficient modes of transport, raise container loading ratios, streamline loading sites and warehouse facilities, and conduct joint transport with other companies. Efforts are also being made to reduce CO2 emissions by disposing of waste locally and switching from air to sea for international shipping.

The Yamaha Group's total domestic transport volume and CO2 emissions in fiscal 2012 decreased 6.2% compared with the previous fiscal year to 18.15 million ton- kilometers1 while CO2 emissions also decreased 7.5% to 2,861 tons.

Reducing CO2 emissions from logistics requires the cooperation of transport companies, so we are working with them to develop appropriate systems. Specific measures include requesting participation in environmental efforts at meetings with the companies and incorporating environmental matters into questionnaires.

Reduced Resources and CO2 Emissions in Piano Frame Transportation

Previously, Yamaha used disposable iron packing racks when transporting piano frames from Japan to Hangzhou Yamaha Musical Instruments Co., Ltd. To eliminate this waste, we introduced returnable packing racks and created a management system that can be used multiple times, and shifted to returnable packing racks for all piano frames bound for China in October 2011.

At the same time, we shortened the transport route. These efforts resulted in a 60-ton reduction in CO2 emissions associated with the disposal of iron packing and a 1,050-ton reduction in iron resource costs for the year. In fiscal 2012, improvements were made such as increasing the number of packs per rack. Further, packing racks for grand pianos were developed and a shift was made to returnable packing racks for all grand pianos bound for Indonesia in May 2013.

Going forward, we will examine the possibility of shortening transport distance and reducing disposable packing materials, including for parts aside from piano frames.
