Reducing CO2 Emissions

Introducing corporate efforts to reduce CO2 emissions

CO2 Emissions at the Yamaha Motor Group

As a manufacturer of motorcycles and other transportation machinery, the Yamaha Motor Group considers the reduction of greenhouse gas emissions to be the most critical environmental issue facing the world today.

We are targeting an annual 1% reduction in CO2 emissions per unit of sales as a common goal for the entire Group, and are working to reduce emissions in all of our business activities including product development and manufacturing.

In fiscal 2016, we reduced CO2 emissions by 9,000 t-CO2 from the previous year, to 548,000 t-CO2. Though CO2 emissions per unit of sales increased by 7% as a result of lower sales from foreign exchange effects, they have been reduced by 29% compared with 2012, the benchmark year for our global utility cost reduction activities. Going forward, we will continue working to reduce greenhouse gases through ongoing monitoring and activities aimed at lowering energy usage at Group companies in Japan and overseas.

Reducing CO2 Emissions and CO2 Emissions per Unit of Sales at the Manufacturing Stage

Though Yamaha Motor’s initial target for fiscal 2016 was a 7% reduction in CO2 emissions per unit of sales compared with fiscal 2009, the Company was able to reduce emissions by 23%, thereby achieving the target. The year-on-year reduction in CO2 emissions per unit of sales was 5%.

In addition, new energy sources such as solar power and natural gas cogeneration accounted for 12 thousand MWh (6% of total electric power consumption), resulting in a 3.9 thousand t-CO2 reduction (thermal power generation conversion). We are committed to continuing the introduction of energy-saving devices and improving our operational management system.

Renewable Energy Usage at the Yamaha Motor Group
Power Generation System Using Solar and Wind Power at Factories

The Yamaha Motor Group is installing power generation systems that use solar and wind power. Following the installation of a solar power generation system at the Iwata Main Factory in 2004, these systems have been successively installed elsewhere and the use of renewable energy is expanding.

Installations continue at overseas locations as well, and during 2016, a 4,000 kw solar power generation system began operating in India along with a 150 kw system in the United States.

The amount of power generated in 2016 totaled 4,210 MWh (equivalent to a reduction of roughly 2,095 t-CO2), and was used for various factory operations and office lighting and air conditioning.

Solar power - 60 kw (Fukuroi Factory, Japan)
Wind power - 1 kw  (Nakaze Factory, Japan)
Solar power – 4,000 kw (IYM-SJP, India)
Solar power – 150 kw (YMMC, United States)
Taking Our Know-How Accumulated in Japan Worldwide

In 2016, the Yamaha Motor Group continued to pursue activities aimed at further reducing CO2 emissions. The main initiative has been the rollout of the Global Utility Cost Reduction Project (GUTS) since 2013, for energy conservation at Group companies in Japan and overseas.

This project builds on the energy conservation expertise accumulated in Japan by sharing this know-how with overseas Group companies and working together to reduce CO2 emissions across the Group.

Initiatives during the year included the lowering of compressor operating loss, reduction of air leakage, stoppage in operation of machinery when not needed, automated shutdown of auxiliary processing equipment, and application of heat-blocking coating of furnaces. These led to lower CO2 emissions per unit of sales (29% below the 2012 level, the year prior to start of the project) and reductions in CO2 emissions (12% below 2012).

Since launching this project, Yamaha Motor’s energy efficiency technicians have visited a total of 30 locations in 13 countries, in which Yamaha Motor Group companies operate, including those in Japan, and the project has been expanded to cover 98% of Groupwide CO2 emissions with the aim of reducing energy loss.

Going forward, we will continue pursuing activities aimed at further reducing emission volumes at each factory and office in order to lower overall CO2 emissions.

Reducing CO2 Emissions at the Distribution Stage

Yamaha Motor has established the goal of "improving transportation efficiency by 1% a year (compared with 2006)" for all divisions. Yamaha Motor’s basic approach is to implement measures beginning with those that will have the greatest CO2-limiting impact while balancing the energy conservation benefit with cost benefit. Yamaha Motor has also established a working group that centrally promotes CO2 emission reductions in distribution.

Distribution has improved with the realignment of the manufacturing layout completed in 2016, reducing the transportation of goods in terms of both volume and distance, and thereby lowering total distribution-related CO2 emissions by 2.1%.

At the same time, with an increase in goods such as pleasure-use boats with low transportation efficiency (a low load factor), CO2 emissions per unit of sales increased 2.4%.

We will continue working to improve transportation efficiency going forward.

Yamaha Motor Launches GDR155 Scooter ASEAN Strategic Model

Yamaha Motor launched the GDR155, a new scooter blending a stylish form and sporty ride, which has been developed as a strategic model for ASEAN markets. The introduction of the new model aims to create in the ASEAN region a sporty scooter category, which will become a stepping stone to the big scooter class. Launched in Vietnam as the NVX and in Thailand as the AEROX in December 2016, the GDR155 will subsequently be introduced in Indonesia and other ASEAN markets.

Development of the GDR155 targeted upwardly-mobile 25 to 30-year-old males with the intention of being crowned the “ASEAN Best Sporty Scooter.” BLUE CORE engine incorporates a Smart Motor Generator—a Yamaha first—which combines startup with power generation functionality to deliver quieter starting while also reducing power generation loss.

The main features of the GDR155 include 1) a 155cc liquid-cooled BLUE CORE engine (with VVA*1) providing superior acceleration and fuel efficiency, 2) a lightweight 116kg body for sporty handling, and 3) a new design exuding both high maneuverability and a luxury feel. In addition to the standard model GDR155, the R version, featuring rear suspension with sub-tank and wave-shaped front disks, and the A Version, with Stop & Start System*2, Smart Key, and ABS, are also available*3.

The GDR155 will be manufactured in plants in Vietnam, Thailand, and Indonesia, and a rich variety of color and graphic variations suited to the tastes of customers in each country will be offered.

Yamaha Motor Group CO2 Emissions Data

In fiscal 2016, the Yamaha Motor Group’s total energy consumption was 10.13 million GJ, of which electricity accounted for 74%, or 7.50 million GJ. Around 80% of the Group’s energy consumption was in Asia, including Japan. Seeking to reduce energy consumption, we are working in a deliberate manner on various initiatives. These include installation of melting furnace air-ratio control systems, introduction of thermal insulation in heat treatment furnaces, installation of power-saving equipment in factories, improvement of operational efficiency of compressors, and reduction of air usage.
