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 and is working on this issue. 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.

Since 2013, we have been implementing global energy conservation activities at all of our manufacturing sites including those overseas, with the aim of achieving a balance between economic and environmental considerations (CO2 emissions reduction). We are also promoting the efficient use of energy by introducing energy conservation expertise accumulated in Japan to Group companies in Japan and overseas.

Activities for Identifying and Reducing Greenhouse Gas Emissions

The Yamaha Motor Group endeavors to identify greenhouse gas emissions resulting both directly (Scope 1, e.g., from the burning of fuel at factories) and indirectly (Scope 2, e.g., from electricity use at factories and offices), as well as other emissions (Scope 3) from its corporate activities at the locations in which it operates, and to reduce those amounts.

We will also work to more precisely measure direct and indirect emissions at each location, and to further reduce emissions at each factory and office.

Reducing CO2 Emissions at the Manufacturing Stage

Though Yamaha Motor’s initial target for fiscal 2017 was an 8% reduction in CO2 emissions per unit of sales compared with fiscal 2009, the Company was able to reduce emissions by 37%, thereby achieving the target. However, CO2 emissions per unit of sales increased 1% year on year due to the introduction of large-scale equipment and other factors.

New energy sources such as solar power and natural gas cogeneration accounted for 13 thousand MWh (5% of total electric power consumption). We are committed to continuing the introduction of energy-saving devices and improving our operational management system.

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 in 2017, the solar power generation system in Delhi, India was increased from 4.0 MW to 6.2 MW.

The amount of power generated in 2017 totaled 8,056 MWh (equivalent to a reduction of roughly 7,302 t-CO2), and was used for various factory operations and office lighting and air conditioning.

Taking Our Know-How Accumulated in Japan Worldwide

In 2017, 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 consolidation of compressor pipes, automated shutdown of electrical machinery when not needed, application of heat-blocking coating of furnaces, a shift to hydraulic servomotors, and introduction of precision air conditioners that recover exhaust heat. These led to lowering of CO2 emissions per unit of sales (37% below the 2012 level, the year prior to the start of the project) and reductions in CO2 emissions (13% 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 Group-wide 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%.

In 2017, distribution-related CO2 emissions per unit of sales were reduced by 9.7% year on year, owing to efforts including improving the load factor, consolidated transportation, and increasing transportation efficiency.

We will continue working to improve transportation efficiency going forward.

Reducing CO2 Emissions in Product Packaging

“Packaging solution for Yamaha outboard motor repair parts” received a WorldStar award at the WorldStar Competition 2017, held by the World Packaging Organization. The award was given for improvements made to increase the stability of the product and to reduce operational and material costs.

Compared with the conventional packing method in which materials were bonded, this packaging simplifies materials by fixing the center of gravity and sharp shape at one point. It also uses paper tubes made of scrap wood as the material to bear the load. This has reduced operational and material costs by 10%, and made it easier to package and dispose of the packaging, while contributing to reduced material weight and lower CO2 emissions.

Yamaha Motor Group CO2 Emissions Data

In 2017, the Yamaha Motor Group’s total energy consumption was 9.88 million GJ, of which electricity accounted for 72%, or 7.15 million GJ. Around 85% of the Group’s energy consumption was in Asia, including Japan. Seeking to reduce our electricity consumption, we are working in a deliberate manner on various initiatives. These include implementation of status analysis and reduction activities through the introduction of equipment that visualizes electricity usage, installation of power-saving equipment in factories, and adoption of LED lighting at offices.
