Reducing CO2 Emissions

Introducing corporate efforts to reduce CO2 emissions

CO2 Emissions at the Yamaha Motor Group

The Yamaha Motor Group endeavors to identify greenhouse gas emissions resulting both directly (e.g., from the burning of fuel at factories) and indirectly (e.g., from electricity use at factories and offices) from its corporate activities at each location, 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.

*Greenhouse gas: For Yamaha Motor, this is almost entirely CO2.

Calculating Greenhouse Gas Emissions Along the Supply Chain

The Yamaha Motor Group strives to identify greenhouse gas emissions released directly, such as by burning fuel at factories in the course of manufacturing operations (Scope 1), indirectly through the use of electricity in factories and offices (Scope 2) and other emissions (Scope 3), to reduce those amounts.

Boundary Scopes 1 and 2: 115 companies*, comprising Yamaha Motor Co., Ltd. and manufacturing and non-manufacturing consolidated subsidiaries or affiliated companies

*As a result of reviewing the environmental consolidation scope from the 2018 data, most of the non-consolidated subsidiaries have been excluded from the boundary.

Reducing CO2 Emissions at the Manufacturing Stage

Though Yamaha Motor’s initial target for fiscal 2018 was a 9% reduction in CO2 emissions per net sales compared with fiscal 2009, the Company was able to reduce those emissions by 36%, thereby achieving the target. However, overall emissions increased 1% year on year.

New energy sources such as solar power and cogeneration accounted for 11 thousand MWh (7% of total electric power consumption). 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 in 2018, solar power generation systems were introduced in locations including the United States, Thailand, and Taiwan.

The amount of power generated in 2018 totaled 12,878 MWh (equivalent to a reduction of roughly 11,801 t-CO2), and was used for various factory operations and office lighting and air conditioning.

Taking Our Know-How Accumulated in Japan Worldwide

In 2018, 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 (Theoretical-Value-Based energy project) 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 automated shutdown of electrical machinery when not needed, CO2 controls for exhaust fans, a shift to hydraulic servomotors, and the reduction of boiler blow rates. These led to the lowering of CO2 emissions per net sales (39% below the 2012 level, the year prior to the start of the project) and reductions in CO2 emissions (15% below the 2012 level).

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.

In 2018, distribution-related CO2 emissions per unit of sales were reduced by 0.4%, owing to efforts including improving the load factor, consolidated transportation, and increasing transportation efficiency.

We will continue working to improve transportation efficiency going forward.

Products that Address Climate Change

Countermeasures against the effects of global warming are one of the most important ways to address climate change, including both reducing the effects of climate change and preparing for the risks associated with climate change. The Yamaha Motor Group is addressing climate change through its wide-ranging business activities and is also creating products that address climate change.

Next-generation, high-performance compact engine: BLUE CORE

Yamaha Motor developed the BLUE CORE high-performance compact engine as a higher-dimension embodiment of both the joy of riding, with an emphasis on fuel efficiency and environmental performance. The engine was first included in the Nozza Grande, a scooter targeting women that was released in Vietnam in 2014. BLUE CORE is an environmentally-friendly platform engine that makes further advances in highly efficient combustion, higher cooling performance, and power loss reduction, with high-dimension tuning in line with the model’s special features also possible. We are currently developing a range of variations of this technology, which is particularly popular in the ASEAN region and delivers vastly superior environmental performance compared with previous engines.

Clean Water Supply System provides reliably safe water

Increased flooding caused by climate change is leading to higher pollution of water resources. Drinking contaminated water harms the health of the people in a community, impeding social and economic development. The Yamaha Clean Water Supply System uses natural sand, gravel, and the photosynthesis of algae in a “slow sand filtration” system to purify water, providing a safe, stable supply of potable water to areas where it is difficult to obtain.

Addressing flooded roads resulting from climate change

Increased rainfall caused by climate change significantly impairs the driving performance of cars and motorcycles, especially in the ASEAN region where infrastructure is weak. Yamaha Motor is addressing flooded roads by introducing motorcycles with the air cleaner placed at a higher position than in ordinary models.

Energy Consumption within Yamaha Motor Group

In FY2018, the Yamaha Motor Group’s total energy consumption was 9.51 million GJExternal Assurance, of which electricity accounted for 72%, or 6.86 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.
