Yamaha Motor Integrated Report 2022

As we strive to be a Kando Creating Company through our businesses, we believe carbon neutrality initiatives present new opportunities for growth, and by combining them with production processes that eliminate waste, we are working to both further improve productivity and reduce the environmental impact of our production sites. Additionally, utiliz-ing technology to enhance the efficiency of theoretical-value-based production is how we connect manufacturing and production to the pursuit of customer value. Garnering Affinity via Carbon-Zero Plants and New Growth Opportunities 56Initiatives for Carbon-Neutral MonozukuriTo aid in creating a decarbonized society, we are promoting initiatives to minimize energy consumption and are switching to renewable energy sources to make Yamaha Motor factories carbon-neutral. The minimization of energy consumption hinges on our theoretical-value-based energy approach and innovations to pro-duction processes. Under the theoretical-value-based energy con-cept, we aim to apply a theoretical value to the energy used in all processes. This method treats only energy that is truly essential as having “value” and allows us to bridge the gap between this ideal and our current situation. The focus on the ultimate achievement of the theoretical targets with this method differentiates it from the previous loss-reduction approach. Through this initiative, we will achieve the highest level of energy conservation to date. Furthermore, to bring innovations to our production processes, we aim to achieve significant energy conservation in line with the timing of equipment updates and replacements. The introduction of a new aluminum die-casting machine last year resulted in a 44% decrease in energy consumption compared with previous models thanks to new advances, such as a heat recovery system, better thermal insulation, electrification of hydraulics, and lower cycle times. Other new technologies being considered for the future of the casting process include ultra-high thermal insulation, emissions-free inorganic cores, and high-speed low-pressure die casting.Initiatives for RecyclingAs general policy for mitigating climate change, the reduction of CO2 emissions in corporate activities has become an important societal issue. Since the Japanese government announced its goal of achieving carbon neutrality by 2050, there has been increasing concern and effort by companies regarding initiatives for decarbonization. has been a shift toward a circular economy, particularly in areas such as the European Union. In a circular economy, services are designed under the premise of resource recovery and reuse, with the aim of creating a society with no waste. Amid such an external environment, the Company has been engaging in reducing the waste from Group plants from the per-spective of carbon neutrality and a circular economy. We have been able to manufacture engine components and exterior parts made from recycled materials by working to expand the range of recycled materials used when developing products. Additionally, we made enhancing the quality of recycling, namely increasing the number of recycled raw materials, and achieving zero In conjunction with the achievement of carbon neutrality, there Meanwhile, switching to cleaner energy relies on the utilization of renewable energy sources and electrification. During the three-year duration of the new Medium-Term Management Plan, we will increase the use ratio of renewable energy by 2.5 times by accelerating the introduction of solar energy power generation. Additionally, we will shift to using CO2 emission-free energy gener-ated by hydroelectric powerplants at key domestic business sites within 2022, and this is expected to reduce domestic CO2 emissions by 70%. Under electrification, we are making progress with switch-ing from fossil-fuel based energy to electricity, such as vaporless air conditioning and the complete electrification of equipment. We will move forward viewing carbon neutrality initiatives as new opportunities for growth with the hope that they lead to the creation of new value, including the creation of a highly productive and comfortable work environment, the achievement of carbon neutrality for our business partners, and the garnering of widespread affinity for the Yamaha brand.landfill waste by increasing the recycling rate new global targets for achieving carbon neutrality. We are planning to create a raw mate-rial recycling system with the aim of recycling all waste. Different approaches to purchasing raw materials are being considered for different materials. While the majority of the ingots used for aluminum casting—a Yamaha Motor field of expertise—already contain recycled materials as of the end of 2021, we are further promoting this switch with the aim of achieving 100% recycled materials. We are undertaking thermal recycling by chang-ing the materials that make up the FRP used in boat hulls and other products. For other resin materials, we are developing recycled materials that do not include substances hazard-ous to the environment.Solar power generation at Chennai Plant (India)Recycled resinManufacturing and Production (Monozukuri)
