Yamaha's High-Cycle SMC cuts outboard motor molding time by 20%, lowering CO2 emissions in production

Yamaha Motor and Japan Composite co-developed High-Cycle SMC, a paintable sheet molding compound that reduces molding cycle time by 20% compared to conventional materials. The material requires less thermal energy during the molding process, which is projected to lower CO2 emissions by 20% as well. Since 2025, it has been used for the powerhead cowling of Yamaha outboard motors, improving production efficiency and cutting Scope 1 and Scope 2 emissions. This is part of Yamaha's Environmental Plan 2050, aiming for carbon neutrality across its supply chain by 2050, with a faster 2035 target for its own manufacturing sites. The reduction in energy use during molding directly supports these goals. The material was verified and optimized by Yamaha Motor, Yamaha Marine, and Japan Composite, showing how industrial process tweaks can deliver measurable decarbonization gains. The news is relevant for anyone tracking industrial efficiency, composite materials, or manufacturing emissions. It demonstrates a concrete step in reducing the carbon footprint of production, not just through offsets but by changing the process itself.
