Our Commitment to Carbon Neutrality Reducing Environmental Impact in the Foundry Industry
In the casting industry—known for its high CO₂ emissions—we are actively working to minimize environmental impact by strengthening our efforts toward achieving carbon neutrality.
A major portion of emissions in the casting process—approximately 70% of our total CO₂ output—comes from the use of coke as fuel.
To reduce this, we are proactively introducing new technologies to replace conventional energy sources and improve environmental performance across our operations.
Our CO₂ Emissions Ratio
Target
To support our journey toward carbon neutrality, Yoshiwa Kogyo has set the following medium- and long-term goals.
Reduce CO₂ emissions by 50% by 2030,
compared to fiscal year 2013 levels
Achieve full carbon neutrality by 2050
Key Initiatives
Introduction of Biofuels
To reduce our reliance on coke, we are transitioning to biofuels in our manufacturing processes. Biofuels are a sustainable energy source that is more environmentally friendly and emit fewer greenhouse gases. We see them as a promising solution for reducing environmental impact in the casting industry.

Improving Energy Efficiency
We aim to enhance energy efficiency across all stages of production. This includes boosting productivity, visualizing energy loss through integrated management of equipment operation data and energy consumption, and introducing energy-saving technologies. These efforts help us reduce fuel usage while maintaining—and even improving—the productivity of our casting processes.

Use of Renewable Energy
We are actively adopting renewable energy sources, such as solar power, to meet the energy needs of our plants and offices. By supplementing our electricity consumption with clean energy, we further reduce our environmental footprint.

Collaboration with Stakeholders
Achieving carbon neutrality requires more than just our own efforts—it calls for close collaboration with all stakeholders. We are committed to building a sustainable, environmentally conscious business model by working together with our suppliers, employees, local communities, and customers.
