In response to the growing sense of crisis about global warming around the world, the Japanese government and relevant industries are stepping up efforts to realize a decarbonized society. The Rinnai Group, which handles household appliances that mainly use fossil fuels, has also set targets for 2030 and adopted a corporate policy to realize a decarbonized society by 2050.
In the life cycle of Rinnai products, CO2 emissions from product use account for an overwhelmingly large proportion. Accordingly, we recognize our responsibility to improve the environmental performance of the products we sell and promote the popularization of our environmentally friendly products. The table below shows our targets for CO2 emissions from our business activities (product development, manufacture, and sale/distribution) and product use (usage and disposal) in the life cycle.

Initiatives and Direction to Realize Low-Carbon and Decarbonized Society

To reach our “low-carbon targets” for 2030, we will accelerate the spread and expansion of high-efficiency Eco-Jozu water heaters and ECO ONE hybrid water heaters with heating systems, which we have been actively promoting. To this end, we will increase sales of ECO ONE, which reduces CO2 emissions by around 50% compared with conventional water heaters, to 300,000 units per year by 2030. To reach our “decarbonization” target for 2050, we will closely monitor the development of technologies, such as methanation and propanation, and explore the potential for continued use of conventional equipment. At the same time, we will pursue a long-term business strategy by developing systems that combine hydrogen combustion equipment and hybrid water heaters with renewable energy technologies.
