Preventing Global Warming
Energy-saving emphasis on products
In Japan, the Act on the Rational Use of Energy—known more informally as the “Energy Efficiency Act”—designates some food service equipment as specific equipment under Top Runner Program Standards*1. Hoshizaki strives to develop high-energy-efficiency products that exceed these standards and bring these products to market ahead of the target fiscal year*2. For example, we launched sales of a showcase with enhanced energy-saving features in 2019, a year ahead of the target fiscal year. Also of note, the display panel indicates that the showcase is operating in energy-saving mode, raising awareness among customers using the showcase and highlighting reduced electricity usage.
HOSHIZAKI AMERICA handles development and sales of environmentally aware, highly energy-efficient products, and has maintained its standing as a Partner of the Year - Product Brand Owner under the ENERGY STAR®*3 program for nine consecutive years since fiscal 2012. The newest accolades recognize the positive environmental impact of the Steelheart series, a line of non-CFC (propane) commercial-use refrigerators that reduces annual greenhouse gas emissions by about 25,000 tons, or 21.0%*4, and the KM Edge X series, a line of energy-saving ice machines that contributes to power consumption savings of about 8.5%*4, or US$1.7 million, a year. Both series debuted in 2019. In addition, HOSHIZAKI AMERICA received the Partner of the Year – Sustained Excellence Award for 2020, marking the sixth time that the company has captured this award. It is the highest level of achievement under the ENERGY STAR® program and given to companies that have earned Partner of the Year recognition for several consecutive years.
In Europe, demand for CFC-free products is growing due to the F-gas (fluorinated greenhouse gas) Regulation*5 that takes effect in 2022. In response, Hoshizaki is developing and marketing non-CFC ice machines using R290, a natural, refrigerant-grade propane. Less R290 is needed to charge a cooling system compared with hydrofluorocarbon-based refrigerants. In addition, R290 reduces the impact on global warming. We developed and launched a non-CFC ice dispenser in 2019, and a crescent-shaped ice machine in 2020. Going forward, we will apply new CFC-free refrigerants to our products and expand the types of machines with enhanced energy-saving features.
*1 Requires manufacturers to develop products exceeding the highest level of energy efficiency achieved by products brought to market at a certain point in time.
*2 Fiscal year in which to achieve *1 criteria set by product and category.
*3 Program run by the U.S. Department of Energy and the U.S. Environmental Protection Agency since 1992. The goal is to raise the energy efficiency of equipment and reduce CO2 emissions. Products that meet specific energy efficiency standards are recognized with ENERGY STAR certification and are allowed to carry the associated mark.

*5 A regulation prohibiting the sale of equipment that uses alternative CFC refrigerants.
CO2 emissions reduction in domestic production processes
Hoshizaki has taken various steps, including the introduction of energy-saving equipment, improvements in operation of equipment, and enhanced operating efficiency, in both manufacturing departments and administrative departments to reduce unit CO2 emissions from energy consumption during business activities. In parallel, we are working to cut the amount of energy used in transport operations by designing products to be more lightweight and comprise fewer components, and we are also vigorously implementing measures to cut power consumption by improving production processes.
Through these efforts, CO2 emissions in fiscal 2019 reached 12,289t-CO2, or 92.0% of the level posted in the previous year.
CO2 emissions reduction overseas
Western Refrigeration Pvt. Ltd., a member of the Hoshizaki Group in India, installed a photovoltaic system with an area of 5,000m2 on the roof of the Sanjan Plant when that facility was constructed. The system has been in constant operation since April 2017 and provides the power for production processes. It generates 500kWp (kilowatt peak), with an estimated CO2 emissions reduction effect equivalent to planting about 29,500 trees.
