We, as an “Eco First Company,” have built an environment management system, in keeping with the slogan of “a clean earth for future generations.” Based on our specific plans, such as to reduce the environmental burden created by our company and its products, the Noritz Group is actively working at activities for global environmental conservation.

Responsibility for Environmental Conservation

Noritz’s consumption of energy for its business operations and by our manufactured products in Japan result in emission of 19.14 million tons of CO2 per year. This represents about 1.4% of the overall CO2 emissions in the nation, which is approximately 1,321 million tons.

CO2 emission calculation for the entire supply chain

Noritz estimated the CO2 emissions of its entire supply chain, using calculations based on the Greenhouse Gas Protocol (GHG Protocol), an international accounting tool, and the General Guidelines on Supply Chain GHG Emission Accounting, produced by the Ministry of the Environment (see table below).
Of the 19.14 million tons representing about 1.4% of the overall CO2 emissions in Japan, which is approximately 1,321 million tons*1, about 97% was generated by consumer use of our products. This makes us realize that the important issues toward COemission reduction is to promote replacement into eco-friendly products and raise the sales share of those products.


As a manufacturer of devices that produce hot water used every day by approximately 20 million households across Japan, Noritz has introduced its "Eco-First Commitment" initiative.

On March 9, 2009, Noritz became the first manufacturer of gas and kerosene appliances to be certified as an "Eco-First Company." We have made a commitment to society that we will advance various initiatives to protect the environment.
Established in April 2008, Eco-First is a system in which companies make a commitment to the Minister of the Environment to advance initiatives to protect the environment. The system aims to further boost environmental conservation efforts by the leading firms in each industry.

Environmental Philosophy and Basic Environmental Policy

We are building an environmental management system based on our slogan of "A Clean Earth for Future Generations," and through specific plans to achieve goals such as environmental impact reduction, the entire Noritz Group is actively working to protect the global environment.

Environmental Philosophy

As a responsible corporate citizen, we aim to achieve a recycling-oriented society, and actively work to protect the global environment in all of our business activities.


A Clean Earth for Future Generations

Basic Environmental Policy

Building an environmental management system
We fulfill our social responsibility by building an environmental management system, and striving for continuous improvement.

Reduction of environmental impact of products and business activities
In our products and business activities, we will contribute to the realization of a recycling-oriented society by reducing environmental impact—through environmental awareness and efforts such as prevention of global warming, conservation of resources, reduction of hazardous materials and wastes, and preservation of biodiversity.

Reduction of environmental risk
Naturally, we comply with environmental laws and regulations, but beyond that we also establish voluntary standards based on an acute awareness of our corporate responsibility to society, and work hard to reduce environmental risk and prevent pollution.

Promoting environmental protection activities through environmental communication
We strive to improve environmental awareness among our employees through environmental education, and we recognize the increasing severity of environmental problems. Therefore, we will act as a responsible corporate citizen to protect the environment, both locally and globally.

Initiatives to Reduce Use of Hazardous Materials

As a voluntary initiative, we have developed hazardous material free products and promoted their sales. These products now represent 65.3% of total sales.
In light of a revised directive on Restriction on Hazardous Substances (RoHS) in 2019, we are now working on disclosing the content ratio of chemical substances in our products.

Reduction of Product Environmental Impact and the Supply Chain

Efforts to reduce substances with environmental impact in products
At the Noritz Group, we are working to strengthen our green supply chain by developing a chemical substance management system, disclosing information, and auditing chemical substances. To reduce hazardous substances in products, we carry out chemical substance management based on the Noritz Group Guidelines for Management of Substances with Environmental Impact,*1 and by developing products compliant with hazardous substance standards (GP-compliant products),*2 we are expanding their percentage of total product sales. These initiatives are being promoted not only by suppliers, but throughout the entire supply chain, including the business activities of our company such as purchasing, design, manufacturing and sales. In fiscal 2015, we reviewed and revised the Noritz Group Guidelines for Management of Substances with Environmental Impact. In fiscal 2016, we will carry out chemical substance management in accordance with these guidelines. Going forward, we will continue efforts to reduce substances with environmental impact in our products, while taking into account trends in laws and regulations.

*1 Noritz Group Guidelines for Management of Substances with Environmental Impact: Established in February 2005.
*2 Products compliant with hazardous substance standards = GP-compliant products: Products containing less than the prescribed concentration of 19 substances (the 6 substances covered by the RoHS Directive,*3 and 13 additional substances specified by our company). Applicable to: Water heaters, kitchen equipment, solar equipment, space heaters, and cogeneration equipment.
*3 RoHS Directive: A European Union directive banning the use of specific chemical substances contained in electrical and electronic equipment. Came into effect in July 2006. The applicable substances are: Lead, mercury, cadmium, hexavalent chromium, and two types of specified bromine-based flame retardants. The Noritz Group voluntarily applies this directive to water heaters and kitchen equipment.

System for guaranteeing that banned substances are not used
As a system for guaranteeing that banned substances are not used, we focus on building control systems at suppliers, and carry out the following management steps (1) through (4) when accepting incoming materials and parts. In this way, we provide a continual guarantee that hazardous substances are not used.

(1) Sign basic agreement with supplier
(2) Have supplier document their system and procedures
(3) Conduct auditing of chemical substances
(4) Analyze hazardous substances (check reliability of data)
