Environmental audit At MHI Group,two levels of audits are conducted including one by each domain, segment, and corporate unit on their respective organization as well as one by the environmental secretariat at MHI headquarters on the environmental management division of each domain, segment, and corporate unit. As a general rule, the respective domains, segments, and corporate units conduct internal environmental audits at the works, plants, and other facilities in Japan they oversee to ensure compliance with environmental laws and regulations and to conduct physical, on-site verification of operational conditions. Based on the Group's environmental policy, these audits confirm that environmental management associated with addressing climate change and pollution as well as water conservation have been properly employed. The environmental secretariat at MHI headquarters conducts audits on the status of compliance and environmental management of the environmental management division of each domain, segment, and corporate unit.
Environmental management in each site (Note 1) MHI Group has prepared and uses an ISO-based manual for each works (plants), encompassing such issues as risk identification methods, daily management procedures, and contingency plans.

Environmental activities

Fostering environmental awareness MHI formulates its own environmental education curriculum based on e-learning and other methods to provide environmental education to employees. In addition to the internal environmental auditor training program organized by our training center, specialized training that deals with daily management procedures and handling emergencies also takes place for employees doing painting tasks and handling dangerous materials.
Environmental Education for Suppliers Our "Action Guidelines" stipulate that we "strive to preserve the environment in partnership with our stakeholders and gain their understanding of this policy." Under this, we created a section titled "Respect for the Environment" in the MHI Group Supply Chain CSR Promotion Guidelines, and we communicate that content with our suppliers.
Activities for environmental
Supporting conservation survey for loggerhead turtles in danger of extinction
Promoting forest conservation and non-native species removal activities

Product Stewardship

Life-cycle assessment

Environmental Standards for Product Development and Assessment of environmental impact (Note 1) In 2005, we formulated the Basic Guidelines for Environment-Friendly Product Fabrication (not disclosed). This internal common technology standard provides a framework for creating products that contribute to environmental preservation and CO2 reduction. Under these guidelines, we assess the environmental impact of products across their life cycles and strive to create products that reduce environmental impact.
Reducing hazardous substances in products In accordance with the regulations of the countries and regions in which we provide products and services, we are working to reduce or eliminate hazardous substances in each of our businesses. For example, we are working to reduce the lead content of brass material bearings used in medium-and large-sized turbochargers for industrial machinery to less than 4% (the final target is less than 0.1%) in order to meet the customers' needs subject to the EU's RoHS Directive. This is an application exempt from RoHS Directive and the expiration date is 2024, so it will be reduced by 2024.
Reduction in CO2 from using MHI's products Every year, we calculate the amount of CO2 reduction achieved by the use of our representative products.
CO2 reductions the use of MHI Group's products (Note 2) in fiscal 2019 came to 61,438 thousand tons.
  • 1 In principle, MHI on a non-consolidated basis
  • 2Base lines were determined (base year / comparison target) in accordance with the characteristics of each product. Using these base lines, the amount of CO2 reduced through product use was calculated in accordance with such factors as the number of products in operation and the number of units sold in the relevant fiscal year.

Environmental product declaration

Environmental product declaration Since the majority of our products are industrial products for BtoB sales, we need confirmation with each customer regarding the precise details required for product tests, provisions, and contracts by going beyond the general Environmental Product Declaration in order to ensure the environmental standards and performance to be met. As for products for the general public (BtoC), we have air conditioners that are fully compatible with the Energy Saving Labeling Program authorized by the Ministry of Economy, Trade and Industry (METI) by meet 100% of the set energy-saving standards. In addition, certain centrifugal chillers, heat pumps, gas engines, and other units have been recognized with the L2-Tech certification of the Ministry of the Environment in Japan for their low-carbon technology.
% of revenue Less than 5%

Collection and recycling of used products

Collection and recycling of used products Although the majority of our products are industrial products targeted for business to business (BtoB) use, we promote product management throughout their entire life cycle, including disposal and recycling, through project stewardship centered on eco-design and eco-labeling.
As for products targeted for the general public (BtoC), air conditioners are subject to the Home Appliances Recycling Law of Japan, and are therefore collected in compliance with relevant laws and regulations. Furthermore, our rental forklifts are selected from registered Rental UP vehicles, inspected, and have parts replaced based on our in-company standards. These vehicles are then divided into three ranks according to replacement parts, painting, and warranty period for sale as a "certified second-hand vehicle." We are currently developing this business model as the first of its kind in Japan.
% of revenue Less than 5%
Recognizing Outstanding Environmental Contributions through MHI's Best Innovation Awards In fiscal 2017, MHI Group introduced its Best Environmental Product Awards and Best Environmental Practice Award as part of its "Best Innovation" in-house award program.
In fiscal 2019, the Best Environmental Product Awards were presented to two products including the plug-in hybrid transport refrigeration unit which reduces energy consumption and exhaust emissions and MEROS®, the dry-type multicomponent off-gas cleaning system for steel plants. Meanwhile, the Best Environmental Practice Award, which recognizes business activities that reduce environmental impact, was presented to the members of the Commercial Aviation Systems Division who successfully reduced VOC emissions in the process of manufacturing aircraft metallic parts through the development of solventless paint.
