The ROHM Group Environmental Vision 2050

The international community and the governments have issued strong guidelines for a carbon-free society, such as the Paris Agreement that states that the average global temperature rise should be kept below 2 ℃ above the pre-industrial levels, and the 2050 Carbon Neutral. Looking at society, problems such as climate change, resource depletion, and biodiversity loss are becoming more serious. Planetary boundaries that objectively assess the impact of human activities on the Earth's system show that climate change, biodiversity loss, and chemical pollution go beyond acceptable levels. It is clear that the negative impact of economic activities on the planet has already reached levels that threaten the safety of human society.
ROHM has been promoting the reduction of environmental impact through its business activities and products in accordance with its corporate philosophy and environmental policy.
Based on the above situation, we set up the the ROHM Group Environmental Vision 2050 in 2021 in order to make a strong commitment to pass on the global environment to the next generation in a better condition. We have set three important themes - climate change, resource recycling and coexistence with nature, and have also formulated the "2030 target", which is an intermediate step.

The ROHM Group Environmental Vision 2050

Climate Change

Climate change is one of the most important social issues that the global society is facing. The Paris Agreement requires to keep the global average temperature rise well below 2 ℃ above the pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 ℃.
At the same time, balancing greenhouse gas (GHG) emissions and absorption in the second half of this century to realize a carbon-free society is also an important theme for companies. To realize a carbon-free and low-carbon society, semiconductors, ROHM's main product, are playing an increasingly important role, and improving efficiency of motors and power sources, which are said to account for most of the world's electricity consumption, is a major mission for ROHM.
In addition to contributing through these products, it is also important to reduce the environmental impact of all business activities such as the production process.
ROHM recognizes climate change countermeasures as an important management issue, and will work to build an environment-friendly business structure by promoting energy conservation and the introduction of renewable energy in all business activities.

Resource Recycling

Mineral resources, which are also raw materials for semiconductors, are used in a wide variety of fields such as communication equipment and precision machinery and are indispensable for human life. Due to the remarkable progress of society, it has continued to expand rapidly in the last 40 years, and the material footprint per capita in the world increased from 8.26 tons in 2000 to 12.18 tons in 2017. We are facing the problem of exhaustion. Some resources will be mined and used up in less than 100 years. Therefore, effective use of resources and resource conservation are important issues for ROHM's business activities. Water, one of the natural capitals, is also the most important resource for our corporate activities. As global warming progresses, there are concerns about procurement risks due to droughts and the seriousness of disasters caused by floods around the world, but if effective measures are not taken, the supply and demand for freshwater resources is expected to become increasingly tight. Recognizing the impact of business activities on the environment, ROHM is working on resource recycling as much as possible, reducing waste and improving water recycling rates in order to reduce the waste of limited resources throughout its business activities.

Coexistence with Nature

Biodiversity is a source of various resources for us people, such as food, lumber for paper and building materials, water, and the atmosphere. At COP25 (25th Conference of the Parties to the Framework Convention on Climate Change) held in December 2019 to discuss measures to prevent global warming, it was reported that about 20,000 species of wild animals had become extinct during about 20 years from 2000. If no action is taken and ecosystems continue to be lost due to deforestation, environmental pollution by chemical substances, global warming, it is expected to have many negative effects, including floods, droughts, poor food harvests, poor fishing and worsening climate change. ROHM aims to be in harmony with the natural environment, deeply recognizing that we are blessed by the biodiversity of the earth. Specifically, we will thoroughly manage product chemical substances and carry out biodiversity conservation activities throughout the Group to promote the creation of a global environment that will be passed on to the next generation.

In order to accelerate our efforts to realize the above vision, ROHM is also participating in international environmental initiatives. Toward 2050, the year of achievement, ROHM will make steady progress toward the goal while setting mid-term environmental targets in stages.

Promotional System

ROHM Group has been working to continuously improve environmental issues by establishing and operating an environmental management system across the entire Group based on ISO 14001 international standard for environmental management systems.
The efforts are led by an Environmental Conservation Management Committee established at ROHM Head office, which manages the environmental impact of ROHM products, activities, and services, and recommends any points for improvement found in separate internal audits of ROHM sites horizontally to the other Group companies.

The Environmental Conservation Management Committee is a subordinate organization to the EHSS General Committee*, in which directors with executive authority and divisional managers participate, and is responsible for the appropriate management of serious environmental risks within ROHM Group.

The Environmental Conservation Management Committee is chaired by an executive officer, and its specialized subcommittees are working on various themes, such as climate change, effective use of resources, chemical substance management and biodiversity conservation, manage environmental risks in cooperation with the Environmental Management Department, which serves as the secretariat. Each specialized sub-committee formulates goals, measures and evaluations for each topic and regularly reports progress and results to the Environmental Management Committee. The EHSS General Committee also evaluates and confirms that the Committee's PDCA cycle is properly implemented and that a system is in place to maintain and improve the accuracy of the management system.

Integrated ISO14001 certification has been obtained by all Japanese Group companies and ROHM KOREA.
Some of our overseas production sites have developed environmental management systems, based on the self-declaration of ISO14001 standards. The environment management staff at ROHM Head Office strictly evaluate and approve the appropriateness of those self-declarations based on a common manual for maintaining a management systems the same way as the sites certified by a third party.

Application for Environmental Management System

EHSS (Environment, Health and Safety, Sustainability) General Committee:
A committee composed of the executive officers of management that oversees the eight lower management systems (environment, health and safety, labor, ethics, information, supply chain, quality, and risk management BCM) and ensures that the PDCA cycle for each is properly implemented.
