Midterm and Long-term Target Setting

Hence the Paris Agreement entered into force , which requires to limit global temperature increase below 2℃ compared to the pre-industrial temperature, activities to realize a post-carbon society have been accelerating globally.
There are many social problems around the world such as water risks and marine plastic problems.
ROHM Group considers these social issues as our own issues and setting medium- to long-term goals for 2030 and 2050.
For reduction of greenhouse gases, we are working on examining specific target values to set science based targets (SBTs).

Reduce Global Greenhouse Gas Emission (PFCs, SF6, and etc)

PFC gas is a material essential for fine processing of semiconductors, especially Ics. This PFC gas will turn to a greenhouse gas that produces greenhouse effect 6,500 times as high as CO₂ when it is released into the atmosphere. The semiconductor industry has determined a target for reduction in the PFC gas emission and promoted the installation of PFC gas treatment systems used to dissolve PFC gases and eliminate the greenhouse effect.

Fiscal Year 2019

Targets
Reduce FY2019 global greenhouse gas emission (PFC's, SF6, and etc.) by 0.5% from currently predicted value according to the quantity of production of FY2019.
Results
FY2019 global greenhouse gas emission (PFC's, SF6, and etc.) was reduced by 26.3% from currently predicted value according to the quantity of production of FY2019.

Reducing Waste

Throughout the flow of its business activities, from procurement of materials to development, production and sales, ROHM Group strives to eliminate the wasteful use of finite resources and energy, reduce waste, and promote recycling. Toward this end, led by the Resources Use Expert Sub-Committee, it sets targets and formulates implementation plans for each year, and pursues related activities. We are also continuing to achieve zero emissions.

Fiscal Year 2019

Reducing Waste

Water Consumption

ROHM group expands the semiconductor wafer manufacturing consumes a large amount of water in domestic and overseas.
The raw water input for semiconductor manufacturing is high cost resources used after processing hyper pure water, so it is necessary to not disposable but recycle or reuse for water-saving efforts.
We consider it is obvious that reducing input of limited water is friendly to environment, and reducing risk of business continuity can be possible if water-saving measure works even if water shortage is happen by climate change.

Fiscal Year 2019

Targets
Reduce water input volume (per production unit) in FY2019 to below the actual results of FY2018.
Results
Water input volume (per production unit) in FY2019 was increased by 5.2% from the actual results of FY2018.
Water Consumption
TOPICS.
Water Risk Correspondence
The semi-conductor manufacturing process, which is one of ROHM Group's business areas, consists of an upstream process (semi-conductor wafer process) and downstream processes (assembly and final product inspection). The upstream process is located in Japan, and the downstream processes are located in our Southeast Asia, South Korea, and China plants. The manufacture of semi-conductors is an industry that requires the use of large volumes of ultra-pure water. The vast majority of those resources are used in the upstream process. For this reason, securing a long-term, stable supply of water in Japan, where the upstream process is concentrated, is an essential prerequisite for the continuation of operations.
Further, in Southeast Asia, where most of the downstream processes are concentrated, the two plants in Thailand are located in catchments with a high risk of flood and other water damage. From the bitter past experience of having operations disrupted by actual damage from a flood disaster, we conduct risk management from the dual aspects of water shortages and flood risk.

Environmental Education for Elementary School Students

ROHM Group has provided environmental education for elementary school students in Kyoto-city from FY 2010. In the education program, we give the opportunities for them to experience the energy-saving effects such as comparing the energy-consumption of LED and miniature bulbs by using a human powered generator besides the lecture about global-warming's mechanism, and energy-saving tips that can be performed at home or school.
ROHM Group will continuously develop these kinds of activities that help children understand the value of global environment.
In 2019, we provided environmental education to 100 students from two different elementary schools, and so far, a total of approximately 1,700 elementary students have received our environmental education.
