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 2018

Targets
Reduce FY2018 global greenhouse gas emission (PFC's, SF6, and etc.) by 1.0% from currently predicted value according to the quantity of production of FY2018.
Results
FY2018 global greenhouse gas emission (PFC's, SF6, and etc.) was reduced by 24.6% from currently predicted value according to the quantity of production of FY2018.
Reduce Global Greenhouse Gas Emission

Midterm and Long-term Target Setting

The Paris Agreement, which aims to keep the global temperature rise below two degrees Celsius above pre-industrial levels became effective, and activities to realize a post-carbon society have been accelerating globally.
The ROHM Group, also regards the establishment of medium- and long-term Science-Based Targets (SBTs) for 2030 and 2050 to be one an important task in the bid to reduce greenhouse gases for the entire supply chain. Consequently, the Group launched the Subcommittee on Climate Change in fiscal year 2018, and began to survey current conditions and investigate goals for the establishment of SBTs.

2.CO₂ Countermeasures through Value Chain

To reduce the level of CO₂ emissions from all business activities, ROHM expanded the range of its estimates to cover Scope 1 and 2 as well as Scope 3, calculating CO₂ emissions for the entire value chain.
With a goal of resolving social issues through innovative products, we strive to develop ECO- friendly products.

Reducing Waste

Throughout the flow of its business activities, from procurement of materials to development, production and sales, the 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 2018

Targets
  • Maintain zero emission in domestic group consolidated and maintain waste generation (per production unit) inFY2018 as the results of FY2017.
  • Maintain waste generation(per production unit) in overseas group in FY2018 as the results of FY2017.

  • Waste generation (per production unit) in overseas group was reduced by 1.3% from the actual results of FY2017.

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 2018

Targets
Reduce water input volume by 1% in FY2018 from the predicted value according to the quantity of production of FY2018.
Results
Water input volume was reduced by 9.2% from the predicted value according to the quantity of production of FY2018.
TOPICS.
Water Risk Correspondence
The semi-conductor manufacturing process, which is one of the 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.
