Shin-Etsu Silicones of America acquired ISO14001 certification at all manufacturing sites in April 2025.

sustainability_report p.12

Stated goal to become carbon neutral by reducing Scope 1 and 2 GHG emissions to net zero by 2050. In FY2023 the Carbon Neutral Task Force formulated a specific plan for achieving carbon neutrality by 2050, which was discussed and unanimously approved at the Managing Directors' Meeting.

sustainability_report p.7

Reports alignment with multiple SDGs including 2 (Zero Hunger), 3 (Good Health), 6 (Clean Water), 7 (Affordable & Clean Energy), 8 (Decent Work), 9 (Industry & Innovation), 11 (Sustainable Cities), 12 (Responsible Consumption), 14 (Life Below Water), 15 (Life on Land), 16 (Peace & Justice).

sustainability_report p.6

Modal shift from road/air to rail/ship for methanol, silicon wafers, and silicone products; acquired Eco-Rail Mark company certification. Started recycling product shipping cartons for heat-dissipating silicone grease, eliminating need for dry ice and reducing supply chain CO2.

sustainability_report p.70

The largest decarb lever, accounting for ~54% of planned reductions, is purchasing hydroelectric and low-carbon electricity (e.g., Gunma PPA covers 100% of Yokonodaira Plant electricity, cutting that site's GHG by ~90%), installing solar PV at multiple plants, and transition of electric power companies to carbon neutral.

sustainability_report p.66

Continuous productivity improvement, reaction efficiency improvement, heat pump utilization, heat recovery in raw material production, high-efficiency equipment, increased use of charcoal reducing agents, and transition to new manufacturing processes. New silicone intermediate manufacturing method introduced in 2023 cut energy by 48% and GHG by 47% vs. previous method.

sustainability_report p.48

Material recycling of PVC (60% of used PVC pipes/joints recycled into new pipes, 70% of agricultural film into flooring). Rare earth magnet recycling since 2007 from internal scrap and since 2013 from end-of-life appliances and hybrid cars, including a partnership with Toyota Motor Corporation to recycle neodymium and dysprosium from HEV motors. Shintech achieved +Vantage Vinyl Silver certification supporting U.S. vinyl industry recycling.

sustainability_report p.81

Introduction of carbon capture plant and utilization (CCU) is targeted for the 2030–2050 phase, contributing ~6% of the carbon-neutral plan. The Naoetsu Plant is investigating advanced technologies for waste heat recovery and CO2 recovery.

sustainability_report p.66

Consummated the acquisition of the full ownership of Mimasu Semiconductor Industry to support semiconductor materials business expansion.

sustainability_report p.4

In FY2024, Shin-Etsu Chemical received a CDP climate change evaluation of A-. Also recognized as Supplier Engagement Leader 2024.

sustainability_report p.21

In May 2024, Human Rights Policy was reviewed and revised based on the UN Guiding Principles on Business and Human Rights, following approval by the Managing Directors' Meeting.

sustainability_report p.97

The Group's 2050 carbon-neutral mix shows carbon offsets at ~9% and CO2 recovery/reuse (CCU) at ~6%, with the remainder from electricity decarbonisation (54%) and manufacturing improvements (31%). Specific measures listed include tree planting and carbon offsets, plus a planned carbon capture plant. Removals are positioned as a last-resort, post-2040 lever rather than the primary route.

sustainability_report p.67

Switching from heavy fuels to natural gas, then to carbon-neutral natural gas (with emission credits), green/blue hydrogen, biomass fuel, and ammonia. Cogeneration systems using natural gas at Gunma Complex (2 new gas turbines at Isobe + 1 at Matsuida added Nov 2022, saving ~24,000 tCO2/year and achieving 100% self-sufficiency) and Naoetsu Plant.

sustainability_report p.66

Shin-Etsu participates in Gunma Prefecture's 'Local production for local consumption PPA' (Gunma Model), receiving hydroelectric power that will cover all electricity used at the Yokonodaira Plant and cut its GHG by ~90%. Installed solar panels at Goubara (148 kW), Isobe (new in July 2023, 155 MWh/year), Takefu (137 kW, 125 MWh/year) and Shin-Etsu Magnetics Philippines (~1,200 kW, ~1,500 MWh/year, -1,026 tCO2/year). In Thailand, three Group companies will receive biomass cogeneration renewable energy from NSET starting 2027 under the JCM Model Project (~48,000 tCO2/year reduction).

sustainability_report p.68

Participated in Roundtable on Sustainable Palm Oil (RSPO) since February 2021 and obtained mass balance certification in March 2023 to promote sustainable palm oil procurement.

sustainability_report p.87

Refined calculation of greenhouse gas emissions and revised the Scope 2 emissions for FY2023 (originally disclosed in July 2024).

sustainability_report p.63

With enforcement of revised PRTR Law, silicon carbide and other substances became Type 1 designated chemical substances subject to reporting from 2023 onwards, resulting in significant increase in total transferred volume of PRTR controlled substances.

sustainability_report p.88

Reduce greenhouse gas emissions in terms of production intensity to 45% of FY1990 level by FY2025 (i.e., 55% reduction).
