Climate Change

In order to achieve a decarbonized society, companies have an increasingly important role and responsibility to play. At the same time, the risks to business due to climate change, such as the frequent occurrence of natural disasters, have been increasing year by year.
SII has been striving to reduce greenhouse gas emissions through all of our business activities, including energy-saving activities at our manufacturing sites as well as the products and services our subsidiaries and affiliates provide. While continuing these activities, we further strengthen our efforts toward decarbonization by introducing renewable energy and other measures.

Long-Term Targets

In November 2023, Seiko Group Corporation, the parent company of SII, revised its long-term goal to reduce greenhouse gas emissions ahead of schedule. In alignment with this revised target, SII is actively working towards achieving a decarbonized society.

[Greenhouse gas emissions reduction target]^*

Fiscal Year 2030
　Scope 1 & 2:42% reduction compared to the FY2022 level.
　Scope 3:25% reduction compared to the FY2022 level, targeting categories 1 and 11.

Fiscal year 2050
Aiming for net zero.

^* Based on the "1.5℃ level" of SBT (Science Based Targets), a science-based greenhouse gas emission reduction target operated and promoted by SBTi (Science Based Targets initiative).

FY 2022 Overview

To reduce greenhouse gas emissions of Scope 1 and 2, SII is working hard on two key points, energy conservation activities and the introduction of renewable energy, to target both CO₂ and other greenhouse gases. In addition, SII is focusing on the creation of energy-conserving products within its green product system for both products and services.
Through its energy conservation activities, SII promotes the efficient application management of various equipment, capital investment in high-efficiency equipment, and familiar energy conservation activities. SII considers continuous implementation of these activities as important.
There are various kinds and means of renewable energy, but SII considers the adoption of the optimal methods for the plant site and characteristics as essential.

While SII was able to reduce energy consumption at domestic production sites through these initiatives in FY 2022, greenhouse gas emissions increased slightly, such as fluorocarbons. SII greatly reduced greenhouse gas emissions at overseas production sites. This was due to the expansion of renewable energy use and a reduction in production.

The use of solar power at an overseas site of Seiko Instruments (Thailand) Ltd. was expanded. As for sites in Japan, the use of PPA is now being considered for the Sendai plant. There are many types of PPA^*, and SII is planning to use the optimal method for the special characteristics of the plant.
As a member of the Seiko Group, SII is continuously engaged in disclosure of information and calculation of Scope 3 based on TCFD proposals.

■ In accordance with a review of CO2 emission factors, CO2 emissions prior to FY 2019 have been recalculated.
* For electricity, the "emission factor by electric utility" in the Law Concerning the Promotion of Measures to Cope with Global Warming is used.
* For fuels, the “calorific value by fuel type” and “emission factor for fuel use” in the Law Concerning the Promotion of the Measures to Cope with Global Warming are used.
* For hot and cold water, emission factors provided by suppliers are used.
* From FY 2020, tenants and company vehicles have been added to the scope of the calculation.
* For stores, warehouses, etc., where the amount of electricity used cannot be specified, the amount is estimated from the floor area.

■ FY 2022 includes HFC emissions due to fluorocarbons leakage. No emissions of HFCs, PFCs, SF₆, and NF₃ in the manufacturing process, although they are subject to control.
