Environmental Management

Environmental Management System

Tamagawa Seiki has established an environmental management system based on ISO 14001 and is advancing environmental improvement activities with a unified company-wide approach. Within the environmental management system, the execution leaders set environmental goals, and the environmental committee reviews progress and shares environmental issues, driving activities to address these challenges. The internal environmental audit team conducts annual audits to assess the compliance and effectiveness of the system.

Changes in CO₂ emissions

In order to achieve carbon neutrality, Tamagawa Seiki calculates the total energy consumption and CO₂ emissions associated with the manufacture of products and promotes activities to reduce them.

Total Energy Consumption^※1

※1　This is the total amount of energy (fuel and electricity) used by Tamagawa Seiki.

Scope 1^※2

※2　Scope 1 refers to CO₂ emissions from the combustion of fuel used by Tamagawa Seiki.

Scope ２^※3

※3　Scope 2 refers to CO₂ emissions derived from electricity used by Tamagawa Seiki.

・Scope 1 : Direct emissions of greenhouse gases by the business itself (fuel combustion, industrial processes)
・Scope 2 : Indirect emissions from the use of electricity, heat, and steam supplied by other companies
・Scope 3 : Indirect emissions other than Scope 1 and Scope 2 (emissions from other companies related to the activities of the business)

Initiatives to Prevent Environmental Pollution

Compliance checks, energy patrols

In order to prevent environmental pollution, the Environment Department and the Plant Management Department regularly patrol the plant to check the status of compliance with environmental laws and regulations. In addition, energy-saving patrols are conducted on an irregular basis for the purpose of energy management at sites.
