ISO 14001 Certification acquired across the entire Mitutoyo Group
The Mitutoyo Group is actively engaged in environmental conservation activities with the aim of becoming
company that can coexist in harmony with society.
Until 2012, each business division had established its own voluntary environmental management system,
however in order to further reduce our environmental impact, we established company-wide environmental
management system in 2013 and obtained ISO 14001 certification for the entire Mitutoyo Group.
The registration certificate is posted on the Mitutoyo homepage under Environmental Initiatives.

Examination scene

Internal Audits
Mitutoyo also conducted mutual audits among site, in which auditors from one site visit another site to conduct
audits. In fiscal 2022 , it was carried out at the Kure Plant (indirect department).
Purpose of mutual audits among site
To match the level of audits , and to make suggestions for operational improvement based on cases at other site.
Sites subject to mutual audits in fiscal 2023 (Divisions) :Kochi Plant （all divisions）、Nakatsugawa Plant（Manufacturing Division）

Carbon Neutral Initiatives
1. Commitment
The Mitutoyo Group will contribute to the realization of a decarbonizedsociety toward carbon neutrally by 2050 to fulfill its corporate responsibility
to address global climate change issues.
●We will reduce our Co2 emission ( Scope 1, 2 ) by 50% from 2018 levels
by 2030.
●We formally endorsed TCFD’s recommendation in Sep 2022.
*TCFD (Task Force on Climate-related Financial Disclosures）

2. Specific Initiatives
The Mitutoyo Group is actively making efforts to “ Use renewable energy “ and “ Introduce energy-saving andhighly efficient production equipment “ to achieve the world most competitive “ Made in Japan “manufacturing.
We will continue to meet the growing demand for precision measuring instruments while future accelerating
the reduction of Co2 emissions throughout the entire value chain.

Example of Initiative

We are switching to 100% CO2-free hydroelectric power generation in the Utsunomiya Operations and at our
Kochi Plant.
●Kochi Plant
Introduction of “Kochi
Support Electricity”●Utsunomiya Operations
Introduction of “TochigiFurusato Electric power
Supply Service”

Initiatives to Reduce Environmental Iｍpacts
1. Efforts to Reduce Energy Consumption
With the perspective of promoting the efficient use of electricity, fuel and other energy sources, we are switchingto energy-saving equipment and enhancing energy-saving systems upon the upgrading of our equipment.
Concurrently, through improvement in our business activities, we are striving to improve the efficiency of energyuse.

Major capital investments related to power
energy conservation- Installation of energy-saving compressors and air
monitoring system.
- Introduction of high-efficiency air-conditioning
systems and renew of air-conditioning specifications- Installation of power monitoring devices- Use of LED for lighting fixture

Major improvement related to energy
conservation- Reduction of waste parts and streaming of operations
by improving manufacturing quality- Construction of production line to cope withproduction fluctuation- Reduction of paper document and improvement ofwork efficiency through IT technology- Promotion of reuse of packaging materials for large
equipment

Initiatives to Reduce Environmental Iｍpacts
2. initiatives for Recycling and Resource Recovery of Waste Materials
The Mitutoyo Group recycles waste as valuable resources, reducing its volume, and resource recovery.

Examples of Major Initiatives for Waste Reduction- Use of returnable containers for parts transport- Adoption of specialized transportation jigs and reuse of packaging materials- Return of containers for purchased goods (pails and drums)- Extending the service life of coolant liquid by using preservatives and floating oil separators- Reuse of used office files, etc.・- Common use of wooden packaging boxes for domestic and export use- Selling used computers to specialized companies- Dedicate processing machines for different materials and sell chips as scrap

Examples of Major Initiatives for Improve Recycling Rates- Reducing food loss by turning food waste from the company cafeteria into feed
- Waste plastics⇒ Materials, thermal recycling- The wood pallets used for transportation are crushed
and turned into chips by a processing company andused as raw material for papermaking or fuel- Compressed briquettes from grinding sludge⇒ Recycling- Recycled etching waste liquid from scale
manufacturing equipment- Recycle wastewater with ion exchange tower( Regenerates into pure water and returns to line)- Reuse through closed wastewater treatment(Plating line, scale manufacturing, water jet cutter)- Recycling by returning used whetstones to manufacturers

3. Initiatives for Soil and Groundwater Remediation at Kawasaki Operations
Since soil and groundwater contamination was detected at the Kawasaki Operations in 1991, efforts for
purification have been conducted by pumping groundwater to prevent off-site discharge and by vacuum
extraction of underground gases. In February 2008, a surface gas survey and borehole investigation wereconducted over the entire site (excluding areas where it was difficult for the survey to be conducted), and areport was submitted to Kawasaki City in August 2008, along with a plan for future countermeasures.
The progress of the countermeasures to date is outlined below.
