Reduce Environmental Impact

Basic Approach

The Olympus Group is implementing a variety of environmental activities while assessing the environmental impact of its business activities with precision and with awareness of the scale of the impact on and risk to the environment. Also, following the diversification in our suppliers and with an awareness of climate change as a major environmental issue impacting our business activities, we continue to implement measures to assess information on energy conservation and regulations on reducing CO2 emissions and responding to sudden flooding.
At the same time, we actively develop and market environmentally conscious products that contribute to resolving issues with climate change and water risk and products designed to resolve environmental issues

CO2 emissions: reduced by: 21% (compared to FY2018)

Renewable energy rate: more than the previous year

The Olympus Group supports KEIDANREN's Commitment to a Low Carbon Society initiative and has set a target to reduce its energy consumption in FY2021 by 7.73% or more compared with FY2013. Among its energy-reduction activities is reducing its CO2 emissions. We arrange positions of experts and promote initiatives through our structure to promote energy saving at sites where energy consumption is high. In FY2021, continual improvements in manufacturing, energy-saving measures, updates company cars to environmentally conscious cars and the use of renewable energy were considered at its sites around the world. At the Hachioji Facility, lighting was upgraded to use LEDs and the temperature setting for the indoor storage of chemicals was reviewed to reduce energy consumption. The Hinode Facility updated its central air conditioning to use highly efficient equipment.
We have also been focusing on the construction and renovation of facilities. At Olympus Europa SE & Co. KG and Olympus Winter & Ibe GmbH, construction and renovation of facilities are underway with German Sustainable Building Council certification (DGNB certification*).
For wider use of renewable energy, studies are focusing on dissemination, economic feasibility and other factors in each country. The renewable energy use rate vis-á-vis the total electric power consumption has risen to 12.7% (compared to 11.7% in the previous year).
Olympus Corporation participates in the Carbon Neutral LNG Buyers Alliance as a part of new initiatives to reduce CO2 emissions, and has started to introduce carbon neutral LNG* to the Hachioji Facility.

*1 DGNB certification: Environmental certification for architectural structures issued by the German Sustainable Building Council to reduce the environmental impact of structures. Certification is given after assessment of the environmental performance of the building and confirmation that the structure satisfies certain criteria.

*2 Carbon neutral LNG: A type of LNG that offsets greenhouse gases generated in the processes from the extraction to the burning of natural gas with carbon credits created by environmental conservation projects.

External (Scope 3 [Category 4 Upstream transportation and distribution]) Results

FY2021 Results Main Measures
CO2 emissions: reduced by: 30.7%
(compared to FY2013)
  • Enhanced loading efficiency by improving packaging size and strength
  • Reduced transportation weights by improving packing and packaging methods
  • Shortened lead times and transportation distances by improving logistics routes

The Olympus Group is engaged in reducing logistics-related CO2 emissions at each of its sites. We continue with improvements, including optimizing the loading efficiency of transportation containers by products type and shape, consolidating logistics sites for transportation efficiency and direct shipping by reviewing logistics routes. In FY2021, CO2 emissions were reduced in a proactive modal shift from aircraft to ships for medical product transportation from Japan to the Americas and Australia.

Water Use/Wastewater Results

FY2021 Targets FY2021 Results Main Measures FY2022 Targets
Water use intensity:improve by 6% compared to FY2018 Water use intensity:improved by 14.1% compared to FY2018
  • Improvements in water use processes
  • Implementation of secondary use of water
Water use intensity: improve by 7% compared to FY2018

The Olympus Group uses water mainly in production processes, such as for cleaning components and cooling, as well as in its dining halls. We implement thorough wastewater control by adopting stricter standards than the legal requirements in each region, and we continue to reduce water consumption and wastewater emissions by setting targets in those sites that have high water consumption. We are also acting to conserve water resources under collaborations with local communities at each site.
In FY2021, we reassessed the water risks at each of our sites using water risk assessment tools (e.g. Aqueduct), hazard maps, and their water usage. In Japan, Olympus Terumo Biomaterials started using the residue from generating RO-purified water*1 for toilets and sprinklers, and Aizu Olympus reduced water usage by shortening the time taken to wash parts. To conserve regional water resources, the Nagano Facility discharges wastewater into the nearby Tenryu River with the approval of the local fisheries cooperative association. The wastewater discharge is strictly controlled and regularly monitored by the facility to minimize any impact on the river habitat. The Nagano Facility also helps maintain the local forest that serves as a water source for the area under a Forest Fostering Agreement concluded with the Monzen Forest Association and Tatsuno Town in Nagano Prefecture. Olympus Surgical Technologies America (formerly Gyrus ACMI, Inc.) in the U.S. received a Commitment-to-Compliance Award*2 for two consecutive years in recognition of long-time efforts to maintain compliance with the industrial wastewater discharge permit requirements set by King County, Washington.

*1 Nearly 100% pure water filtered using a reverse osmosis (RO) membrane.

*2 Presented to companies that have received a Gold Award for five consecutive years in the recognition program in King County, Washington, to meet or exceed wastewater discharge permit requirements.

  • Extracting valuable materials from wastes
Emission intensity: improve by 7% compared to FY2018

The Olympus Group is working continually on reducing losses in manufacturing processes by making improvements to them and efficient use of resources, including thorough waste separation to reduce waste discharge, extract valuable materials and promote recycling.
In FY2021, paper usage was significantly reduced in our development sites and offices due to digitalization associated with increased remote working progressed by our Work Style Reform. In Japan, Shirakawa Olympus extracted valuable materials from waste organic solvents and components. Olympus Logitex reduced waste packaging by expanding the use of returnable containers and reuse of cushioning materials, and by replacing disposable stretch film to prevent load shifting with recyclable packaging bands. In the U.S. Olympus Surgical Technologies America Inc. provided an intra-company awareness raising program to help employees increase the recycling rate. The company's Bartlett office signed up to the Tennessee Recycling Coalition*1 and Tennessee Materials Marketplace*2 to explore new ways of recycling, and open and expand the reuse and recycling market.
Our hazardous waste emissions have been reduced compared to FY2020 by reinforcing waste management and replacing certain chemical substances with safer ones.

Product Life Cycle Assessments

The Olympus Group works to develop products and production technologies that show consideration for safety and for the environment. Having in FY2004 established its Eco-Products Administration Rules, a voluntary standard relating to the environmental considerations of our products, we continue to certify our products as Olympus Eco-Products.
In addition, a life cycle assessment (LCA) is performed at each stage of a product's life cycle to assess its impact on the environment at the product development stage and from procurement through manufacture, distribution, use and final disposal. Clarifying the environmentally conscious aspects that differ for each product, we have set them as items for the environmental consideration standard.
We are working to reduce the use of containers and packaging materials, and promoting effective use of resources.
