Santen Group Guidelines for Environmental Conservation

Santen has established the "Santen Group Guidelines for Environmental Conservation" in order to promote and develop environmental conservation activities globally.

Environmental Management System

The company has established environmental conservation systems integrated with business activities at all Group companies. We address various environmental challenges and promote environmental conservation initiatives through every single employee's autonomous activities and promotes efforts to contribute to achievement of a low-carbon and recycling-based society. At the operational sites in Noto and Shiga, we have acquired ISO 14001 certification, which is the international standard for environmental management systems, and conduct environmental audits. The Suzhou Plant in China also acquired ISO 14001 certification in February 2019 and has started operations in accordance with the ISO 14001 requirements.

Environmental Vision for 2050

The company has established "Santen Vision for the Earth 2050" to fulfill its social responsibilities and strengthen the business foundation for its sustainable growth, with full recognition of conserving the global environment as one of the most important challenges. Under the vision, Santen makes a full commitment to the following two areas in all countries and regions of its operation. The first commitment area is "Measures against Climate Change", which are aimed at the achievement of net zero greenhouse gas emissions toward the Realization of a Carbon-free Society mainly through technological innovation toward an energy shift and thorough reuse and highly efficient use of resources at plants and other facilities. The second commitment area is "Environmental Load Reduction", which is aimed at the Establishment of a Recycling-based Society mainly through the full utilization of sustainable resources and materials based on technological innovation for all products.

Environmental Targets and Progress towards 2030 for Santen Vision for the Earth 2050

theme Targets Progress in FY2021
Measures against Climate Change
Contribution to a carbon-free society
  • 100% shift of company-owned vehicles to electric vehicles (HEVs, PHEVs EVs, and FCVs) by 2025
  • 100% shift of power used at plants and laboratories in Japan to renewable energy-based power by 2023
  • Facilitating wider use of transportation means with low environmental loads, including railroads, for commuting and business trips, and encouraging remote work and meetings
  • Promoting the initiative through engagement of major suppliers (in CO2 emissions reduction)
  • Shift of company-owned vehicles to electric vehicles in Japan : 92.3%
  • Completed conversion to renewable energy at plants and the laboratory in Japan, in February 2022
Targets
  • Scope 1 and 2 emissions(*1): 50% reduction by 2030 versus 2019 (SBTi's(*2)official validation as a target set in line with the Paris Agreement's(*3)1.5℃ target for 2050)
  • Scope 3 Category 1 emissions(*1)(non-consolidated): 15% reduction by 2030 versus 2019 (SBTi's official validation as a target set in line with the Paris Agreement's 2℃ target for 2050)
  • Scope 1 and 2 : 13.7% reduction compare to the base year (30,012 t-CO2)
  • Scope 3 Category 1: 12.2% increase compare to the base year (165,569 t-CO2)
Environmental Load Reduction (Measures for water resource and resource saving)
Conservation of limited resources, including water as the life of eye drops
  • Effectively utilizing resources through measures such as continuous reuse of water resources
  • Promoting the conversion of waste into valuables and waste recycling by continuing to completely separate waste by type
  • Ensuring the sharing and upscaling of good practices among operational bases
Targets
  • 12.4 m3/10,000 bottles of water consumption or less per unit of production
  • 98% or higher recycling rate
  • Water consumption per unit of production: 13.4 m3/10,000 bottles
  • Recycling rate: 98.5%
Environmental Load Reduction (Measures against plastic)
Reduce and shift from plastic, and become plastic-free
  • Reducing plastic consumption
  • Shifting from plastic to paper, biomass plastic and other new sustainable materials
  • Developing new sustainable materials through innovation toward solutions to technological challenges and the challenge of ensuring stable procurement
Targets
  • 60% of plastic eye drop containers being produced from biomass plastic in 2030
  • 15% reduction in plastic used for wrapping and package by 2030 versus 2019
  • Replacing to biomass plastic eye drop container: started replacing the container of five eye drop products and three of five products replacement had been completed
  • Investigating alternative means of plastic materials for packaging and packing materials
  1. Scope 1 emissions: Direct GHG emissions from sources owned or controlled by a company (fuel combustion and industrial processes)
    Scope 2 emissions: Indirect GHG emissions from the generation of purchased energy, such as electricity, heat, and steam
    Scope 3 Category 1 emissions: Scope 3 emissions denote indirect GHG emissions, other than Scope 1 and 2 emissions, resulting from a company's value chain activities, which are not owned or controlled by the company. Among them, Category 1 emissions are emissions from all purchased goods and services.
  2. SBTi (Science Based Targets initiative): A joint initiative to encourage companies to set and achieve science-based targets for GHG emissions reduction in line with the Paris Agreement
  3. Paris Agreement: An agreement within the United Nations Framework Convention on Climate Change, which has set the target of holding the increase in the global average temperature to well below 2℃ above pre-industrial levels, and pursuing efforts to limit the temperature increase to 1.5℃ above pre-industrial levels

Reduction of Greenhouse Gas (CO2) Emissions

The company makes efforts to reduce CO2 emissions aiming for net zero greenhouse gas emissions. the CO2 emissions in FY2021 was 30,012 ton which is 13.7% reduction from the base year due to the completion of conversion to renewable energy at plants and the laboratory in Japan. CO2 emissions per unit of revenue was 113 t-CO2/billion yen which is 21.7% decrease from FY2019. We also properly manage chlorofluorocarbons (CFCs), which have an impact on global warming, and are below the legal reporting standards in Japan, where the majority of our products are produced. In addition, with the setting of the 2030 target, the boundary and CO2 conversion factors have been revised to the SBT standard and retroactively revised from FY2019 onward.

Reduction of Greenhouse Gas (CO2) Emissions from our Supply Chains

In Japan, we assess not only Greenhouse Gas (CO2) emissions from Santen, but also those from Scope 3, in other words, our supply chains resulting from the purchase of raw materials, the distribution of products, and the movement of employees and strive to reduce CO2 emissions. In FY2021, Scope 3 CO2 emissions, which we began estimating in FY2016, amounted to 219,256 tons, 24.0% higher than in FY2020, and the emissions per unit of revenue were 1,149 tons per billion yen, a 20.9% higher compared to FY2020.

Grasping the Overview of Environmental Impact and Environmental Accounting

The company grasps the overview of environmental impact, comprised of input such as energy usage, input of materials, and input of water resources, and output such as release into the air and water, and the release of waste and other materials. It also grasps and analyzes the costs of environmental conservation efforts (investments and costs) and their effects (economic effects and environmental conservation effects) to promote effective activities for mitigating environmental impact.

Santen's non-consolidated environmental conservation costs of FY2021 include a total investment of 8.4 million yen and a total cost of 392.4 million yen, leading to 70.7 million yen of economic effects produced through environmental conservation.

Environment-related Accidents and Complaints

There was no accident that causes environmental pollution, i.e. soil contamination, and no infraction of laws or regulations related environmental issues, at our business sites in Japan or other countries in FY2021.
