Measures against Climate Change

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

Each workplace takes the initiative in conducting regular internal audits to check whether the environmental management system is appropriately operated. Additionally, Santen accepts on-the-spot audits by commissioned companies of the process of commissioned production, providing good opportunities to learn about other companies' efforts, and contributing to improving our environmental measures.

 

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.

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

The company makes efforts to reduce CO₂ emissions aiming for net zero greenhouse gas emissions. The CO₂ emissions in FY2021 was 30,012 tons 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 SBTi standard and retroactively revised from FY2019 onward.

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, 20.9% higher compared to FY2020.
 

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.
 

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.
