Reduction of Greenhouse Gas (CO2) Emissions

Santen has adopted a policy of continuing its efforts to reduce CO2 emissions, which account for the majority of greenhouse gases emitted by the group, into the future even as our production grows, and has set a medium-term target of 10% reduction of group-wide CO2 emissions in FY2020 compared with FY2005. As a result of proactive efforts to replace old combustion-based equipment with non-combustion-based equipment, and saving a larger amount of energy by introducing high-efficiency equipment, we succeeded in reducing CO2 emissions in FY2020 to 31,320 tons, 18% lower than in FY2005. The consolidated emissions per unit of revenue were 125tons per billion yen, 27% lower than in FY2016. We also appropriately control CFC gases that can affect global warming, and our CFC gas emissions are below the legal and regulatory standards for reporting in Japan, where we generate most of our CFC gas emissions.

With regard to our operations in Japan, which account for 77% of our total CO2 emissions, we have participated in the low-carbon society action plan of the Federation of Pharmaceutical Manufacturers' Association of Japan since 2013, and have been striving to achieve our medium-term target of reducing FY2020 CO2 emissions from our domestic operations by 30% from FY2005. Santen's domestic CO2 emissions in FY2020 were 24,224 tons, 32% lower than in FY2005.

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 FY2020, Scope 3 CO2 emissions, which we began estimating in FY2016, amounted to 176,819 tons, 3.3% higher than in FY2019, and the emissions per unit of revenue were 950 tons per billion yen, a 1.3% higher compared to FY2019.

Grasping the Overview of Environmental Impact and Environmental Accounting

Santen 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. Santen 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 FY2020 include a total investment of 53.8 million yen and a total cost of 285.4 million yen, leading to 71.5 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 FY2020.
