Measures against Climate Change

Santen makes efforts to reduce CO₂ emissions aiming for net zero greenhouse gas emissions.

The CO₂ emissions in FY2022 was 22,619 tons which is 24.6% reduction from FY2021 due to the completion of conversion to renewable energy at plants and the laboratory in Japan by February in 2022. CO₂ emissions per unit of revenue was 81 t-CO₂ per billion yen which is 28.3% decrease from FY2021. 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 FY2022, Scope 3 CO₂ emissions amounted to 133,451 tons, 8.2% higher than in FY2021, and the emissions per unit of revenue were 679 tons per billion yen, 5.0% higher compared to FY2021.

In the renewal of facilities at plants that use a large amount of energy, we promote the introduction of equipment with higher energy consumption efficiency, leading to a reduction in environmental impact through energy conservation and conversion. In addition, we are seeking specific action plans, such as further conversion to electricity derived from renewable energy sources, conversion of energy sources, and technological innovation for high-efficiency use, with the aim of realizing a decarbonized society.
