The Daiichi Sankyo Group is striving to use resources and energy efficiently under the EHS Management Policy(FY2021-FY2021), which states, “Lower the environmental impact of the entire supply chain by conserving energy and resources, and reducing greenhouse gas emissions and waste”. To facilitate responsible corporate activities that address climate change, we have set the goals of reducing CO2emissions in FY2025 by 42% and in FY2030 by 63% compared to FY2015 based on the approach of the Science Based Targets initiative (SBTi)*1, which aims to help accomplish the goal of the Paris Agreement (keeping the average increase in global temperature below 1.5°C compared to pre-industrial revolution levels). At Daiichi Sankyo Chemical Pharma Onahama Plant, we completed construction of a new office building in March 2023 and acquired the Daiichi Sankyo Group’s first “Nearly ZEB*2” certification under the Building-Housing Energy-efficiency Labeling System (BELS)*3. Daiichi Sankyo Pharmaceutical (Shanghai) Co., Ltd. followed the Onahama Plant and Daiichi Sankyo Europe’s Pfaffenhofen Plant in putting its solar power system into operation. In April 2022, we switched to renewable electricity (FIT non-fossil fuel energy certificates with tracking) for the electricity we use in 13 sites in Japan, including our head office, production sites, research laboratories, and training facilities. Moreover, operating sites in Europe and Brazil have reduced CO2 emissions by expanding the use of renewable energy. We are continuing our efforts to further utilize renewable energy at our operating sites globally.
Our CO2 emissions for FY2022 were 109,735 tons (49.6% lower than in FY2015). Not limited to our efforts to “mitigate” CO2 emissions and other environmentally hazardous actions, we facilitate initiatives to “adapt” to impacts that have become tangible or influence that is inevitable in the medium- to long-term.

CO2 Emissions Reduction Targets and Performance
CO2 emissions for FY2022 were 109,735 tons, a 49.6% reduction compared to FY2015. This is 81,664 tons less than the FY2021 performance of 191,399 tons, due primarily to the switchover in Japan to renewable electricity (FIT non-fossil fuel energy certificates with tracking information) (approximately 67,500 tons).
By scope, FY2022 performance for the entire Group was 86,006 tons for Scope 1 and 23,729 tons for Scope 2, which were 3.8% and 75.3% lower than in FY2021, respectively. The CO2 emissions for Scope 3 in FY2022 totaled 2,122,492 tons, 9.0% higher than the 1,947,668 tons of FY2021. This was largely due to an increase in purchased goods and services (category 1). Also, the CO2 emission intensity (based on net sales) was 141.5 (t-CO2/billion yen), an improvement of 12.4% from 161.5 in FY2021.

CO2 Emissions Reduction Initiatives
Initiatives at plants and research facilities
We select and install highly efficient energy-saving refrigerators and boilers when upgrading equipment, and implement measures to reduce CO2 emissions such as installing heat insulation on steam piping, improving the efficiency of air conditioning operation, and using natural light by making use of optical ducts.
Initiatives at offices
At office buildings, energy-saving is promoted by installing LED lights and motion detectors throughout buildings.In addition, measures to reduce energy consumed at offices are actively implemented, such as wearing casual business clothing throughout the year, ensuring the lights and air conditioners are turned off in unused meeting rooms, and recommending employees to leave work on time by optimizing schedule management.In respect to employees’ travels between operation sites, efforts are being taken to reduce domestic and international business trips by further improving and utilizing video conference system.

Utilization of Renewable Energy
At Daiichi Sankyo Europe Pfaffenhofen Plant in Germany, which has been converting all purchased electricity to electricity generated from renewable energy since 2014, a self-consumption solar power system (annual energy production of 580 MWh)constructed on the plant’s premises began operation in February 2022. In addition, in January 2023, the Daiichi Sankyo Pharmaceutical (Shanghai) Shanghai Plant began using a solar power plant (with annual energy production of approx. 540 MWh), which is able to cover the annual energy consumption of the plant’s administrative building. This is expected to reduce CO2 emissions by 300 tons per year.
In addition, at Daiichi Sankyo Chemical Pharma Onahama Plant, which started operation of the solar power system with annual energy production of approx. 4,000 MWh in December 2020, finished construction of the Daiichi Sankyo Group’s first Nearly ZEB-certified building, its new office, in March 2023. This office generates electricity using solar power and saves energy by effectively combining high-efficiency air conditioning, water heating, and lighting equipment, thereby cutting standard building energy consumption by 78% (51.9% from energy savings and 26.9% from energy generation).
From April in FY2022, we are actively promoting the utilization of renewable energy by, for example, switching to renewable energy (FIT non-fossil fuel energy certificates with tracking information) for the electricity we use in 13 sites in Japan, including our head office, production sites, research laboratories, and training facilities.

Supplementary Notes
Conversion factors and their sources
Conversion factors of the Accounting and Reporting System under the Act on Promotion of Global Warming Countermeasures are used for the CO2 conversion factor and the energy conversion factor.
Regarding countries outside Japan, the factors commonly used in such countries or the factors based on GHG protocol are used.
Emissions not in the calculation
The emission data does not include emissions in Scope 1 or Scope 2 from small offices outside Japan. Also, it does not include emissions of GHGs other than CO2, as they are small in quantity.
GHG emissions from sold products
Any use of sold products will not help reduce GHG emissions.

Improving credibility of the environmental performance data
Aiming to improve the credibility of the information disclosed to stakeholders, Daiichi Sankyo receives third-party assurance for its environmental performance data. When aggregating the environmental performance data, we strive to improve the accuracy and credibility of the data disclosed by inputting highly objective data in principle, based on evidence issued by third parties, such as purchasing slips.
Emissions Trading
The Shinagawa R&D Center and Kasai R&D Center are among the facilities subject to the mandatory emission reduction scheme and the emissions trading system, Tokyo Cap and Trade Program, under the Tokyo Metropolitan Ordinance on Environmental Preservation. Daiichi Sankyo Biotech is also among such facilities under the Saitama prefectural government's global warming countermeasures ordinance. Recognized for their particularly outstanding measures to combat global warming, the Shinagawa R&D Center and Kasai R&D Center were certified as a “near-top-level facility” in fiscal 2019 and fiscal 2020, respectively.
