Mitigating and adapting to the threat posed by climate change requires active involvement on all levels including national governments, local governments, corporations and citizens. Astellas recognizes that climate change will become a constraint on conducting sustained corporate activity, and considers it one of management's most important problems to address.

To achieve the 2°C target of the Paris Agreement, Astellas adopted the recommended method for setting reduction targets and formulated a new Environmental Action Plan in light of the national and corporate promotion of international initiatives such as the Science Based Targets (“SBT;” reduction targets consistent with scientific knowledge).
We will also focus on the risks and opportunities that climate change will present to our business, and promote our efforts from a medium- to long-term perspective.

Toward the Reduction of Scope 2 emissions

In order to reduce the indirect emissions associated with externally supplied energy, Astellas employs a “market-based method” that uses emission coefficients for each electricity company from which Astellas actually receives a supply.
Emissions in regions where it is difficult to use the emission coefficients for each electric power company are calculated with country-specific emissions coefficients provided in the CO2 EMISSIONS FROM FUEL COMBUSTION 2017 EDITION published by the International Energy Agency.
Moreover, we are purchasing electricity generated by renewable energy sources at plants and other facilities in Europe.


Our Efforts to Reduce GHG Emissions

In order to reduce GHG emissions, Astellas must implement initiatives across the entire Group from a medium-term perspective. Based on an understanding of regional differences of customs and practices, Astellas’ manufacturing plants, research centers, sales and marketing divisions, and offices are implementing a variety of initiatives with the aim of mitigating climate change. Regarding tangible elements, efforts to improve facilities, which include the introduction of high-efficiency equipment and the conversion to alternative fuels, are expected to make a significant contribution to reducing the level of GHG emissions generated by energy sources. Regarding intangible aspects, employees’ participation in energy saving through improvements of daily work is also important. To this end, each facility adopts a two-pronged approach, comprising measures related to both tangible and intangible elements.

Promotion Framework and Initiatives for Climate Change Mitigation Measures

Astellas has established the Global EHS Sub-Committee as a special task force under the CSR Committee to discuss measures to deal with various environmental issues, including climate change mitigation measures. Members from regional bases participate in discussions on methods to save energy and reduce GHG emissions throughout the Group based on an analysis of the risks and opportunities that climate change presents to our business, and so forth.
Matters discussed and decided by the Global EHS Sub-Committee will be reported to top management in the CSR Committee.

Analysis of the Risks and Opportunities That Climate Change Presents to Our Business

We carry out scenario analysis regarding changes in the external environment due to such factors as international policy trends and emissions trading systems, the impact on work operations of physical changes caused by climate change, and assessments by stakeholders concerning our measures to mitigate and adapt to climate change. We believe that understanding the conceivable risks and moving forward with medium- to long-term measures to minimize risk will lead to opportunities for our business to be sustainable.

Investment Plan for Climate Change Mitigation Measures

In fiscal 2017, Astellas planned to invest approximately ¥450 million in mainly energy-saving measures at each business facility, the renewal of air conditioning equipment, and the introduction of LED lighting. In fact, we completed an investment of ¥180 million and reduced GHG emissions by 2,061 tons.
Regarding the survey about the possibility of installing a biomass boiler conducted in fiscal 2016, we will continue to investigate its installation despite issues such as cost-effectiveness.

Understanding GHG Emissions in the Value Chain

Although the Environmental Action Plan concerning climate change is targeting emissions directly generated by business activities (Scope 1 and Scope 2), Astellas is also striving to assess emissions produced throughout the entire value chain (Scope 3). We have also set SBTs for GHG emissions from major categories within Scope 3, and are striving to reduce them.
Details of Scope 3 are available in the section on indirect GHG emissions (Scope 3).

Priority Use of Gaseous Fuel

At Astellas’ research and production bases, we use boilers fueled by city gas, LPG and LNG (liquefied natural gas), all of which generate low GHG emissions during combustion. These boilers not only contribute to reducing GHG emissions but also to reducing SOx emissions, another air pollutant.

Introduction of Energy Monitoring Systems

Knowing exactly how much energy we use is useful for the formulation of new strategies. We have introduced energy monitoring systems that can visually monitor energy usage at our facilities.

Reduction of GHG Emissions Generated by Sales Activities magnifying_glass_s.png

Since fiscal 2008, Astellas has been striving to reduce GHG emissions associated with the use of sales fleets. In each region, we are continuously switching over to vehicles with low environmental impact (e.g. hybrid cars). In Japan, where the rate of introducing hybrid vehicles is high, the volume of GHG emissions relative to the number of vehicles has been reduced more than in other regions.
GHG emissions associated with the use of sales fleets are reported under Scope 1.

Changes in GHG Emissions Volume


  Fiscal 2015 Fiscal 2016 Fiscal 2017
Total for each region 28,725 27,287 24,203
Japan 5,276 4,733 4,316
Americas 12,199 10,782 10,760
EMEA 11,250 11,772 9,127

When it is not possible to grasp the actual fuel usage, it is estmiated from mileage and fuel efficiency (catalog value).


Using Renewable Energy magnifying_glass_s.png

The use of renewable energy is one of the most effective climate change countermeasures. Astellas is proactively introducing photovoltaic panels and wind power, and such equipment as biomass boilers, to its facilities. All energy generated through these means is consumed at these facilities.
Moreover, we purchase carbon-neutral city gas and electricity generated by renewable energy sources. As a result, we are indirectly suppressing GHG emissions.

Participation in the Federation of Economic Organizations’ Commitment to a Low-Carbon Society 

Astellas is participating in the commitment to a low-carbon society* formulated by the Federation of Pharmaceutical Manufacturers’ Associations of Japan, which is based on requests from the Federation of Economic Organizations.

*To reduce the amount of carbon dioxide emissions from pharmaceutical manufacturers in fiscal 2020 by 23% based on the amount of emissions in fiscal 2005.
