Decarbonization Initiatives

Vision and Numerical Target


“Working toward carbon neutrality 2050, we will contribute to the realization of a decarbonized society.”

We are participating in the Carbon Neutral Action Plan for 2050 formulated by the Federation of Pharmaceutical Manufacturers’ Associations of JAPAN (FPMAJ), and have set a medium-term target of reducing CO2 emissions by 46% from the FY2013 level by FY2030.
Currently, by introducing cogeneration systems, eco-friendly vehicles for company vehicles, LED lighting, solar power panels, the introduction of waste heat recovery heat pumps, and other measures, we have successfully reduced emissions volume by 30% from the FY2013 level by FY2021.
Going forward, we will strive to achieve our medium-term target by purchasing CO2-free electricity and introducing solar power generation in the PPA model, thereby contributing to the realization of a decarbonized society that will achieve carbon neutrality by 2050.

Numerical Target

Medium-term target: Reduce CO2 emissions volume by 46% by 2030 from 2013.

Working toward a Carbon-Neutral Society

The Group considers climate change to be one of the most important issues for global environmental conservation, and is working to reduce its greenhouse gas emissions in order to contribute to the prevention of global warming.

Introduction of Cogeneration System

At the Iwaki Factory, we have worked to improve the operational efficiency of the cogeneration (combined heat and power) system and the manufacturing process.

Introduction of Eco-friendly Commercial Vehicles

ASKA Pharmaceutical is promoting the deployment of eco-friendly commercial vehicles.

Purchase of CO₂-free Electricity

In April 2023, the Iwaki Factory introduced CO₂-free electricity for some of its electricity use. This will reduce CO₂ emissions by approximately 530 tons per year. ASKA gradually switches to CO₂-free electricity, which will reduce CO₂ emissions by a total of approximately 2,200 tons

Install of Solar Power Generation under the PPA Method

At the Iwaki Factory, ASKA Pharmaceutical decided to introduce solar power generation under the PPA* method and began preparation for the facilities in order to start supplying electricity. This will reduce CO₂ emissions by approximately 440 tons per year.

* PPA(Power Purchase Agreement)A system that enables companies that own and manage solar power generation equipment (the PPA provider) to install that equipment at sites or roofs provided by facility owners, and those owners (electricity users) purchase the power generated by the solar power generation equipment at a discount.

Introduction of aste Heat Recovery Heat Pumps

ASKA Pharmaceutical has decided to introduce a waste heat recovery heat pump at its Iwaki Factory. Construction has begun and preparations are underway for the introduction of the heat pumps in the air conditioning chiller equipment, which is expected to reduce CO₂ emissions by approximately 422.6 tons per year.  

Energy Conservation Efforts

We aim to improve energy consumption per unit of production by 1% or more each year (The average rate of change in energy consumption per unit of production over the previous five years is 1% or more.) as an indicator of energy consumption. In FY2020, the average rate of change in energy consumption per unit of production over the previous five years was a 3.7% reduction.

Participation in Initiatives

Participation in Renewable Energy 100 Declaration RE Action

Renewable Energy 100 Declaration RE Action is a framework for companies, local governments, educational institutions, medical institutions, and other organizations to demonstrate their will and actions to convert 100% of the electricity they use to renewable energy and promote the use of 100% renewable energy. We joined the framework in March 2024.

Toward a Recycling-Oriented Society

We aim to use resources more efficiently and minimize waste as much as possible, which is crucial for maintaining business continuity. We have set the reduction of waste as a target in our medium-term environmental plan. and are actively working on resource saving and waste reduction measures. To protect the environment and continuously reduce environmental impact in all of our business activities, we are working to reduce energy consumption, promote waste reduction and reuse, and control emissions of air and water pollution, chemical substances, and other pollutants. By proactively addressing resource conservation and waste reduction, we will contribute to the creation of a recycling-oriented society that aims for more efficient use of resources.
