Rohto Pharmaceutical (Group) considers addressing climate change to be a top priority in order to achieve carbon neutrality by 2050, aiming for net-zero greenhouse gas emissions. Recognizing that reducing greenhouse gases (GHGs) is a challenge for society as a whole, we have undertaken various initiatives to conserve energy in offices and factories, and to reduce the environmental impact of transportation and other activities. Regarding CO2 emissions, we have revised our targets and are working towards a goal of reducing Scope 1 and 2 emissions by 46% compared to FY2013 by 2030. In FY2025, we achieved a 41% reduction compared to FY2013, reaching our interim target of a 30% reduction. We will continue to actively work to reduce greenhouse gas emissions from our business activities and mitigate global warming.
Setting goals
- Reduce total Scope 1 and 2 CO2 emissions by 46% by fiscal 2030 compared to fiscal 2013
- The intermediate goal is to reduce emissions by 30% by fiscal 2025 compared to fiscal 2013.
Towards Scope 1 and 2 reduction
We are promoting activities aimed at reducing Scope 1 and 2 CO2 emissions by 46% by 2030 compared to fiscal 2013.
Our Initiatives
Initiatives at Plants
We have introduced a cogeneration system to reduce the amount of electricity purchased during peak demand and to effectively utilize waste heat for heating and cooling. In addition, in the new factory building, we have introduced a geothermal heat pump system that is not affected by the amount of sunlight or weather, and are using it to reduce the air conditioning load. We are promoting the electrification of energy in the factory and the shift to renewable energy by switching purchased electricity to electricity generated from renewable energy sources (CO2-free menu). In fiscal year 2024, we further electrified by replacing gas-fired hot water boilers with heat pump water heaters, and then in fiscal year 2025, we switched 84.1% of the electricity purchased in the factory and research institute to CO2-free electricity. We aim to achieve 100% conversion by 2030.
We are also making progress in introducing solar power generation. In fiscal year 2024, our third solar power generation facility began operation at our Ueno Plant, which is our main factory. We are also progressively introducing solar power generation facilities at the factories of our group companies both domestically and internationally.
Initiatives in logistics
Our products are mainly pharmaceuticals and cosmetics, so they are relatively small in size, and each delivery tends to be a small, diverse mix. However, we are working to improve delivery efficiency by consolidating deliveries and ordering by pallet level. We are also working with our business partners to achieve a modal shift, which has led to a reduction in CO2 emissions. We will continue to work with our business partners to improve efficiency and strive to be environmentally conscious.
Modal shift
Together with our agents, we are promoting a modal shift from land transport (trucks) to more efficient marine transport (ferries), starting with deliveries to the Kyushu region. This initiative is helping to address the driver shortage, improving the working environment for drivers involved in long-distance transport, and contributing to the reduction of CO2 emissions.
Joint delivery (shipper collaboration)
In response to challenges in the logistics industry, such as labor shortages and long working hours for drivers, we have partnered with Milbon Co., Ltd., Haleon Japan Co., Ltd., and Toyo Warehouse Co., Ltd. to begin joint deliveries in August 2025, which combine common products on delivery routes. Taking into account constraints such as pallet size, transport volume, and product safety, we select products suitable for joint delivery, verify loading techniques, and conduct quality tests, and aim to maximize transport efficiency by connecting manufacturing bases and warehouses using a relay system. We will contribute to building a sustainable supply chain by reducing CO2 emissions and driver workloads.
[Award] This initiative won the category award (director-general level award) "Logistics Structural Reform Award" jointly with the four companies at the "2025 Logistics Partnership Excellent Business Awards" sponsored by the Ministry of Land, Infrastructure, Transport and Tourism and the Ministry of Economy, Trade and Industry (award presented on December 23, 2025, announcement on December 24).
Reduced delivery frequency
We aim to build a sustainable delivery system that increases logistics efficiency while reducing environmental impact and transportation costs. By utilizing the overhead space of trailers and improving loading efficiency from 65% to a maximum of 95%, we have been able to reduce the number of trailers transporting products from factories to the Kanto warehouse from four to three per day. We will continue to work on improving efficiency and efficiency.
Improved loading efficiency
Aiming to maximize the use of pallet area for loading, we are promoting improvement activities such as optimizing pallet usage. Comparing 2021 and 2024, the utilization rate of loading in which pallet area is fully utilized (pallet area utilization rate of 80% or more) increased by 8 points.
研究所での取り組み
当社研究所（本社理化学試験室、本社微生物試験室）では、研究・試験環境における環境負荷の低減に取り組んでいます。その取り組みの一環として、研究所の環境パフォーマンス改善に焦点を当てた国際的な認証プログラム「My Green Lab」に参加しています。
My Green Lab認証では、エネルギー効率、水資源の保全、廃棄物の削減、化学物質の管理、責任ある調達、資源管理、組織全体における環境配慮の文化（グリーンカルチャー）など、研究活動に関わる幅広い観点から取り組みが評価されます。
当研究所は、2024年にMy Green Lab Certification 1.0において最高ランクである「Green」を取得し、2026年には新たなCertification 2.0による再認証を受け、継続して「Green」認証を取得しています。
My Green LabのImpact Estimatorによる試算では、この取り組みにより、年間でエネルギー使用量160,632kWh、水使用量0.65MLの削減、CO2排出量79tCO2eの削減、約630万円のコスト削減が見込まれています。※
今後も、持続可能な研究環境づくりに向けた改善を継続し、「科学的イノベーション」と「環境への責任」がともに前進する研究環境を目指し、環境負荷のさらなる低減に取り組んでいきます。

Initiatives at Offices
We have introduced casual Fridays every Friday and Cool Biz in the summer, and are working to save energy in the office and reduce CO2 emissions.
Efforts Related to Sales Activities
At our company, our sales representatives use company vehicles for purposes such as visiting clients. In order to reduce CO2 emissions from company vehicles, we are reducing the number of vehicles themselves and switching to hybrid vehicles and other vehicles that have a lower environmental impact. We began introducing hybrid vehicles in 2003, and currently all company vehicles have been switched to hybrid vehicles, contributing to a reduction in CO2 emissions.
