Otsuka Holdings Submits Commitment Letter to Obtain Science-Based Targets Validation for the Entire Otsuka Group
January 14, 2026
Otsuka Holdings Co., Ltd. (Head Office: Chiyoda-ku, Tokyo, Japan; President and Representative Director, CEO: Makoto Inoue) has submitted a Commitment Letter to the Science Based Targets initiative (SBTi)※1 to obtain validation for science-based targets across the entire Otsuka group※2.
SBT refers to greenhouse gas (GHG) emission reduction targets that companies set in line with the level required under the Paris Agreement and based on scientific evidence. A Commitment Letter signifies a company’s pledge to set targets aligned with SBT standards and apply to SBTi within two years.
Until now, individual companies within the Otsuka group have obtained science-based targets validation separately. This time, the group aims to obtain validation for the group as a whole.
The Otsuka group has established the 2050 Environmental Vision “Net Zero“ which aims to reduce the total environmental impact of the group’s business activities to zero. The group has identified issues such as carbon neutrality and water neutrality as key environmental initiatives and is working collaboratively across the group to achieve these goals.
With respect to carbon neutrality, the group is utilizing renewable energy by installing mega solar power systems and introducing CO2-free electricity, and improving energy use efficiency by introducing cogeneration systems. The Otsuka group will continue to promote group-wide efforts to reduce GHG emissions throughout the business value chain in line with international targets and indicators established under the Paris Agreement to achieve a decarbonized society and, ultimately, a sustainable society.
※1 The Science Based Targets initiative (SBTi) is a corporate climate initiative which was initially founded as a collaboration between CDP, United Nations Global Compact (UNGC), We Mean Business Coalition, World Resources Institute (WRI), and World Wide Fund for Nature (WWF). It validates whether corporate GHG emission reduction targets are consistent with scientific knowledge to achieve the Paris Agreement’s goal of holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels.”
