Climate change

We recognize that the Otsuka group, which conducts business on a global scale, faces significant risks from the impact of climate change. Accordingly, we are formulating long-term reduction targets and action plans for achieving those targets. Moreover, in aiming to realize a carbon-free society, we promote thorough energy-saving measures and endeavor to alleviate our impact on the environment with the use of renewable energy.

Initiatives for energy use optimization and CO2 reduction

Total CO2 emissionsIn Tokushima Prefecture where the production sites of the group are concentrated, Otsuka Chemical and Otsuka Pharmaceutical Factory supply electricity and steam to neighboring group companies with the use of cogeneration systems they installed. Initiatives overseas to promote efficient energy use and reduce CO2 emissions across the group include the use of the Joint Crediting Mechanism (JCM)* and the installation of highly efficient equipment at P.T. Otsuka Indonesia.

* A system to work with developing countries for reducing greenhouse gas emissions, in which the result of reduction is assessed as contribution by both partner countries and Japan

Third-party verification of GHG emissions

In order to improve the transparency and reliability of its environmental data, the Otsuka group is subject to the verification of greenhouse gas (GHG) emissions (Scopes 1 and 2, and categories 1, 2 and 11 of Scope 3)*1 by third-party organization. We also implement initiatives aimed at understanding and improving the trends in our emissions. We will continue to expand the scope of verification and further enhance the reliability of our data.

*1 Scope 1: Direct emissions
    Scope 2: Indirect emissions from energy sources
    Scope 3: Other indirect emissions

Greenhouse gas emissions throughout the value chain

GHG emissions throughout the value chain in fiscal 2018In order to realize a decarbonized society, it is necessary to determine not just how much CO2 is being emitted directly at our factories, but also the amount of emissions across the entire value chain, from the procurement of materials to their disposal, and then to make efforts to reduce them. The Otsuka group of companies will calculate CO2 emissions for the entire value chain of the five domestic companies, identify the main categories of emissions, and hold discussions on how to reduce them.
