ROHM Revises Its Greenhouse Gas Emission Reduction Targets for 2030 to Achieve a Decarbonized Society

Includes support for the recommendations of the Task Force on Climate-related Financial Disclosures

Willich-Münchheide, Germany, September 30, 2021 – ROHM has recently revised its medium-term environmental targets for 2030 with the aim of achieving a carbon-free society. At the same time, we have agreed to endorse the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and work on information disclosure in line with these recommendations. Recognizing that climate change is one of the most important issues affecting our business activities, ROHM has set a goal of achieving zero carbon (virtually zero greenhouse gas emissions) by 2050 in its “Environmental Vision 2050” enacted in April 2021. Subsequently, in our medium-term management plan “MOVING FORWARD to 2025”, we announced our mid-term environmental targets for the period up to 2030 and have been promoting initiatives to reduce greenhouse gas emissions, such as accelerating the introduction of renewable energy. As the risks related to climate change become more apparent, we will further raise our greenhouse gas reduction targets by 2030 and promote efforts to reduce environmental impact and achieve our “Environmental Vision 2050”. Medium- to Long-Term Environmental Targets To realize virtually zero greenhouse gas emissions by 2050, we revised our greenhouse gas emission reduction target for 2030 from the 30% previous set in 2018 to 50.5%. We have also submitted a commitment letter to obtain Science Based Targets (SBT) certification (given to greenhouse gas emission targets that comply with the Paris Accords), which we will apply to this target. Endorsing TCFD Recommendations ROHM is promoting continuous improvement towards environmental conservation by establishing and operating a group-wide environmental management system in compliance with the ISO14001 international standard. At the same time, we have been making efforts to proactively disclose information by publishing annual targets and initiatives based on our environmental policy and vision along with various ESG data on our website. And going forward, we will carry out scenario analysis in accordance with the TCFD recommendations that we have endorsed while focusing on more transparent information disclosure. ROHM will continue to promote sustainability management in line with our corporate objectives and management vision along with technological innovation in power and analog semiconductors, which are key devices for improving efficiency, while actively engaging in a variety of environmental conservation activities and environmental investments – including not only climate change but also resource recycling and coexistence with nature – in accordance with our newly established environmental vision to achieve a sustainable society. Terminology TCFD (Task Force on Climate-related Financial Disclosure) An organization established by the Financial Stability Board (FSB) for the purpose of disclosing climate-related information and examining how financial institutions should respond. It encourages companies to understand and disclose their governance, strategy, risk management, and indicators/targets related to climate-based risks and opportunities. Paris Accords An international agreement adopted at the 21st Conference of Parties (COP21) by the United Nations Framework Convention on Climate Change (UNFCC) in 2015 to reduce greenhouse gas emissions after 2020. It stipulates that the average global temperature rise should be limited to well below 2°C (preferably 1.5°C) compared to pre-industrial levels. SBT (Science Based Targets) An international initiative that calls for the establishment and implementation of scientific targets consistent with greenhouse gas reduction scenarios to achieve the goals of the Paris Accords.
