Climate Action

GHG reduction targets and actions

HORIBA regards actions for climate change as one of the most important issues in our business.

HORIBA launched a new Mid-Long Term Management Plan “MLMAP2028.” In this plan, we have set a reduction target of carbon neutrality by 2050, with a milestone of 42% reduction of Scope 1, 2 GHG emissions from 2023 to 2033. HORIBA is going to introduce renewable energy as well as save energy at each global site. We will also reduce Scope 3 emissions.

Scope 1, 2 GHG emissions calculation

As part of MLMAP2028, we aim to reduce GHG emissions by 22,839 t-CO₂e, which is equivalent to 42% of the 54,378 t-CO₂e emitted in 2023, leading GHG emissions to be 31,539 t-CO₂e by 2033.

We have discovered that some of the GHG emissions data for 2023 was incorrect and revised the Scope 1 and 2 emissions to 57,742 t-CO₂e. The interim GHG emissions target remains at 31,539 t-CO₂e. which increases the GHG reduction target to 26,203 t-CO₂e, despite this increase, HORIBA will continue to endeavour to achieve carbon neutrality.

Scope 3 GHG emissions calculation

HORIBA Group has been working on the calculation of Scope 3 GHG emissions in accordance with the GHG Protocol. After calculation of Scope 3 GHG emissions in 2024 , the boundary will be expanded to include all Group companies around the world.

We are currently applying for SBT accreditation and our calculations for 2025 are based on the SBT criteria. The results of the SBT accreditation review may lead to adjustments. Based on these aggregation results, we will set Scope 3 reduction targets and further promote activities toward carbon neutrality.
