OMRON Group’s Scope 1, 2, and 3 GHG Emissions

OMRON Group’s Scope 1, 2, and 3 GHG Emissions (FY2023)

To assess the environmental impact of the Group's business activities as a whole, including its value chain, the OMRON Group in fiscal 2013 began calculating Scope 1, 2, and 3 of the OMRON Group's greenhouse gas (GHG) emissions. The calculation is based on the GHG Protocol, which is the most widely used international accounting and reporting tool.

CO2 emission factors used for the calculation of CO2 emissions

Starting in fiscal 2016, OMRON has been using the following publicized CO2 emission factors for electricity:
Japan: Emissions factors set for each power company for calculating, reporting, and publishing greenhouse gas emissions based on the Act on Promotion of Global Warming Countermeasures (by category or residual)
China: Emission factors set forth for each power company by the National Development and Reform Commission;
Other countries: Country-specific emission factors set forth by the International Energy Agency (IEA, 2020).

For emission factors for fuels, the OMRON Group uses factors set in the "Manual for Calculating and Reporting Greenhouse Gas Emissions" of the System to Set, Report, and Publish Greenhouse Gas Emissions based on the Act on Promotion of Global Warming Countermeasures.

Independent Assurance of GHG Emissions

To ensure the reliability of its data, the OMRON Group’s GHG emissions data (Scope 1, 2, and 3) underwent third-party review by Bureau Veritas Japan Co., Ltd. The Group received a report that verified appropriate measurement, calculation, and reporting of GHG data, including source data, or evidence.

Category Verification source data (evidence) Verification standard
Scope 1 and 2 -Purchased volume on invoices: Electricity and gas (city gas, LPG, and LNG)
-Consumption volume of fossil fuels managed by internal systems, such as heavy fuel oil and heating oil		 International Standard on Assurance Engagements (ISAE) 3000 (Revised), Assurance Engagements Other than Audits or Reviews of Historical Financial Information
(Effective for assurance reports dated on or after December 15, 2015)
ISO14064- 3(2006): Greenhouse gases Part 3: Specification with guidance for the validation and verification of greenhouse gas assertions
Scope 3 -Activity data of category elements managed by internal systems
-Emission factors by activity datum
