[FY2024 Emissions Calculation Parameters and Reporting Standards]
*1 <Scope 1 and 2>
・Boundary：Suzuki Motor Corporation, 68 domestic manufacturing and non-manufacturing subsidiaries and 37 overseas manufacturing and non-manufacturing subsidiaries
・Target gases: Greenhouse gases (seven gases: carbon dioxide, methane, dinitrogen monoxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, nitrogen trifluoride)
・Calculation method: Scope 2, calculated based on the GHG Protocol’s market standards
・Emission coefficients
− Electricity: The latest basic emission factors by electric utility (FY2023 results, published on August 1, 2025) by electricity provider for Japan, and IEA Emissions Factors 2024 for overseas
− Fuel: Emission coefficients under Japan’s Mandatory Greenhouse Gas Accounting and Reporting System (Ver. 5.0) were used in Japan, and IPCC Guidelines 2006 were used overseas. Unit calorific values for city gas are those released by suppliers.

*2 <Scope 3 Category 11>
・Boundary: Suzuki Group
・Products subject to calculation: Automobiles, motorcycles, outboard motors, motorized wheelchairs, and other Suzuki products
・Outline of calculation method
− Calculated by multiplying the estimated lifetime running distance of products sold in the fiscal year under review by the emissions intensity for each model.
− Annual running distance and years of use are based on published information, primarily the IEA SMP Model.
− Emissions intensity for each model is based on the certified values prescribed by the regulations of each country and converted to WTW (Well-to-Wheel).
