LRQA Independent Assurance Statement
Relating to Bridgestone Group’s Greenhouse Gas Emissions Inventory,
Environmental and Social Data for the calendar year 2023
This Assurance Statement has been prepared for Bridgestone Corporation in accordance with our contract.

Terms of Engagement
LRQA was commissioned by Bridgestone Corporation (“the Company”) to provide independent assurance on its
greenhouse gas (GHG) emissions inventory, and on its environmental and social data (“the report”) for the calendar
year 2023, that is, from 1 January to 31 December 2023, against the assurance criteria below to a limited level ofassurance at the materiality of the professional judgement of the verifier and using ISAE 3000 (Revised) and ISO 14064- Part 3:2019 for GHG emissions.
Our assurance engagement covered Bridgestone Group’s operations and activities in Japan and overseas andspecifically the following requirements:• Verifying conformance with the Company’s reporting methodologies for the selected datasets:• Evaluating the accuracy and reliability of data for only the selected indicators listed below:
Environmental1• Amount of raw materials used, Ratio of Recycled/Renewable Material• Total energy consumption, Energy consumption (fuels, consumption of fuels oriented from renewableenergy, Energy consumption (purchased electricity, consumption of purchased electricity oriented fromrenewable energy, Energy consumption (purchased steam), Energy consumption (self-generated
renewable electricity from non-fuel sources; solar, etc.), Electricity sold, Total energy consumption(renewable), Total energy consumption (non-renewable),• Total water withdrawal, Total water withdrawal in water stress area, Water withdrawal (surface water),
Water withdrawal (groundwater), Water withdrawal (water supply, industrial water), Water withdrawal(seawater),• GHG emissions 2 (Scope 1), GHG emissions (Scope 2) Market-based and Location-based, GHG emissions(Scope 3) Categories 3 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 14 and 15,• Contribution to CO2 Reduction by reducing rolling resistance, etc. (compared with 2020)4• NOx emissions, SOx emissions,• Volume of waste generated, Volume of recycled waste, Recycling waste rate, Volume of waste to landfill,
Volume of regulated hazardous waste generated, Volume of regulated hazardous waste recycled, Volumeof regulated hazardous waste to landfill,• Product Circularity5,• Resource productivity, and• Sites with ISO14001 certification6

GHG quantification is subject to inherent uncertainty.
Scope 1 and 2 GHG emissions are as defined in The Greenhouse Gas Protocol – A Corporate Accounting and Reporting Standard.
3
The categories of Scope 3 GHG emissions are as defined in the Greenhouse Gas Protocol – Corporate Value Chain (Scope 3) Accounting and ReportingStandard, Table 5.3.
4
Calculated using Bridgestone's calculation method based on the "Tyre LCCO2 Calculation Guidelines Ver. 3.0.1” (The Japan Automobile Tyre
Manufacturers Association, Inc) etc.
5A concept to show circularity of used products. The Group used the ratio of beneficial next use of used tires collected by its shops/stores (based on thenumber of shops/stores and contracts with processing companies) as the indicator for product circularity.
26It covers 98 production sites in Japan and overseas.

Our assurance engagement excluded the data and information of the Company’s suppliers, contractors and any
third-parties mentioned in the report.
LRQA’s responsibility is only to the Company. LRQA disclaims any liability or responsibility to others as explained in
the end footnote. the Company’s responsibility is for collecting, aggregating, analysing and presenting all the dataand information within the Report and for maintaining effective internal controls over the systems from which theReport is derived. Ultimately, the Report has been approved by, and remains the responsibility of the Company.

LRQA’s Opinion
Based on LRQA’s approach nothing has come to our attention that would cause us to believe that the Company has
not, in all material respects:• Met the requirements of the criteria listed above; and• Disclosed accurate and reliable performance data and information on GHG emissions and key environmental
and social data as summarized in Table 1, 2, 3 below.
The opinion expressed is formed on the basis of a limited level of assurance11 and at the materiality of the professional
judgement of the verifier.

It covers 115 production sites in Japan and overseas.

9Occupational health and safety related standards include ISO 45001, VPP-Star and Safe production standardization.

10It covers 106 production sites in Japan and overseas.

11The extent of evidence-gathering for a limited assurance engagement is less than for a reasonable assurance engagement. Limited assurance
engagements focus on aggregated data rather than physically checking source data at sites. Consequently, the level of assurance obtained in alimited assurance engagement is lower than the assurance that would have been obtained had a reasonable assurance engagement been
performed.

LRQA’s Approach
LRQA’s assurance engagements are carried out in accordance with ISAE 3000 (Revised) and ISO 14064-3. The
following tasks were undertaken as part of the evidence gathering process for this assurance engagement:• Auditing the Company’s data management systems to confirm that there were no significant errors, omissions
or misstatements in the report. We did this by reviewing the effectiveness of data handling procedures,instructions and systems, including those for internal verification.
• Interviewing with those key people responsible for compiling the data and drafting the report.
• Sampling datasets and traced activity data back to aggregated levels;• Verifying the historical data and records for the fiscal year 2023; and• Visiting Bilbao factory in Spain to confirm the data collection processes, record management practices, and tophysically check emission sources etc.
• Conducting the remote verification to Monterrey factory in Mexico and Mexico Carbon Manufacturing S.A de C.V
for confirming the effectiveness of its data management systems via emails and Microsoft Teams.

Observations
Further observations and findings, made during the assurance engagement, are:• It is recommended the Company will continue to maintain the high-level data management systems anddiscover further improvement opportunities proactively to ensure accurate aggregation and calculation ofenvironmental and social data.
LRQA’s Standards, Competence and Independence
LRQA implements and maintains a comprehensive management system that meets accreditation requirements for
ISO 14065 Greenhouse gases – Requirements for greenhouse gas validation and verification bodies for use inaccreditation or other forms of recognition and ISO/IEC 17021-1 Conformity assessment – Requirements for bodies
providing audit and certification of management systems – Part1: Requirements that are at least as demanding as
the requirements of the International Standard on Quality Control 1 and comply with the Code of Ethics forProfessional Accountants issued by the International Ethics Standards Board for Accountants.
LRQA ensures the selection of appropriately qualified individuals based on their qualifications, training andexperience. The outcome of all verification and certification assessments is then internally reviewed by senior
management to ensure that the approach applied is rigorous and transparent.
This is the only work undertaken by LRQA for the Company and as such does not compromise our independence orimpartiality.
