ESG PROGRESS AT MARRIOTT INTERNATIONAL → 85 2021 SERVE 360 REPORT Assurance Statement Page 1 of 3 LR Independent Assurance Statement Relating to Marriott International , Inc. GHG Emissions and Environmental Data for the Calendar Year 2020 This Assurance Statement has been prepared for Marriott International Inc. in accordance with our contract. Terms of Engagement Lloyd’s Register Quality Assurance , Inc. (LR) was commissioned by Marriott International Inc. ( Marriott ) to provide independent assurance of its greenhouse gas (GHG) emissions inventory and Environmental Data (“the Report”) for calendar year (CY) 2020 against the assurance criteria below to a limited level of assurance and at the materiality of the professional judgement of the verifier using LR’s verification procedure and ISO 14064 - Part 3 for GHG data. Our assurance engagement covered Marriott ’s global operations and activities using the operational control reporting method and specifically the following requirements: • Verifying c onformance with: o Marriott ’s reporting methodologies for the selected datasets; and o World Resources Institute/World Business Council for Sustainable Development Greenhouse Gas Protocol: A corporate accounting and reporting standard, revised edition (otherwise referred to as the WRI/WBCSD GHG Protocol) for the GHG data 1 . • Reviewing whether the Report has taken account of: o GHG Protocol: Corporate Value Chain (Scope 3) Accounting and Reporting Standard. • Evaluating the accuracy and reliability of data and information for only the selected indicator s listed below: o Direct (Scope 1), Energy Indirect (Scope 2) and Other Indirect (Scope 3) GHG emissions; ▪ Scope 3 GHG emissions verified by LR only include franchised properties; o Energy Use and Water Use ; and o Environmental Performance Indicators including: GHG emissions intensity (kg CO2e / square meter), Water intensity (cubic meters / occupied room), and Energy intensity (kWh/ square meter of conditioned space). The Report includes Energy u se and GHG emissions for both global managed and franch ise properties. The Report includes water use and environmental performance indicators for global managed properties only . LR ’s responsibility is only to Marriott . LR disclaims any liability or responsibility to others as explained in the end footnote. Marriott ’s responsibility is for collecting, aggregating, analysing, and presenting all the data and information within the Report and for maintaining effective internal controls over the systems from which the Report is derived. Ultimately, the Report has been approved by, and remains the responsibility of Marriott. LR’s Opinion Based on LR ’s approach , except for the effect of the matters described in the Basis for Qualified Opinion, nothing has come to our attention that would cause us to believe that Marriott has not, in all material respects: • Met the requirements of the criteria listed above; and • Disclosed accurate and reliable performance data and information as summarized in Table 1 and Table 2 below. The opinion expressed is formed on the basis of a limited level of assurance 2 and at the materiality of the professional judgement of the verifier. 1 http://www.ghgprotocol.org/ 2 The 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, t he level of assurance obtained in a limited assurance eng agement is lower than the assurance that would have been obtained had a reasonable assurance engagement been performed. Page 2 of 3 Basis for Qualified Opinion Marriott did not fully address the following issues identified during verification activities: • The calculated emissions for some sources were not consistent with the activity data , stated emission factors and GWP values . These inconsistencies were not material. • Supporting documentation for some renewable energy sources and energy consumption at some hotels was not available during the verification activities. The lack of this suppor ting documentation is not material. • The total conditioned space and total room values used to calculate the energy , water and GHG emissions intensity metrics did not include all of the properties. This does not have a material impact on the intensity values. • The total property counts included in the CY2020 did not include all the properties as per the 10 -K report. This does not have a material impact. Table 1.
