Verification Opinion
London Stock Exchange Group plc CY2023 GHGInventory
Background
Cameron-Cole, LLC (Cameron-Cole) was retained by London Stock Exchange Group plc (LSEG) to perform an
independent verification of its Greenhouse Gas (GHG) Emissions Inventory (GHG Statement) for Calendar
Year (CY) 2023. The Scope 1 and 2 GHG Inventory was developed according to the World Resources Institute(WRI)/World Business Council for Sustainable Development (WBCSD) Greenhouse Gas Protocol: A Corporate
Accounting and Reporting Standard (2004 revised edition) along with its associated amendments. The Scope
3 GHG Inventory was prepared using the WRI/WBCSD Corporate Value Chain (Scope 3) Accounting andReporting Standard dated September 2011 and associated amendments. Our opinion on the results of theinventory, with respect to the verification objectives and criteria, is provided in this statement.

Responsibility of LSEG & Independence of Verification Provider
LSEG has sole responsibility for the content of its GHG Statement. Cameron-Cole accepts no responsibility for
any changes that may have occurred to the GHG emissions results since they were submitted to us for review.
Based on internationally accepted norms for impartiality, we believe our review represents an independent
assessment of LSEG’s CY2023 GHG Emissions Inventory. Finally, the opinion expressed in this verification
statement should not be relied upon as the basis for any financial or investment decisions.

Level of Assurance
The level of assurance is used to determine the depth of detail that a Verification Body designs into theVerification Plan to determine if there are material errors, omissions, or misstatements in a company's GHG
assertions. Two levels of assurance are generally recognized—reasonable and limited. Reasonable Assurance
generates the highest level of confidence that an emissions report is materially correct (with the exception ofAbsolute Assurance which is generally impractical for companies to achieve). Limited Assurance provides lessconfidence and involves a less-detailed examination of GHG data and supporting documentation. Limited
Assurance statements assert that there is no evidence that an emissions report is not materially correct.
Cameron-Cole’s verification of LSEG’s GHG Emissions or Inventory for CY2023 was constructed to provide aLimited Level of Assurance.
