Emissions Verification

We calculate greenhouse gas (GHG) emissions using the GHG Protocol, which aligns with the Science-Based Target initiative (SBTi) framework, and we obtain third-party verification of our GHG emissions on an annual basis.

GHG emissions data for 2025 were verified by ETSverification – Scopes 1 and 2 at a reasonable level of assurance and Scope 3 at a limited level of assurance.

Emissions in 2023 and 2024, as disclosed in our previous reports, were verified by Dillon Consulting – similarly, Scopes 1 and 2 at a reasonable level of assurance and Scope 3 at a limited level of assurance.
