Our Environmental, Social and Governance (‘ESG’) performance is externally reviewed by various ratings agencies, voluntary disclosure initiatives, auditors, and certifiers.
External opinions of our performance inform how we strengthen our management of ESG risks and opportunities and support us to develop our disclosures in future reporting years.
This is one of the ways in which we evaluate the effectiveness of our Building for a Sustainable World sustainability framework. We explore our approach to Our People, Our Places, and Our Planet across our sustainability pages.
On our certificates and memberships page, you can find more information about our sustainability commitments.
More information about our ESG performance and how we report is available in our annual reporting.
