• Drive ESG reviews: Conduct regular ESG assessments and reviews with asset managers and service providers, identifying risks, gaps, and areas for improvement.
• Measure and manage carbon: Support Scope 1, 2 and 3 emissions measurement, including data gathering and the application of carbon accounting methodologies.
• Track regulation: Keep current with ESG regulation, ensuring our processes meet evolving expectations.
• Support impact initiatives: Collaborate with asset teams and stakeholders on biodiversity, community and circular economy projects.
• Tell compelling stories: Translate raw ESG data into case studies and insights that engage investors and demonstrate the value of our ESG work.

What You’ll Need
