Today, we proudly manage over £7bn in renewable energy assets worldwide.

Our dynamic portfolio includes over three hundred major energy-generating companies, from wind farms to solar power plants, with exciting new ventures in energy storage and hydrogen on the horizon. As we continue to grow, we’re looking for passionate individuals to join our diverse and dedicated team, helping us drive the future of renewable energy forward.

7. Measure and manage carbon: Support Scope 1, 2 and 3 emissions measurement, including data gathering and the application of carbon accounting methodologies.
8. Track regulation: Keep current with ESG regulation, including SFDR, EU Taxonomy, TCFD and CSRD, ensuring our processes meet evolving expectations.
9. Support impact initiatives: Collaborate with asset teams and stakeholders on biodiversity, community and circular economy projects.
10. Tell compelling stories: Translate raw ESG data into case studies and insights that engage investors and demonstrate the value of our ESG work.
