By engaging with stakeholders and reporting on our sustainability approach and initiatives, we aim to be transparent and open about our sustainability performance and achievements. Sustainability ratings and industry benchmarks provide an important opportunity for us to improve our sustainability performance over time.
In 2018 we engaged professional services firm Deloitte Touche Tohmatsu (Deloitte) to work with us to enhance the rigour behind our sustainability reporting. Deloitte conducted independent limited assurance of our global greenhouse gas (GHG) emissions reporting, selected workforce‑related metrics and the total number of Premiums4Good impact investments and associated financial value for the year ended 31 December 2018. The limited assurance statement is available at the end of this Report.
In 2019 we will continue to expand the scope of our assurance over sustainability‑related metrics.
