External commentary & assurance
Here we share external views on our strategy and reporting.
An external view
Our strategy and reporting is strengthened by the feedback we get from our stakeholders. This year we have again asked the external experts that make up the Unilever Sustainable Development Group for their views on our progress to date.
Internal and external assurance is also an important part of our approach.
