Independent assurance and review is important to us in helping stakeholders maintain trust in our processes and in what we report, and supports our commitment to openness and transparency.
In 2018, we continued to engage PricewaterhouseCoopers LLP (PwC) to provide limited assurance of selected sustainability data. A summary of recommendations can be found in the Independent Assurance Statement.
We define our approach to reporting within our Reporting Criteria Document, which details the scope, boundaries and assurance status for each of the indicators we report on.
Our environmental performance is reported one year in arrears to allow for data collection, validation and external assurance and is measured against the amount of tobacco net-revenue we generate.
