We participate in the Carbon Disclosure Project Climate Change programme to disclose our climate strategy and performance to a collaboration of institutional investors. In 2019, our score dropped to B from A- in 2018, mainly due to our score for governance of climate-related issues and being unable to report on our full scope 3 inventory at the time of reporting. While disappointing, we now have measures in place to help to restore our score. These measures include strengthened governance through our new Board-level Sustainability Committee, and the work on scope 3 emissions described on page 40.
