We take a three-stage approach to identifying material sustainability issues to report against — those of most interest to our stakeholders and those where we have the most significant impact.
- Identification. We conduct an annual review of a long list of topics based on analysis of external standards and interest.
- Prioritisation. We score and prioritise topics based on how often they are raised by stakeholders and their level of economic, environmental and social impact — seeking input from internal and external stakeholders.
- Review. We regularly review and refresh our materiality matrix with key stakeholders, considering emerging challenges while remaining focused on delivering our sustainability strategy.
Material Issues 2019
We conducted a full re-assessment of our materiality matrix in 2019. This largely confirmed our previous materiality framework, but resulted in some updates to the long list of issues and thematic clusters:
- Our annual stakeholder survey confirmed our current materiality matrix, although results showed that many of our stakeholders are unaware of relevant disclosures around climate impacts and strategies. We responded by raising the score for “frequency raised by stakeholders” on climate.
- We also raised the score of packaging, for both frequency and impact - based on an evaluation of stakeholder consultations, media coverage, our commitment to the Ellen MacArthur Foundation’s “New Plastic Economy Commitment”, and quickly advancing internal strategies on packaging.
- We saw slightly increased interest in biodiversity from internal and external stakeholders, which is reflected in our updated materiality matrix.
We made some minor adjustments to sub-topics included in our materiality matrix and therefore in this report. For example, we added responsible purchasing practices to our Fair Living Wage strategy and, in response to stakeholder feedback, we added a separate section on supply chain management.
