What matters most?: How boards can use materiality to prioritise sustainability

In an increasingly complex business landscape, it is crucial that sustainability initiatives are strategically aligned with core business priorities to drive action. This deep dive explores how boards can focus on materiality (i.e. matters of business significance) to support effective board-level decision-making, drive efficiencies and enhance resilience.
Testimonial

Our primary focus as an ESG & Ethics Committee is to translate the evolving ESG agenda into practical, actionable transition plans that are measurable, benchmarked, and aligned with clear milestones. Achieving this requires a disciplined scan of the ESG universe and the application of materiality to identify the areas that matter most, thereby enabling effective resource allocation, planning, and programme implementation. In our case, the most material issue is Scope 3, specifically the financed GHG emissions of our lending portfolio. We have assessed our total contributed emissions, identified the industries with the greatest contribution, and put forward a targeted programme to drive emissions reductions through green lending initiatives and client awareness-building.

For many years, organisations have increasingly used the concept of materiality to understand what sustainability matters are most relevant to their investors and broader stakeholders, and subsequently use this understanding to drive strategic decisions.

An organisation’s ability to generate value over time is linked to its interactions with stakeholders, society, the economy and the natural environment. However, an organisation is likely to also impact the environment and people in a range of ways, including through its value chain. Understanding these impacts is essential for organisations to determine material drivers of value and risk. If undertaken strategically, a comprehensive materiality assessment will explore how all these sustainability issues are likely to affect the future resilience and success of the business.

The materials below are designed to support board members in ensuring that materiality assessments are harnessed as a strategic decision-making tool:
