Ecosystem conversion and restoration
Diageo provides some evidence of addressing conversion but this does not necessarily mean they follow DCF-aligned practices. They also lack time-bound targets to achieve conversion-free supply chains and do not commit to ensuring zero conversion. Moreover, the company shows no commitment to restoring ecosystems and fails to disclose specific details and outcomes of ecosystem restoration projects in areas impacted by their own operations or by their suppliers.
GHG emissions
Although Diageo reports against its scope 3 target, it shows increase in its scope 3 emissions levels.
Impact and dependencies assessment
Diageo states it tracks its impact on local biodiversity by measuring the proximity of its operational sites to protected areas and high-biodiversity zones. Despite this, it does not disclose the methodology and results for assessing impacts on nature, including biodiversity, within its operations. It has conducted a materiality assessment on deforestation risks in its supply chains using various data sources, and has also carried out a deep-dive impact assessment in Ireland and Northern Ireland following the Science Based Targets for Nature methodology. However, there is no comprehensive disclosure of methodology and results for assessing its impact on nature in its upstream value chain. While the company acknowledges its dependency on agricultural and forest commodities, there is no evidence that it assesses dependencies on nature within its operations or in its upstream business relationships.
Invasive species
Diageo has not identified any activities that could lead to the introduction of invasive alien species in its own operations.
Key areas and species
Diageo has an opportunity to disclose its suppliers’ locations within or adjacent to areas important for biodiversity. It could also disclose existing species populations existing in or adjacent to both its own and its suppliers’ locations.
Resource exploitation and circularity performance
Diageo does not report quantitatively on its group-wide circularity performance. The company has an opportunity to disclose a target to improve soil health in its production or sourcing practices and report progress against it.
Solid and air pollution
Diageo does not disclose relevant information related to pollution in its operations or supply chains.
Water
Diageo has an opportunity to show quantitative reductions in water withdrawal in its own operations. Furthermore, the company has an opportunity to engage with suppliers to improve water withdrawal, and set targets to reduce water pollution.
