Which aspect is NOT typically included in Starbucks' sustainability reports?

Financial performance metrics are not typically included in Starbucks' sustainability reports. These reports focus primarily on the company's environmental and social initiatives, such as environmental impact assessments, social impact initiatives, and supply chain transparency. The purpose of sustainability reports is to provide stakeholders with insights into how the company addresses environmental concerns and contributes to social responsibility, rather than detailing the company's overall financial performance.

Including financial performance metrics would shift the focus away from sustainability efforts and the impact of these initiatives, which is the primary purpose of such reports. Hence, the absence of financial metrics aligns with the overall objective of emphasizing sustainable practices and their effectiveness rather than the financial outcomes of those practices.
