The Sustainability Materiality Mapper

Help me work out which sustainability issues actually matter for this
business — strategically and to stakeholders.

The business and sector: [DESCRIBE]
Stakeholders who care: [INVESTORS, CUSTOMERS, EMPLOYEES, REGULATORS,
COMMUNITY]

Provide:
1. The environmental and social issues most relevant to my sector
2. A double-materiality view: which issues affect the business's value
   (financial materiality) and which reflect the business's impact on the
   world (impact materiality)
3. Where acting on an issue also protects or creates value
4. The few issues worth prioritising and building strategy and reporting
   around
5. The issues that are noise for us versus genuinely material

Focus me on the material few, not a generic ESG checklist. See Section 9
on strategy and this section's ESG prompts.
