Credibility comes from transparency, facts, and real actions:
- Be specific & quantify: “Low‑flow fixtures reduced water use per guest night by 22% in 2024.”
- Provide third‑party proof: Link to GOTS or FSC certificates.
- Report holistically: Include challenges in ESG report.
- Act first, market later: Measure results for six months before promoting.
- Explain the “why”: Share benefits, e.g., heat recovery saves 50,000 kWh/year.
