Transparency frameworks such as the Global Reporting Initiative (GRI) are increasingly cited in tender processes. For buyers in developing markets, partnering with certified suppliers not only supports responsible growth but also opens access to premium export markets.
Supplier sustainability scorecards and annual ESG audits are becoming common in procurement contracts. Buyers should insist upon clear reporting on energy usage, emissions, use of recycled/recyclable materials, and waste management protocols. This is particularly vital for projects backed by international lenders or destined for multinational OEMs, where downstream supply chain accountability is enforced.
Action Points for International Buyers:
- Source from suppliers with verified green credentials (ISO, GRI, or “green steel” certifications).
- Incorporate sustainability clauses and KPIs in procurement contracts.
- Request documentation and proof of ethical practices throughout the supply chain.
- Engage in supplier development programs to elevate ESG standards among regional partners.
