Welcome to Stone Associates
Stone Associates is a specialist E&S and Sustainability advisory practice. We work with capital investors including development finance institutions, infrastructure investors, and private equity firms on the transactions and portfolios where rigour, independence, and deep technical expertise are non-negotiable - across global markets, and at every stage of the investment lifecycle.
Key Offerings
Sustainability Strategy
Clarity on what sustainability means for your portfolio
We help investors and operators move beyond compliance to build sustainability frameworks that reflect genuine risk, unlock value, and satisfy the expectations of the most demanding institutional counterparties - from DFIs to global PE houses.
Climate Risk
Cutting through complexity to protect what matters
Physical climate risk is now a defining variable in infrastructure investment, asset valuation, and portfolio management. We help investors and asset owners move beyond risk scoring to active adaptation - embedding climate resilience into due diligence, operational decision-making, and capital allocation across climate-exposed assets and markets.
Due Diligence
Rigorous, independent, and built for high-stakes decisions
Our E&S and ESG due diligence is designed for investors who need more than a checklist. We apply IFC Performance Standards, EU Taxonomy, and sector-specific frameworks to surface real risks - and give you the confidence to act on them.
Implementation and Integration
Turning findings into lasting improvement
Effective E&S management doesn't end at due diligence. We support investors, lenders, and project sponsors through the full implementation lifecycle - from ESIA and the development of ESMS and ESMPs, through to Action Plan development, compliance monitoring, capacity building, and ongoing supervision.
Global Reach
Stone Associates has advised some of the world's most demanding institutional investors across four continents. Our client base spans leading development finance institutions and multilateral lenders, global and European private equity firms, independent infrastructure investors, and project sponsors across Sub-Saharan Africa, MENA, Central and Eastern Europe, and Southeast Asia.
