S11_ From instruments to systems: Evaluating the private sector’s increasing role in development, climate and market transformation

José Carbajo, Miriam Amine
Rationale and Objectives
In a context of declining official development aid and expanding expectations for private capital to deliver development and climate outcomes, private sector actors, corporate sustainability practices, and market based instruments play an increasingly leading role in shaping public value. Development and climate finance institutions now rely extensively on blended finance, guarantees, funds, and advisory instruments to mobilise private investment, manage risk, and catalyse market transformation. At the same time, corporate ESG commitments, impact frameworks, and non-financial support services are growing, often working through private governance systems and proprietary data. While these trends promise scale and innovation, they also raise fundamental questions for evaluation in vibrant democracies around transparency, accountability, equity, and learning when public objectives are pursed through complex public-private arrangements.

This strand addresses these challenges by positioning evaluation as a critical instrument for systemic learning and democratic accountability in increasingly private sector-driven development and climate finance. Led by EES Thematic Working Group 3 (TWG3), the strand aims at advancing evaluation approaches that move beyond project level accountability and descriptive portfolio reviews towards credible assessment of systemic effects, organisational change, and long-term market transformation. It focuses on three interrelated domains: development, finance instruments, and private capital mobilisation; corporate sustainability, ESG, and impact accountability; and market systems, systemic change, and just transitions.

Across these areas, the strand looks to a strengthening evaluation practice, theory, and use by addressing persistent challenges related to additionality, attribution versus contribution, long time horizons, confidentiality, and distributional impacts. By doing so, it aims at repositioning evaluation not only as an exposed accountability mechanism, but as a decision-relevant learning tool that informs institutional strategy, policy dialogue, and public debate, thereby contributing to trust and legitimacy at the public-private interface.
Strand Overview
The strand is organized around three interconnected sessions.

The first session, ‘From Deals to Systems: Evaluating Private Capital Mobilisation and Risk-Taking Instruments’, examines, how evaluation can assess whether blended finance, guarantees, funds, and other risk sharing instruments, genuinely mobilize, private capital and contribute to market transformation. It explores approaches to assessing financial and non-financial additionality, contribution versus attribution, and demonstration effects, emphasizing portfolio- and market-level analysis that integrates financial evidence with qualitative investor perspectives.

The second session ‘From Reporting to Learning: Evaluating ESG and Non-Financial Support Services and the Value Add of Impact Frameworks’, shifts attention to organisational practices and governance systems that shape behavior within financial markets. It examines, how evaluation can engage critically with ESG ratings, impact framework, and technical cooperation as strategic levers of change, comparing proprietary measurement tools with evaluative standards of rigor, causality, and learning. The session addresses challenges related to attribution, long-term horizons, confidentiality, and private governance, and explores suitable evaluation approaches (ranging from theory-based and qualitative methods to emerging AI-supported and foresight techniques) that reposition evaluation as a value-adding input to corporate strategy, risk management, and transition finance rather than a narrow compliance function.

The third session ’Evaluating Market Systems and Just Transitions: Equity, Trade-offs, and Organisational Change’, broadens the perspective to system-level transformation. It focuses on evaluating market systems development, financial inclusion, and climate finance strategies in a context where private capital is expected to play a growing role amid shrinking ODA. The session explores how evaluation can identify trade-offs between efficiency, scale, and equity, assess distribution impact, and examines whether organisations meaningfully integrate just-transition principles to strategies, governance, and decision making processes. Together, the three sessions provide a structured exploration of systemic learning, showing how evaluation can inform strategic decision-making and democratic accountability in vibrant democracies.
