LINKS has delivered a step change in how climate finance is analysed by modelling financial systems as complex, evolving networks of heterogeneous actors, rather than as frictionless markets. Using large-scale investment data and network methods, the project established the foundations of the emerging field of climate finance networks, showing how financial structures, investor behaviour, and policy interventions jointly shape low-carbon investment outcomes.
In its first phase, LINKS mapped global co-investment networks across low-carbon technologies, countries, and time. This work showed that investment is organised through highly structured and unequal networks, where a limited number of actors exert disproportionate influence over deployment pathways. The analyses identified early movers, scale-up enablers, and the distinct roles of local and international investors across regions and technologies.
LINKS then examined network evolution over two decades of investment data. A key result is the identification of strong path dependency: once investment patterns are established, they tend to reinforce themselves - accelerating deployment in some contexts while systematically excluding others. At the same time, the project demonstrated the existence of positive financial tipping points, whereby small changes in expectations, coordination, or policy signals can trigger non-linear increases in low-carbon investment once key thresholds are crossed.
The final phase of LINKS focused explicitly on the investment challenge in developing and emerging economies. Building on earlier work on cost-of-capital disparities, LINKS showed that the main barrier is often no longer technology cost, but perceived and interacting investment risks embedded in global financial networks. Empirical analyses demonstrated how suitability criteria, risk perceptions, and investor learning perpetuate unequal mitigation finance flows and reinforce cross-country disparities.
LINKS further showed that policy effectiveness depends critically on financial network structures. Disclosure initiatives alone are insufficient to shift capital unless they interact with underlying market architectures. A major study on banking finance demonstrated why fossil fuel lending remains resilient even under phase-out commitments, due to syndicated lending structures that dilute unilateral withdrawals. Phase-out accelerates only when regulatory stringency reaches a systemic tipping point, particularly when large banks lead.
Sectoral analyses highlighted additional dynamics, including evidence that banks increasingly price climate performance at the corporate rather than asset level, and that rapid renewable energy scale-up can generate social trade-offs if financial flows are poorly governed.
