Private capital would finance most of the European Union’s green investment needs under an ECB analysis that estimates extra annual investment equal to about 3% of EU GDP through 2030.
The ECB article estimates public funding at 20% to 25% of total green investment needs. That share applies to the overall total, while the 3% figure measures the additional investment needed each year. The ECB estimates that private capital would need to cover the remaining 75% to 80% of total green investment needs.
The authors say more connected European capital markets could help draw private funding to green projects. They also point to public policy and decisions about where capital is deployed. Those measures matter because the estimated private contribution is larger than the public share.
A separate research paper published by the ECB examines another economic exposure: water scarcity. In a modeled drought with a 100-year return period, the study puts up to 24% of euro area output at risk from shortages of surface water. That is a measure of activity exposed under the scenario, not a forecast that output will fall by 24%.
The researchers estimated that about 9% of output was at risk using country-level inputs, compared with about 24% using finer location data and an enhanced method. The figures come from different analytical approaches, rather than a change in conditions over time. The authors caution that estimates for rare droughts carry substantial uncertainty.
The paper identifies climate change, overexploitation and pollution as pressures behind water-related risks. The ECB says water stress can affect production and supply chains. The drought finding also appeared in EconoTimes’ earlier coverage of the ECB’s ecosystem-services findings.
The ECB is working with other central banks in the European System of Central Banks on a framework to assess how water stress affects the EU economy.
