About LUCI

The Leadership for Urban Climate Investment (LUCI) initiative raises ambition through four quantifiable, trackable targets, helping select Alliance members implement bold and effective targets. LUCI enables these ambitious targets by catalyzing action along the entire pipeline of subnational climate finance from project conception through financing. Hosted by the Alliance, LUCI was initiated by a multi-stakeholder coalition led by the German Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) at the UN SG Climate Summit in 2019.

Case Studies: LUCI Initiatives are Driving Impact on the Ground

The City Climate Finance Gap Fund: Early-Stage Project Support Podgorica, Montenegro


The new Gap Fund, one central initiative of LUCI, is the first global fund dedicated to supporting cities in the very early stages of project development, with an aim to unlock EUR 4 billion of investment off a target EUR 100 million budget. In Podgorica, The Gap Fund is supporting the city in mapping relevant public buildings to help identify which ones could be suitable for green roofs combined with facades to improve energy efficiency in buildings and increase the permeability of surfaces in public spaces. Cities can apply directly for early-stage project support or learn more through networks like GCoM, C40, and ICLEI.

R20 – Leading on Innovative Approaches to Subnational climate finance


R20 – Regions of Climate Action, Pegasus Capital Advisors, the International Union for Conservation of Nature, BNP Paribas, and Gold Standard have partnered to launch the Sub-national Climate Finance Initiative (SCF). The newly launched SCF, incubated and supported by The Global Innovation Lab for Climate Finance, will target mitigation and adaptation projects at the sub-national level, specifically at the deal size of USD 5 million to 75 million. With Green Climate Fund anchor funding and first-loss coverage, this is the first time an impact equity fund mobilizes public (20%) and private sector (80%) funding at scale to de-risk sub-national middle scale infrastructure projects.
