An innovative, neutral platform delivering financial expertise to bridge the urban climate investment gap across Europe.
The Climate City Capital Hub (Capital Hub) is an innovative, neutral platform that catalyses climate-related financing activity. Led by BwB as part of the NetZeroCities programme, the Capital Hub works directly with cities and regions in the EU and neighbouring European countries to turn climate mitigation and adaptation ambitions into bankable, investable propositions – connecting urban climate plans with the private and public capital needed to deliver them.
The Capital Hub supports Climate-Neutral and Smart Cities Mission cities and Adaptation to Climate Change Mission signatories, providing the tailored financial expertise and investment structuring support needed to make their climate projects investable.
Urban areas are at the frontline of climate mitigation and adaptation – responsible for a significant share of Europe's emissions while simultaneously facing increasing exposure to climate-related risks. Yet most municipalities lack the financial knowledge, structured project pipelines, and investment market relationships needed to translate their climate ambitions into funded, implementation-ready projects.
Three structural issues define the challenge the Capital Hub was created to solve:
BwB research indicates that €307 billion in incremental expenditure is needed for 100 EU Cities Mission cities to deliver on their climate commitments through to 2030 – with 80% of that capital required from private sources. This shortfall is not unique to Mission Cities; it reflects a wider challenge across Europe where existing public resources are insufficient to meet the scale and urgency of investment required to meet mitigation and adaptation needs.
Large pools of private capital are looking to deploy into urban climate infrastructure, but a shortage of well-structured, investment-ready projects is preventing that investment from reaching cities and regions.
City and regional authorities rarely have the in-house financial expertise or staff resources needed to transform climate action plans into bankable projects at scale and across multiple sectors simultaneously.
The Capital Hub operates through a set of complementary functions, spanning the full journey from project development to capital commitment.
Engaging directly with cities and regions, centred on bankability principles and investor expectations – building the local knowledge and institutional confidence needed to develop investable projects.
Providing end-to-end project preparation of mitigation and adaptation projects, spanning direct technical assistance (TA) and facilitation of access to wider TA programmes, through to full financial structuring – covering financial modelling, delivery mechanisms, risk allocation, and investment structuring.
Supporting with sector-specific approaches – across built environment, energy, mobility, and waste and circularity – as well as broader city-wide and regional portfolios that bring together projects from multiple sectors into single, bankable investment opportunities.
Designing innovative financing pathways and investment models that can be replicated across cities and regions – turning individual project solutions into scalable approaches that drive systemic change.
Aligning national and EU programmes, public financiers, and private investors through structured engagement – building the coalitions and market infrastructure through which sustained capital can flow.
Supporting deal structuring and helping to connect projects with appropriate capital providers – facilitating the conditions under which financing commitments can be made.
On-the-ground expertise, supporting project development and facilitating capital flows.
Direct project preparation support as well as assistance with access to wider TA programmes – bridging the gap between climate action planning and financially structured, investment-ready projects.
An independent unit – neutral to any capital provider or institution – facilitating market access for projects.
A strong emphasis on building the evidence base that underpins successful city outcomes and compelling investor propositions.
Providing the financial expertise and structured support needed to develop bankable projects and engage successfully with capital markets.
Offering access to a growing, well-structured pipeline of urban climate projects across a range of size, return, sector, and geographic profiles.
Coordinating with national and EU programmes to align public and private capital around shared climate investment priorities.
Collaborating with the wider NetZeroCities ecosystem and European technical assistance programmes to maximise the impact of project preparation support.
