Green Finance Guide
The Green Finance Guide provides cities with a comprehensive overview of financial instruments and mechanisms across various sectors and stages of project development to support sustainable urban projects. Its objective is to help municipalities navigate green funding options, ensuring they can access, combine and apply innovative financing solutions for effective climate action.
It is designed to:
- Inform municipalities about a wide range of available financial instruments
- Offer high-level guidance on how to blend or sequence these instruments
- Highlight key stakeholders involved in the provision of climate finance
- Showcase real-world examples of how instruments have been successfully applied
- Provide access to relevant financing and technical assistance programmes across Europe

The tool is organised into a series of modules:
- Core modules (Financial Instruments, Case Studies, Financing & Technical Assistance Programmes) are structured as searchable databases that allow users to filter, identify and explore options relevant to their context.
- Complementary modules provide high-level guidance and explanatory support, helping users understand how to navigate the broader climate finance landscape, structure appropriate financing approaches for their local context and engage with relevant stakeholders throughout the funding process.
Together, these modules aim to either support early-stage project planning or upscaling by helping cities identify appropriate financing strategies, key stakeholders and programmes and draw insights from real-world examples.
Expected outcomes:
- Cities become more familiar with green finance options and their applications
- Improved access to a wide range of green financial instruments
- Greater capacity for cities to fund and implement sustainable projects across multiple sectors
- Municipalities develop investor-ready green project pipelines
- Enhanced ability to tailor financial strategies to specific project needs

- UP-SCALING – Securing funding for expanding successful interventions
