RESEARCH PAPER PRESENTATION
5-UP framework for closing city climate implementation gaps
Study of 10 European cities proposes the 5-UP framework to turn climate plans into coordinated implementation across mitigation, adaptation, and justice.
A systemic five-dimension framework can help cities close persistent gaps between climate plans and meaningful implementation.
The authors investigate whether climate action in cities can be implemented more consistently when planning, capacity building, piloting, scaling, and knowledge uptake are treated as linked stages rather than isolated tasks. Using evidence from 10 European cities, the paper tests whether a flexible systems approach can better integrate mitigation, adaptation, and social justice. It also explores whether implementation barriers arise before, during, and after action, requiring support beyond finance and project outputs.
The problem
Cities are adopting ambitious climate goals, but many struggle to convert plans into sustained action. Implementation is often fragmented, project-led, siloed, and under-resourced, while technical capacity, governance coordination, and long-term funding remain weak. These gaps matter because cities are central to climate mitigation and adaptation, yet delayed or inconsistent delivery can worsen risk, inefficiency, and inequality.
Key findings
- Financial constraints were the most frequently reported implementation barrier, with structural lack of resources accounting for 42% of quotations and high upfront costs making up 26% of economic constraints.
- The 5-UP Framework most improved cities' clarity on needs, policies, and instruments, with UPDATE scoring 3.6 out of 5 and municipal climate knowledge scoring 3.9.
- Major implementation bottlenecks remained in technical translation and finance, with translating concepts into technical detail scoring 2.3, tool implementation 2.6, and financing for upscaling only 1.8.

What cities should do
Overall, the paper suggests that cities seeking more reliable climate delivery—especially municipalities with siloed governance or limited implementation capacity—should use a staged, systemic approach rather than isolated projects.
- Map local needs, policy gaps, and stakeholders before selecting interventions.
- Build climate literacy across departments, not only in climate offices.
- Pair plans with technical studies, detailed designs, and implementation-ready tools.
- Use pilots to adapt solutions to local conditions before wider rollout.
- Embed successful actions in formal planning and governance frameworks.
- Design financing pathways that cover preparation, piloting, and scale-up.
- Communicate climate action in accessible language to broaden ownership.
- Integrate mitigation, adaptation, and social justice in the same process.
Implementation Approach
The implementation approach is structured as a sequential but interconnected process across five dimensions. Cities begin by diagnosing needs and governance conditions, then strengthen capabilities, test solutions in context, create pathways for institutionalization and scaling, and continuously communicate and disseminate lessons. The approach is flexible, allowing cities to tailor actions to local conditions while maintaining a systemic logic.
Phase 1: Diagnose
Assess local needs, barriers, policies, data conditions, and stakeholder landscapes to define a shared climate vision.
Phase 2: Build capacity
Train municipal actors, match cities with tools or providers, and strengthen technical and organizational readiness.
Phase 3: Pilot
Co-create and test interventions, tools, guidelines, or planning pathways in neighborhoods to make action concrete.
Phase 4: Institutionalize and scale
Embed successful approaches in planning frameworks, governance arrangements, and financing mechanisms for wider rollout.
Phase 5: Uptake and dissemination
Share results, clarify concepts, engage external stakeholders, and spread usable knowledge across sectors and networks.
