What is the Neighbourhood Heat Stress Action Plan (NHSAP)?


As cities across North-West Europe become increasingly vulnerable to extreme heat, Cool Neighbourhoods is taking a proactive step: helping local authorities create Neighbourhood Heat Stress Action Plans (NHSAPs).

These NHSAPs are strategic, locally driven plans that help municipalities, community groups, and urban planners identify heat-related risks and take practical, evidence-based actions to protect the most vulnerable — while making neighbourhoods greener, cooler, and more liveable.



What does an NHSAP include?

Each NHSAP follows a structured but flexible format, meaning it can be adapted to different urban contexts. A typical plan includes:

✅ Heat Vulnerability Mapping
Combining sensor data, citizen science, and satellite imagery to pinpoint the hottest areas and who is most affected.

✅ Local Risk Analysis
Identifying physical (e.g. lack of green space, concrete dominance) and social (e.g. elderly populations, isolated households) vulnerabilities.

✅ Targeted Interventions
Greening, shading, water retention, reflective surfaces, and community cooling strategies tailored to the neighbourhood’s specific needs.

✅ Community Engagement
Involving residents in both the design and implementation of actions — from planting trees to monitoring progress.

✅ Monitoring & Evaluation
Using clear indicators to track impact and guide future improvements.

Who benefits from NHSAPs?

NHSAPs are designed to directly benefit:

  • Local Authorities — by offering an adaptable, ready-to-use framework to tackle heat risk.
  • Urban Planners & Environmental Officers — with data-driven guidance for interventions.
  • Vulnerable Residents — who are often most at risk during heatwaves.
  • NGOs, Schools, and Community Organisations — who can engage with the action plans as a means of education, resilience-building, and empowerment.
  • Regional and EU Policymakers — as evidence for funding climate adaptation at the neighbourhood scale.

How are they developed?

NHSAPs are co-created using the Joint Training Scheme developed within Cool Neighbourhoods. This hands-on process combines expert input, citizen participation, and pilot testing to ensure each plan is:

  • Locally owned and community-based
  • Scalable across different regions
  • Replicable beyond the nine Cool Neighbourhoods pilot areas
  • Measurable and impactful over time

 

What’s next?

All nine Cool Neighbourhoods pilot sites — in France, Belgium, the Netherlands, and Luxembourg — are developing their own NHSAPs. These will be showcased in late 2025, alongside open-access templates and toolkits for broader replication across Europe.

As temperatures continue to rise, NHSAPs are a vital tool to protect urban populations, especially the most vulnerable, and to build climate resilience from the ground up.
