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.
