Malta Challenge: Urban Heat Mitigation
Malta, April 16, 2026 / TRAVELINDEX / Malta is one of the smallest and most densely populated states in the European Union. As of 2024, its estimated population is 563,443, resulting in a density of approximately 1.7 inhabitants per-km².
Malta’s tourism revenue growth is one of the highest among southern Mediterranean destinations. In 2024, it received 3.56 million visitors, up 20% over the previous year.
One of the current issues Malta faces is the lack of natural shade in its urban and tourist areas. As temperatures continue to rise across the Mediterranean region and globally, this shortage not only exacerbates the effects of high temperatures and heatwaves but also directly impacts the quality of life for residents and the experience of visitors.
This situation is due to several factors:
- Climate and soil: Malta has a Mediterranean climate with hot, dry summers. Combined with its limestone-based soil and limited availability of freshwater, this makes it difficult for trees and dense vegetation to thrive.
- History of deforestation: Human activity has led to widespread deforestation for various purposes, resulting in the near-total absence of natural forests today.
- High population density and urbanization: Intense urban development and high population density have limited the available space for green areas and tree planting.
This lack of shade contributes to the urban heat island effect, affecting residents’ quality of life and the experience of tourists, especially during the hottest months, and increasing the need for climate-resilient urban solutions.
To address this issue, innovative green technology (green tech) solutions are being considered, such as the implementation of green infrastructure, living roofs, and green corridors that can provide shade and improve thermal comfort and support local efforts to adapt urban spaces to increasing heat in urban areas.
The limitations of soil fertility hinder the planting of traditional trees and vegetation, demanding new solutions adapted to the local context.
Innovation Opportunity
In this environment, green innovation emerges as a key tool to help cities adapt to rising temperatures while enhancing the liveability of public spaces. This challenge aims to identify sustainable technological solutions that provide shade through green infrastructure, innovative materials, smart urban design, or bioinspired technologies. The goal is to enhance the liability of public spaces, promote high-quality tourism, and strengthen community well-being.
Challenge Objectives
- Mitigate urban heat and strengthen climate resilience: Promote innovative solutions that improve thermal comfort through green structures, living roofs, green corridors, or smart shading technologies.
- Improve the Tourist Experience: Increase the time spent and enjoyment of tourists in open spaces by creating more comfortable, cooler, and visually appealing environments.
- Enhance Residents’ Quality of Life: Reduce the impact of extreme heat in urban and recreational areas, improving public health and community interaction.
- Promote the Green Economy: Stimulate entrepreneurship in green technologies, sustainable architecture, urban agriculture, and climate-adapted infrastructure solutions.
Collaboration Activities
- Challenge Launch: National and international announcement of an open call for innovative companies, scaleups and startups (with an existing product or a pilot project) with proposals for Malta.
- Bootcamp (Optional: online or physical) Selected participants will take part in an intensive training process (bootcamp) with experts in sustainable architecture, urban design, climate technology, and regenerative tourism.
- Final Presentation Event: Presentation of solutions before a panel composed of Maltese government representatives, tourism agencies, investors, and strategic partners.
- Awards and Implementation: Winning projects will receive national visibility, and institutional support to scale up their solutions.
- Pilot Project: Implementation of pilot initiatives in key areas (squares, bus stops, tourist zones) with technical and community monitoring.
