A mission: understanding how public-private partnerships (PPPs) are reshaping urban planning to create sustainable and inclusive districts in Luxembourg, such as Belval and Metzeschmelz.
An approach: seeking insights from three key figures in these urban developments: Marie-Josée Vidal, Premier Government Counselor and President of AGORA, Simone Asselborn-Bintz, Mayor of Sanem, and Christian Weis, Mayor of Esch-sur-Alzette.
Once dominated by ArcelorMittal’s steel furnaces, Belval and Metzeschmelz are now vibrant districts, thanks to a groundbreaking collaboration between the steel giant and the Luxembourgish government (via AGORA). These projects illustrate how a PPP can drive urban development and build a sustainable future for the region.
But what makes a PPP successful? How do the elements align to create a winning formula? It’s a delicate balance: how can government ministries, focused on public service, collaborate effectively with large corporations seeking profitability? This investigation delves into the workings of Belval and Metzeschmelz, where innovation and cooperation are the guiding principles.
A Model Combining Efficiency and Responsibility
For Marie-Josée Vidal, PPPs are fundamentally about “combining strengths to accelerate tangible results.” This model allows for risk-sharing while optimizing timeframes and costs. “Public-private partnerships combine the speed and efficiency of the private sector with the responsibility and public interest focus of the public sector. This synergy enhances efficiency at every stage of urban development.”
She further explains:
“The private sector brings flexibility and innovation, while the public sector ensures the protection of collective interests. This is clearly demonstrated at Metzeschmelz, where we are pioneering new solutions in mobility, energy, and water management. In Belval, this model has transformed an industrial wasteland into a dynamic district within just a few decades, all while meeting sustainability and quality-of-life objectives.”

Beyond efficiency, PPPs naturally align with various government programs. For instance, Marie-Josée Vidal highlights how AGORA and ArcelorMittal’s values resonate perfectly with the objectives of the Pacte Logement 2.0, a cornerstone of Luxembourg’s housing policies. This initiative fosters closer collaboration between public and private entities to accelerate the development of affordable and sustainable housing.
Another major advantage, as pointed out by Simone Asselborn-Bintz, Mayor of Sanem: “PPPs enable the mobilization of private funding, easing the burden on public resources and expediting the completion of complex projects.”
A Network of Shared Interests
Are the objectives of the government and private sector truly at odds? Luxembourg’s experience suggests otherwise. Public-private dialogue thrives when based on solid common ground.
Simone Asselborn-Bintz identifies two essential pillars: “Careful selection of partners and the establishment of a lasting relationship of trust based on shared objectives.” It’s not just about collaboration—it’s about fostering synergy where private sector economic goals and public interests, such as sustainability and social inclusion, converge.
“This requires complete transparency and continuous communication to ensure that every decision respects community needs and the project’s core values.” – Simone Asselborn-Bintz, Mayor of Sanem
The experiences of these three experts lead to the same conclusion: by adhering to these principles, it becomes evident that public and private interests are not mutually exclusive.
“It’s a mistake to view the private sector solely through a profit-driven lens,” notes Marie-Josée Vidal. “Luxembourgish companies seek profitability, but they are also key players in social cohesion and the common good. Similarly, the government aims to foster economic and financial development while serving the public interest. With open dialogue and exchange, we can develop solutions that satisfy all stakeholders.”
Overcoming Challenges
However, PPPs are not without obstacles. Bureaucracy, as well as cultural and organizational differences between public and private entities, necessitate close and continuous collaboration. For Christian Weis, Mayor of Esch-sur-Alzette, these challenges should not be seen as roadblocks but rather as opportunities for greater diligence.
“Administrative constraints, while sometimes burdensome, ensure project quality and integrity. They provide a necessary framework to guarantee that projects meet both quality standards and societal expectations. Processes such as public tenders and strict regulations are crucial tools for enhancing the reliability and longevity of urban initiatives.”

Simone Asselborn-Bintz highlights other risks, such as power imbalances and concerns about long-term PPP commitments placing a burden on future generations. “These challenges require heightened vigilance,” she acknowledges.
“A solid regulatory framework and clear objectives are essential.” To illustrate this, she references the National Plan for Sustainable Development, which integrates sustainability into public projects through recognized environmental certifications like DGNB and BREEAM. “By adopting such a common framework, we establish strict standards for quality, environmental impact, and social responsibility, ensuring a clear foundation for resolving potential disputes.”
This structured approach fosters true synergy between public objectives and economic imperatives. “This is how we encourage the most innovative solutions for building sustainable districts,” says Christian Weis. In Metzeschmelz, for example, cutting-edge technologies are being tested for energy management, mobility, and ecological restoration—blending sustainability with economic performance. All of this operates within a clearly defined framework, established with input from all stakeholders.
A Model with Global Influence
Luxembourg, a nation known for its balanced approach to public-private collaboration, has successfully implemented PPPs. Beyond the country’s borders, the AGORA model is gaining international recognition. As Marie-Josée Vidal points out:
“Countries like France are studying our approach to repurposing industrial wastelands. AGORA’s 50-50 structure is unique in Europe. Belval, an urban laboratory, has become a symbol of innovation. The AGORA model could redefine international standards for PPPs.”
– Marie-Josée Vidal
Christian Weis, always attentive to Luxembourg’s role in Europe, fully agrees: “With projects like Belval, our country has become a benchmark for urban development innovation. We have successfully transformed industrial sites into modern, sustainable districts while preserving our historical heritage. Many of the developments in Belval now attract visitors from around the world.”
As PPPs continue to reshape Luxembourg’s urban landscape, they also prompt key questions for the future: How can their impact on ecological transition be further amplified? What new forms of cooperation might emerge? Perhaps Belval and Metzeschmelz are only the beginning of a broader movement where innovation, sustainability, and inclusion intertwine to redefine the cities of tomorrow.
