AREP and its partners won an international and multidisciplinary consultation led by the Grand Duchy of Luxembourg and conducted a vast prospective study between 2020 and 2022 in Luxembourg and its functional region.

The goal was to map out a pathway to ecological transition by 2050 for Luxembourg and its cross-border metropolitan area.

What kind of spatial planning strategies can help achieve carbon neutrality by 2050? Spatial planning constitutes a fundamental matrix, likely to slow down or, on the contrary, to accelerate the shift in our lifestyles. The prospective study carried out by AREP and its partners (TAKTYK, Quattrolibri, Bureau Mobil’Homme BMH and the Institute for Environmental Transition of the Sorbonne University) aimed to map out a pathway to building a resilient and carbon-free future by 2050 for Luxembourg and its functional region. The challenge is enormous, both in terms of soil preservation and reduction of greenhouse gas emissions, as we are dealing with one of the highest carbon footprints in Europe.

In the face of the pressing environmental challenges, we have had the opportunity to develop a digital model, Flux, which has supported our reflection at a regional scale. By encouraging iteration between project and carbon metrics, f(lux) made connections between proposals and “ecological value”, through our project methodology.

To carry out this prospective study, the team proceeded in three stages. The first one consisted in understanding the context of the Luxembourg functional region and in preparing the ground for the methodology to apply. During the second stage we unfolded our strategic vision. The third stage led to a manifesto which summarises our vision in 16 key actions, details three lines of research and provides an overview of demonstration projects on five pilot sites.
