UNSDGs Influencing the design of Copenhagen’s Future Metro Lines
For the sustainable development of a city, mobility and mass transit systems are generally recognized as having a positive impact. This has been the case for the introduction of the M1/M2 metro lines in Copenhagen between 1997 and 2002, and more recently the opening of M3 and M4 in 2019 and 2020, respectively. However, we also need to acknowledge that the development of infrastructure, such as new underground metro lines, requires a huge resource use, especially concrete, and have a large embodied CO2. This paper sets out how the UNSDGs have been used to influence the design decisions made during the early phases of the project and how targets shall be defined for future phases, with the aim for more sustainable future projects. Furthermore, it explores how the adoption of ’different thinking’ and innovation may help to deliver those targets and the challenges involved.
