The UN's 2030 Agenda spotlights "sustainable cities and communities" as a pivotal strategy to tackle pressing urban challenges worldwide. In alignment with this vision, Nordic nations - notably Denmark, Finland, and Norway - have championed a plethora of sustainability endeavors. This exhibition unveils such exemplary initiatives from these northern European countries.Highlighted projects include Copenhagen's Kokkedal Village, an innovative approach that harnesses landscape planning to counteract flooding through comprehensive stormwater management. In the same city, the Park and Play initiative transforms parking garage rooftops into outdoor gymnasiums, providing residents with panoramic views of the urban expanse. Helsinki introduces a public sauna, meticulously erected along the shoreline of a quaint island, reminiscent of traditional lakeside saunas. Trondheim, Norway, showcases Ila, an initiative that breathes life back into Iladalen, a previously desolate industrial sector, by revitalizing an ancient watercourse. Lastly, in Helsinki's Jatkasari district, an avant-garde apartment complex stands as a testament to urban greening, with its rooftops adorned with lush gardens and its facades draped in verdant plant life.
