Hållbarhetslabb – ett konkret sätt att skapa hållbara städer Städer står inför många utmaningar. Redan idag koncentrerar städer utsläppsintensiva aktiviteter såsom transporter, boende och konsumtion och lider också av negativa effekter av utsläppen i form av ett förändrat klimat med bland annat värmeböljor eller översvämningar. Sociala problem som till exempel segregation är inte heller ovanligt Cities face growing pressures from increasing populations, giving rise to environmental and social problems. The transition towards more sustainable urban areas has thus become an urgent matter, demanding innovative solutions and means to test and deploy them. Urban Living Labs (ULLs) have emerged as a new approach to experimentation in real-life city settings. This thesis seeks to examine how ULL
