From the start of LACONIA in September 2020 through August 2025, the project investigated how the rise in solo living affects environmental sustainability, using Denmark as a case study and linking findings to broader European contexts. The research combined in-depth quantitative analysis of national data with qualitative in-home interviews, systematically examining carbon footprints across household types, and identifying social drivers, obstacles, and emerging low-impact alternatives to living alone.
Key results show that one- and two-person households account for 77% of residential carbon emissions in Denmark, with higher per capita impacts among single occupants and wealthier individuals. The project integrated statistical data with narrative vignettes to humanize quantitative findings, illuminating the roles of gender, income, age, and urban context in household energy usage.
Research outputs include five scholarly publications. Main findings have been disseminated broadly, through half-day workshops involving policy makers in Sweden and Denmark, public seminar events, direct engagement with national climate councils, and accessible articles in The Conversation and Buildings & Cities. The project's insights are actively exploited to inform policy development around sustainable housing, urban planning, and inclusivity. The results are also integrated into academic curricula and continue to underpin new research initiatives funded by national and European agencies.
