Abstract

To decarbonize our urban futures and mitigate climate change, the reduction of CO2 emissions of private households is key within a holistic transition of our society towards more sustainable models of production and consumption. The areas of housing, mobility, food, leisure activities and consumption of goods and services are equally important for a holistic approach towards a low-carbon society. The Carbon Coaching App SUSLA (www.susla.app) is result of the international Sustainable Lifestyles Accelerator (SLA) project and allows the assessment of household carbon and material footprints, the roadmapping of individualized reduction pathways and the tracking of results over time. With partners in seven countries (Germany, Finland, Switzerland, Denmark, Spain, Mexico, India) results with a small number of pilot families showed a footprint reduction potential of around 15-20% through behavioral change after a 3- month experimentation period. 7 pilot households in Spain were able to design their personal transition pathways 2030 with a reduction of their Carbon Footprint of 36 % on average. During the experimental phase of 3 months households achieved an average Carbon Footprint reduction of 13%. Since 2021 SUSLA is regularly used at UPC for footprint calculation of students, roadmapping, tracking and sharing of experiences within the LOW3 Living Lab. Collective Carbon Footprinting shows to be an important driving force for transformative sustainability education, empowering individuals to change their lifestyles and collectively approach the challenges of societal change.
