Lars Ehrlén presented on Växjö's goal to become fossil fuel free by reducing carbon dioxide emissions per capita by 50% by 2010 and 70% by 2025 compared to 1993 levels. Växjö has a population of 78,300 and introduced bioenergy in the 1980s due to high oil prices. Currently 50% of Växjö's energy comes from renewable sources like biomass, and the city has implemented district heating, public transport initiatives, and energy efficiency programs to achieve its fossil fuel free vision.
