A new study led by the Potsdam Institute for Climate Impact Research emphasizes the importance of reducing car commutes in urban areas to tackle greenhouse gas emissions. The research highlights the need for homes to be located close to city centers and workplaces, with well-targeted building densification identified as a critical lever in reducing emissions. Using data from major cities, the study found direct links between urban structure and car commuting patterns, suggesting that urban density and transport links play a secondary role. Planners can utilize GPS data, travel patterns, and artificial intelligence to determine effective measures to combat climate change by reducing car commutes.
