Proximity-based cities emit less mobility-driven CO$_2$ In the quest for more environmentally sustainable urban areas, the concept of the 15-minute city has been proposed to encourage active mobility, primarily through walking and cycling. An urban area is considered a ``15-minute city" if every resident can access essential services within a 15-minute walk or bike ride from their home. However, there is an ongoing debate about the effectiveness of this model in reducing car usage and carbon emissions. In this study, we conduct a large-scale data-driven analysis to evaluate the impact of service proximity to homes on CO$_2$ emissions. By examining nearly 400 cities worldwide, we discover that, within the same city, areas with services located closer to residents produce less CO$_2$ emissions per capita from transportation. We establish a clear relationship between the proximity of services and CO$_2$ emissions for each city. Additionally, we quantify the potential reduction in emissions for 30 cities if they optimise the location of their services. This optimisation maintains each city's total number of services while redistributing them to ensure equal accessibility throughout the entire urban area. Our findings indicate that improving the proximity of services can significantly reduce expected urban emissions related to transportation.

An incredible week! 🌟 Proud to have been part of the organizing team, awed by Norrköping’s beautiful views and amazing food, and inspired by conversations with colleagues from around the globe.
Thank you for making this experience so unique, see you at the next one! #ic2s2

So grateful and proud to be part of this year's #ic2s2. All these kind words about today’s tutorials mean the world. Thank you!

Look forward to it!

🔍 Key insights:
• Foreign-born minorities often remain socially segregated even while mobile
• Limited mobility range and reduced access to public transport are major barriers
• Improving transport accessibility could meaningfully reduce experienced segregation

Using large-scale smartphone data from Sweden, we show how mobility—or the lack of it—shapes the experienced socio-spatial segregation of foreign-born populations beyond residential neighborhoods.

💡It was a pleasure to share my research.
My talk focused on how we can use large-scale human mobility data to support sustainable and inclusive mobility.
Thank you to the Institute for Analytical Sociology and all participants for an inspiring exchange of ideas!

👇Germany's €49 Deutschlandticket boosted public transport use, seeing a greater increase among lower socioeconomic groups, according to our study using mobile geolocation data (11M+ devices). #publictransport #farecuts #mobility

Day 30 of #30DayMapChallenge: The final map. Visitors travel distances during the first month of the D-Ticket (May 2023). I’m proud to have completed all 30 days of the map challenge. The experience was both immensely fun and deeply rewarding.

Day 29 of #30DayMapChallenge: Overture. Buildings and places in Linköping, Sweden.

Day 28 of #30DayMapChallenge: The blue planet. The largest lake in Sweden by area.

Thanks! We have Section 6.4 Transport accessibility which covers some of these aspects. We also reviewed a few housing, public transport, and urban design practices that affect segregation in Table B.2.
