Chiang Mai University has implemented comprehensive sustainable commuting initiatives that transform campus mobility and reduce environmental impact. The university operates an extensive public transport system featuring electric vehicles and clean energy solutions that serve as a benchmark for sustainable urbanization.
The Purple Bus fleet represents the cornerstone of sustainable transportation infrastructure on campus. These vehicles utilize electric power and compressed biogas derived from biomass waste management facilities, significantly reducing greenhouse gas emissions while providing free public access to 16,000 daily riders across 11 routes. The service operates from 7:00 AM to 9:00 PM, prioritizing walkability and urban mobility through strategically positioned stations that encourage non-motorized transport connections.

For inter-campus transportation between Mae Hia Campus (Faculty of Agro-Industry, Faculty of Veterinary Medicine, Northern Science Park) and Suan Dok Campus (Maharaj Nakorn Chiang Mai Hospital and health science faculties), the university operates 20-seat minibuses and vans. Multiple vehicles in this fleet have been converted to run on compressed biogas (CBG) produced from biomass waste collected within the university and Suthep subdistrict. This biogas is processed at the Biomass Management Center located at Mae Hia Campus, significantly reducing greenhouse gas emissions from campus transportation operations.

Advanced smart cities technology enhances the system through AI-powered monitoring and real-time tracking via mobile applications, enabling efficient resource management and improved accessibility. LED displays communicate route information and university announcements, while integrated CCTV systems ensure passenger safety. The fleet includes specially adapted vehicles for persons with disabilities, promoting inclusive cities and equal transportation access for all community members.
Beyond conventional transit, the university promotes cycling infrastructure through bike lanes and anywheel bicycle sharing services distributed throughout green spaces. EV charging stations at Mae Hia Campus further encourage electric vehicle adoption among staff and students, supporting the transition to sustainable architecture and energy-efficient transportation.

These initiatives demonstrate commitment to disaster risk reduction through decreased air pollution and reduced urban heat island effects. By integrating public transport with pedestrian-priority planning and green buildings standards, the university creates a resilient urban environment. The comprehensive approach earned recognition with the Smart City Solution Award 2024 in Smart Mobility, validating its contribution to sustainable cities development.

The sustainable commuting program exemplifies university leadership in addressing urbanization challenges while fostering inclusive communities. Through continuous infrastructure investment in urban planning and cultural heritage preservation alongside modern mobility solutions, Chiang Mai University advances toward carbon neutrality and exemplifies responsible urban development practices aligned with SDG 11.
