Thailand's major developer Sansiri is positioning sustainability as core business strategy, targeting Net Zero 2050 through three initiatives: green architecture/design, innovative green precast construction (15% waste reduction), and carbon-conscious procurement. Already deployed 1,200 EV charging stations, 3,800 solar installations, and reduced emissions by 7,000 tCO2e. The SANSIRI T77 campus in Onnuch is being positioned as a "clean energy city" model with mixed-use development across 70 rai. This reflects Thailand's broader shift toward ESG-aligned real estate and demonstrates integration of sustainability with profitable operations.
