San Antonio
Texas
Home to the River Walk, the Alamo, and four other Spanish Colonial missions collectively designated as a UNESCO World Heritage Site, the city treats cultural heritage as a foundational driver of its sustainability and resilience strategy. Its 2019 Climate Action and Adaptation Plan identified the circular economy as one of six community mitigation priorities, and in September 2022, San Antonio became the largest city in North America to adopt a deconstruction ordinance, requiring that older housing stock be dismantled and salvaged rather than demolished. Building material reuse has since emerged as a key strategy for advancing an interwoven set of goals — workforce development, resource access, affordable housing, cultural preservation, waste reduction, and urban resilience — with food, textiles, aerospace, and manufacturing identified as additional key sectors for circular economy efforts.
