In 2015, a 25-year-old flooring installer named Roendy Granillo collapsed and died of heat stroke on a construction job in Melissa, a small town northeast of Dallas, after his family said he was denied a water break. They carried his story to Dallas City Hall, and the council passed an ordinance on a 10-5 vote, guaranteeing construction workers a 10-minute rest break every four hours. Austin had passed a similar rule in 2010. The rules stood for more than a decade. Then, in 2023, a single state law erased them both and barred any other Texas city from passing one.
Over the past decade, in a state whose leadership has broadly resisted any sort of climate mandates, a string of Texas cities moved the other way. The four largest, Houston, San Antonio, Dallas, and Austin, each wrote a climate plan and committed to cutting emissions to zero by mid-century. Austin moved its target up to 2040, San Antonio adopted its plan in 2019, Houston pledged a 40 percent cut by 2030, and Dallas wrote money for its plan into the city budget. Smaller places joined in, from San Marcos and Smithville to El Paso, which approved its own plan in early 2026.
