The bill establishes the Climate Change Impact Assessment Council in Texas, tasked with studying the effects of climate change on the state's residents, natural resources, public health, and economy. The council will consist of two members from the Senate, two from the House of Representatives, and seven public members with expertise in various relevant fields, including climatology, the economy, land management, and tourism. Public members will be reimbursed for travel expenses incurred while conducting council business, and legislative committees will provide necessary support. The council is required to conduct a comprehensive study, hold public hearings, and submit a report to the legislature by January 1, 2027.

The council's study will assess the current and potential impacts of climate change, estimate associated costs, research preventive measures for climate-related issues such as flooding and drought, and recommend legislation to mitigate adverse effects. The council is set to be abolished, and the act will expire on September 1, 2027. Appointments to the council must be completed by March 1, 2026, and the act will take effect 91 days after the legislative session concludes.
