New research from The University of Texas at Austin finds industrial buildout in oil, gas and petrochemical sectors in the U.S. Gulf Coast and Southwest regions could generate more than half a billion tons of additional greenhouse gas emissions per year by 2030. That figure is equivalent to 8 percent of total current annual U.S. emissions. These emissions are driven by the regions’ oil and gas boom, and a substantial fraction comes from large industrial facilities such as new petrochemical plants, liquefied natural gas export terminals and refineries. The vast majority of these emissions will come from Texas and Louisiana.
