Since 1990, the U.S. Gross Domestic Product is up nearly 200 percent, our population has grown by 30 percent, vehicle miles traveled are up 40 percent and energy consumption is up more than 15 percent. We cut the six most common emissions by nearly 70 percent and ozone levels have decreased by more than 30 percent. As of 2017, we have reduced sulfur levels in gasoline by 97 percent. We have preserved and protected land and water resources by implementing waste management programs and adhering to federal guidelines that govern effluent discharge, hazardous waste disposal and other priority areas.
We have made great progress in environmental stewardship under the Clean Air Act, the Clean Water Act and many other environmental regulations, and continue to innovate to evolve our operations and products. While we support sound policies and regulations, and the goal of reducing emissions, we oppose regulations that make unreasonable and often conflicting demands on U.S. refiners and petrochemical manufacturers to make major changes in their processes.
