#unleaded

Prior to 1970, buying leaded gasoline in the United States was as normal as picking up a carton of eggs or relaxing in your asbestos-laden home. After 1970, the U.S. Congress had officially adopted the Clean Air Act created the Environmental Protection Agency (EPA), and the gradual phasing out of leaded fuel began. While many bemoaned the lackluster performance of the malaise-era automobiles that followed, the rules continued to inform how vehicle manufacturers operated on a global scale.

But leaded gasoline hung in there for longer than you might assume. Most Western nations (including the United States) didn’t totally phase out leaded gasoline intended for passenger vehicles until the 1990s. Central Asia took even longer and parts of the Middle East and Africa continued to offer lead additives well into the 2000s. However, the United Nations Environment Program announced that leaded gasoline had officially become extinct over the summer, with Algeria being the final country to deplete its now-banned supply.
