The Mexican government is working hard to reduce the carbon footprint of the state-run oil company PEMEX, but the results thus far have been uneven at best. PEMEX has placed a high priority on actions that will help protect the environment, such as steps to greatly reduce emissions at some processing plants and introducing ethanol into the mix for gasoline in the three largest cities. But critics say these steps are very small when compared with the overall damage that the company has continued causing to the air, soil, and water in Mexico in recent years. Even some solutions, such as using more ethanol, have raised concerns that demand for raw materials will raise food prices in Mexico.
