The shipping industry is coming to grips with its egregious carbon footprint, as it has an outsized contribution to greenhouse gas emissions and to the dumping of chemicals into open seas. Already, the global shipping industry contributes about 2 percent of global carbon emissions, about the same as Germany, as the BBC reported.

In its efforts to clean up its act, the industry is looking to stop burning diesel and is exploring using ammonia as its fuel source. When ammonia burns, it does not create carbon dioxide emissions, as the BBC reported.
