Each year, the United States spends almost a trillion dollars attempting to combat metallic corrosion, an electrochemical reaction which occurs when metals oxidize and begin to rust. Now, a team of researchers led by the Ohio State University (OSU) has estimated how much corrosion is gradually worsening global carbon emissions.  Although previous research has already estimated the economic cost of corrosion to be about three to four percent of United States’ gross domestic product, this is the first study to quantify the environmental impact associated with steel...
