Heads up to those using cloth “The largest independent study to date, released in 2008 by Britain's Environment Agency, found that the overall impact of cloth versus disposable diapers is highly dependent on how you wash and dry your cloth diapers. For example, if you wash cloth diapers in a full load with water at or below 140 degrees Fahrenheit, line dry the diapers, and reuse them for a second child you would be reducing your global warming impact by 40%. However, if you use a dryer for the diapers and use water above 140 degrees, your impact could be 75% worse than using just disposable diapers. “
