Efficient = Sustainable The U.S. soybean industry has been trying to convince the EU that its soydiesel should be considered sustainable under Europe’s Renewable Energy Directive (RED). Now a study published this week in the journal Nature Sustainability affirms the U.S. industry’s assertions that its high yield approach has lower per unit adverse externalities than practices that “appear” to be eco-friendly. For example, the researchers found that EU organic dairy farming causes one-third more soil loss and requires twice the land as conventional dairy farming. In short, more efficient systems have lower environmental impact. The use of biotech soybeans has boosted yields per acre while reducing inputs, including l...
