Study from 200910 found organic free-range eggs could come with an unexpected climate cost and may not be the greenest choice after all

Buying organic free-range eggs feels like the ultimate green choice. But new research from the University of Oxford shows an unexpected climate cost. Going 100% organic free-range actually surges greenhouse gas emissions by 60% and doubles land use. Free-range hens eat more feed and suffer higher mortality. Better animal welfare is vital, but cage-free eggs carry a massive hidden carbon footprint. The truth is far more complex.
