An overarching consensus exists on the substantial environmental benefits of food waste reduction. On the other hand, one study looking at food waste reduction measures in the United Kingdom found that rebound effect may cause substitutive consumption as a result of economic savings made from food waste prevention. They estimated that a reduction of one metric tonne of food waste could lead to substantial reductions in GHG emissions, in the order of 706–896 kg CO2-eq. Rebound effect may however reduce such GHG savings by up to 60%.
