This paper estimates the impact of policy measures aimed at increasing fruit and vegetable (F&V) consumption in the UK over more than a decade, evaluating changes in purchased quantities and estimating the corresponding greenhouse gas emissions (GHGEs). We use a counterfactual scenario analysis to isolate the effects of the policy from the influences of evolving prices, incomes and socio-demographic factors. Our estimates suggest that the positive effects of the promotion campaigns on F&V purchases (about half a portion per adult equivalent per day) still persist 10 years after the start of the policy implementation, and we find no evidence of a wearout effect. We also provide suggestive evidence that the dietary adjustment which accompanies the increase in F&V intakes translates into a relevant reduction in GHGEs, by an average amount of 3.3kg of CO2e per adult equivalent per month.

Abstract
This paper estimates the impact of policy measures aimed at increasing fruit and vegetable (F&V) consumption in the UK over more than a decade, evaluating changes in purchased quantities and estimating the corresponding greenhouse gas emissions (GHGEs). We use a counterfactual scenario analysis to isolate the effects of the policy from the influences of evolving prices, incomes and socio-demographic factors. Our estimates suggest that the positive effects of the promotion campaigns on F&V purchases (about half a portion per adult equivalent per day) still persist 10 years after the start of the policy implementation, and we find no evidence of a wearout effect. We also provide suggestive evidence that the dietary adjustment which accompanies the increase in F&V intakes translates into a relevant reduction in GHGEs, by an average amount of 3.3kg of CO2e per adult equivalent per month.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
