Professor Michela Faccioli examines the effectiveness and welfare impacts of consumer-facing climate policies in the food sector, focusing on carbon taxes and carbon labelling. Drawing on evidence from a survey-based randomized experiment with 5,600 UK participants simulating an online supermarket, the study quantifies how these policies influence purchasing behaviour, carbon abatement, and consumer welfare using an advanced EASI demand model. Results indicate that while carbon taxes alone reduce emissions more effectively than labelling, they also entail higher welfare costs. However, combining taxation with labelling achieves similar emission reductions at substantially lower welfare loss, highlighting their complementary potential as a policy mix. If time permits, Professor Faccioli will also share preliminary insights from a cross-country project in the UK, Italy, and Poland on consumer responsiveness to broader food demand-side mechanisms.
