E-Mail Subsidising low carbon emission meals could encourage more people to choose them, according to new research. The study, led by Queen Mary University of London, investigated the impact of different interventions on encouraging people to select low carbon emission menu options in a simulated lunchtime canteen environment. This included the use of carbon taxes and subsidies, traffic light labelling (TLL) and social norms, where more sustainable options were highlighted as the most popular menu items. Carbon taxes and either behavioral intervention - TLL or social norms - had a limited effect on shifting behaviours towards meal choices with lower carbon footprints. However, when all these interventions were combined with subsidies, where the money collected from carbon taxes for meat meals was added to vegetable only options, the researchers observed a 24 per cent reduction in weekly carbon emissions.
