A smartphone app has been designed to help shoppers choose more environmentally-friendly protein-rich products, namely meat, vegetarian alternatives, eggs and dairy products. The methods and data used to measure these products’ lifecycle environmental impacts are presented in a recent study. In recent years, various apps have been designed to help consumers shop more sustainably by providing information about products’ environmental credentials. The Questionmark is one such app, developed in the Netherlands by an animal welfare NGO in collaboration with an environmental consultancy. Aimed at the Dutch market, it enables consumers to use their phones to scan the barcodes of over 19 000 protein-rich products commonly found in supermarkets. An overall sustainability score is presented for each product, plus further individual scores for human health, climate change, biodiversity, animal welfare and social impacts.
