“…Although some existing research describes the environmental impacts of supermarket products 7 , most literature provides GHGe data on broad categories of products and agricultural commodities and no such datasets have been combined with purchase information 8 . Given that supermarket and packaged food and beverage products dominate consumer dietary intake, evidence is needed to inform policy changes (for example, mandatory GHGe labelling of products) that might meaningfully reduce GHGe 9 , 10 .…”

Switching between similar food and beverage products may reduce greenhouse gas emissions (GHGe). Here, using consumer data linked to 23,550 product-specific GHGe values, we estimated annual GHGe attributable to product purchases consumed at home in Australia and calculated reductions from specific switches. Potential changes to mean Health Star Rating, mean energy density and the proportion of ultraprocessed foods purchased were assessed. Approximately 31 million tonnes of GHGe were attributable to products consumed at home in 2019, the three highest contributors of GHGe being ‘meat and meat products’ (49%), ‘dairy’ (17%) and ‘non-alcoholic beverages’ (16%). Switching higher-emission products for ‘very similar’ lower-emission products could reduce total emissions by 26%. Switches to ‘less similar’ lower-emission products could lead to a 71% reduction. Switches had little impact on the average Health Star Rating, energy density of purchases and proportion of ultraprocessed foods purchased. Directing manufacturing and marketing towards lower-environmental-impact products and signposting such options to consumers are key.
