If you want to reduce your personal carbon footprint, you might trade in a car trip for a ride on public transit, or swing by a second-hand clothing store rather than buy fast fashion. You might also take a closer look at what you eat. Food production accounts for one-quarter of global greenhouse gas emissions, and the meat and dairy industries are a big reason why. Hannah Ritchie, an environmental researcher at Our World In Data, an online science publication associated with the University of Oxford, sought to answer that exact question. She found that eating less meat is nearly always a better environmental choice, but the choice of meat and where that meat is sourced from matters. Eating plant-based protein, though, makes the biggest difference—no matter where your beans and tofu come from. Understanding the environmental impacts of our diet can seem overwhelming. But it really comes down to one crucial factor: what we eat.
The production of animal-based foods is associated with higher greenhouse gas GHG emissions than plant-based foods. The objective of this study was to estimate the difference in dietary GHG emissions between self-selected meat-eaters, fish-eaters, vegetarians and vegans in the UK. The diets of 2, vegans, 15, vegetarians, 8, fish-eaters and 29, meat-eaters aged 20—79 were assessed using a validated food frequency questionnaire. Comparable GHG emissions parameters were developed for the underlying food codes using a dataset of GHG emissions for 94 food commodities in the UK, with a weighting for the global warming potential of each component gas. In conclusion, dietary GHG emissions in self-selected meat-eaters are approximately twice as high as those in vegans. It is likely that reductions in meat consumption would lead to reductions in dietary GHG emissions. Production, transport, storage, cooking and wastage of food are substantial contributors to greenhouse gas GHG emissions Committee on Climate Change ; Garnett ; Intergovernmental Panel on Climate Change These GHG emissions include carbon dioxide from fossil fuels used to power farm machinery and to transport, store and cook foods, methane from enteric fermentation in ruminant livestock and nitrous oxide released from tilled and fertilised soils. Both methane and nitrous oxide are many times more potent GHGs than carbon dioxide and the majority of GHG emissions related to food are produced at the agricultural stage Audsley et al. When measured by consumption that is, all GHG emissions related to products consumed in the UK, regardless of where they were produced food is responsible for approximately one fifth of all GHG emissions attributable to the UK Berners-Lee et al. There is considerable variation in the amount of GHG emissions related to different food groups, with animal-based products generally having much greater emissions than plant-based products per unit weight Audsley et al.
