A study has suggested Caucasian Americans’ diet is contributing significantly more to climate change than the diets of other demographic groups in the country. The study, published in the Journal of Industrial Ecology, said white people contributed the most to greenhouse gas emissions, at 680 kg of carbon dioxide equivalent annually, but added that the Black demographic had the highest contribution to land impacts related to food.
The study set out to “fill in the gaps” in research about how various dietary habits affect the environment along the whole supply chain from land resources to water and energy. It focused on three demographic groups—White, non-Hispanic Back, and Latino—since they represent 92.4 percent of the U.S. population and looked into their eating habits to glean some insight into the relation between these habits and what it calls the food-energy-water nexis.
The study’s authors note that the White population, as portion of the U.S. total, was 61.3 percent, with Latinx—a term the authors of the study call intersectional and non-binary to reflect the latest term trends in social sciences—accounting for 17.8 percent and the Black population accounting for 13.3 percent.
In light of these proportions it’s hardly surprising the White population’s diet was a greater contributor to climate change in terms of greenhouse emissions. However, the study also suggested that the White group’s diet was a greater contributor to climate change because of its higher consumption of what the authors call “environmentally intense” food items.
“Results indicate that Whites tend to consume the highest rates of environmentally intense food items, except for the apples food item, when compared to their Black and Latinx counterparts,” the authors wrote. “Comparing Whites to Latinx, Whites consume significantly more than Latinx for five of the seven environmentally intense food items. This pattern remains the same for beef meat although the difference between Whites and Latinx beef meat is marginally significant.”
