During the Christmas season, CO2 emissions from food can significantly increase. Traditional meals, especially those high in meat and dairy, contribute heavily to greenhouse gas emissions. Research indicates that beef has a much larger carbon footprint compared to plant-based options, while sustainable choices like local game and farmed carp can reduce impact. Additionally, selecting regionally grown vegetables and low-emission sweets and drinks can further lower emissions. Emphasizing gradual dietary shifts can lead to a more sustainable future.
Reducing CO2 Emissions During the Festive Season
During the Christmas season, the carbon dioxide emissions resulting from our food consumption can double compared to a typical day. However, with some mindful choices, we can enjoy our holiday meals while also being kind to the planet.
Understanding the Climate Impact of Holiday Dishes
Traditional Christmas meals often rely heavily on animal products such as potato salad with sausages, goose, and cheese fondue. According to Nils Rettenmaier from the Institute for Energy and Environmental Research (ifeu) in Heidelberg, meat and dairy products contribute to nearly two-thirds of all diet-related greenhouse gas emissions.
Not all festive dishes are equal in their environmental impact. Research by Marco Springmann from the University of Oxford highlights that beef can produce up to a hundred times more CO2 emissions than plant-based options, with pork and cheese also having a significantly higher impact.
For example, meat fondue, particularly when using beef, ranks high on the emissions scale. In contrast, the CO2 footprint of pork and poultry is about half that of beef, with cheese also being a considerable contributor. Instead of traditional meats, Rettenmaier suggests opting for game from local hunters as a more sustainable choice.
Among fish options, carp emerges as a favorable choice, boasting a better CO2 balance compared to many other seafood options.
Choosing Sustainable Fish and Vegetables
At least 16 percent of Germans include fish in their Christmas meals. Generally, fish has a carbon footprint similar to chicken, though it varies by species. Springmann cautions against choosing salmon for holiday meals due to its high feed requirements, which significantly increases energy consumption during production.
Conversely, farmed carp from Germany is a sustainable and eco-friendly choice, exhibiting a lower CO2 footprint than chicken. Mussels, favored in Spanish holiday traditions, also contribute minimally to greenhouse gas emissions due to their sustainable farming practices.
When selecting side dishes, it’s essential to consider their origin. Regional produce doesn’t always guarantee a better CO2 balance. For instance, tomatoes grown in Spain may be more efficient than locally grown winter tomatoes that require heating. Similarly, potatoes are more climate-friendly than rice, as rice farming generates harmful methane emissions. Pasta is another low-emission alternative.
Indulging in Sweets and Drinks Wisely
Sweets are a beloved part of Christmas, from cookies to gingerbread. Interestingly, sugar, a common ingredient, has a relatively low climate impact, emitting about 0.5 to 0.7 kg of CO2 per kg compared to many other foods. This is due to the lower emissions associated with sugar beet and sugar cane cultivation.
In terms of beverages, enjoying sparkling wines or white wines with your meals can be done with minimal environmental impact. The grape-based drinks have a low CO2 footprint, even when imported, as transportation accounts for only a small fraction of total emissions.
Ultimately, it’s important to remember that the focus should not be solely on individual meals but rather on a gradual shift towards reducing animal product consumption over time. Every small change contributes to a more sustainable future, and the overall balance matters more than strict adherence to dietary restrictions on specific days.
