From trendy cafes to the cupboards of environmentally conscious households, alternatives to traditional coffee are steadily gaining ground. Driven by health considerations and a growing commitment to sustainability, beverages like chicory, lupin, and roasted barley are becoming mainstream choices for the morning ritual.
The Environmental Cost of a Coffee Habit
The shift is partly fueled by the significant carbon footprint of conventional coffee. According to estimates from the French Environment and Energy Management Agency (ADEME), a standard 250ml cup of filter coffee emits approximately 170 grams of CO2 equivalent. In contrast, the same volume of tea emits only about 10 grams. The high emissions are linked to intensive cultivation practices, including fertilizer and pesticide use, and the deforestation associated with coffee farming.
Chicory: A Classic, Low-Impact Contender
Long popular in France, chicory stands as a leading alternative. Available as an instant powder or for infusion, it boasts a carbon footprint significantly lower than coffee. Data analyzed by consumer magazine Que Choisir and verified by HuffPost indicates that instant chicory emits four times less carbon than filter coffee—roughly 45 grams of CO2 equivalent per 250ml cup. A key advantage is its local production; chicory is extensively cultivated in France, drastically reducing emissions from transportation.
Emerging Contenders: Lupin and Barley
Newer alternatives are also making their mark. Lupin, a legume whose roasted form can be brewed in standard coffee machines, presents a compelling case. ADEME data shows that producing and transporting 1kg of raw lupin seeds emits just 1.1kg of CO2 equivalent. Like chicory, major commercial lupin brands source organic, French-grown beans.
The comparison with imported coffee is stark. A 2020 British study estimated emissions of 11.6kg to 13kg of CO2 equivalent for 1kg of green coffee beans flown from Brazil or Vietnam to the UK. Even sea freight from Costa Rica to Europe results in about 1.77kg of emissions per kilogram.
Roasted barley, a staple in Italy, performs even better in raw form. The production and transport of 1kg of raw barley grain emits a mere 0.6kg of CO2 equivalent. Producers note that while the required volume per cup is similar to coffee, barley’s lower density means using a slightly more heaped spoonful.
A Final Consideration: Mind the Additives
For those truly minimizing their cup’s footprint, what you add matters as much as the base. ADEME notes that cow’s milk carries a carbon footprint far exceeding that of coffee itself. Even soy milk emits about ten times more CO2 equivalent than a cup of tea, underscoring that sustainable choices extend beyond the brew.
