While global coffee consumption has been increasing steadily for almost 30 years, the demand has led to various ways of preparing coffee as well, including the creation of coffee capsules. The popularity of these capsules has divided the public opinion because this method of preparation, which uses single-use individual packaging, is harmful to the environment.
The study noted in recent articles take aim at the carbon footprint from preparing coffee.
One post begins with “Before you can enjoy a cup of coffee, it goes through several steps, starting from the agricultural production of the coffee beans, their transport, the roasting and grinding of the beans, right up to the heating of the water for the coffee and the washing of the cups it is poured in.
“These steps, common to all modes of coffee preparation, consume resources and emit greenhouse gases (GHG).”
The study focused on the carbon footprint of coffee of four methods of preparing 280 millilitres of coffee, namely:
1) Traditional filter coffee (25 grams of coffee)
2) Encapsulated filter coffee (14 grams of coffee)
3) Brewed coffee (French press) (17 grams of coffee)
4) Soluble coffee (12 grams of coffee), also known as instant coffee
“Our analysis clearly showed that traditional filter coffee has the highest carbon footprint, mainly because a greater quantity of coffee powder is used to produce the amount of coffee. This process also consumes more electricity to heat the water and keep it warm,” the research states.
The conclusion is the same as outrage against the dairy and meat industries: “Limiting your contribution to climate change requires an adapted diet, and coffee is no exception. Choosing a mode of coffee preparation that emits less GHGs and moderating your consumption are part of the solution.”
