After red meat, conventionally grown coffee is one of the most climate problematic foods we consume. The graphic shows it: Conventional coffee is even worse than chicken and pork! At least per kg. The data comes from a meta-study published in the scientific journal Science.
The data highlights one aspect: cultivation is the most important factor in climate friendliness. What was previously grown on the land (often rainforest) and how the coffee is grown is responsible for around 85% of the greenhouse gas emissions of conventional coffee. To a large extent, this is also true for organic coffee, for which rainforests have had to make way, as for example in Brazil.
The graphic is in general extremely exciting & instructive. In any case, it has already had a strong influence on our personal purchasing decisions as a team!
