Coffee Carbon Footprint Calculator

Your details

Each brew method uses a different amount of ground coffee and energy, which affects its carbon footprint.
Dairy cow milk has by far the largest carbon footprint of any milk type. Plant-based milks are 2-5x lower.
Disposable cups add roughly 11 g CO2e per cup due to paper, plastic lining, and waste. A reusable cup offsets this after about 15 uses.
Average number of cups you drink each day. Fractions are fine (e.g. 0.5 for one every other day).

Your filter coffee black produces 21 g CO2e per cup, or 15.3 kg per year.

  • Drinking black coffee keeps the milk-related footprint at zero. Adding oat milk instead of cow milk is the biggest single lever if you do add dairy.
  • Your annual coffee footprint of 15.3 kg CO2e is equivalent to driving about 80 km in an average petrol car.
  • A single mature tree would need about 266 days to absorb your annual coffee emissions.

Next stepYour coffee footprint is already on the lower side. Carrying a reusable cup and choosing sustainably certified beans are the next steps.
