The carbon footprint of frozen cauliflower
Frozen cauliflower emits about 0.707 kg CO₂e per kg. Below is where that figure actually comes from — every stage of the chain, not a single headline number.
- Processing
- 0.372 kg
- 53%
- Turning the raw product into food: milling, refining, slaughter, curing.
- Transport
- 0.317 kg
- 45%
- Moving it from farm to processor to shop.
- Packaging
- 0.018 kg
- 3%
- Producing the packaging it reaches you in.
How it is grown changes the number by 49%
These are 5 separately assessed production systems for the same product. Emissions are farm-gate — the part the grower controls — and range from 0.169 to 0.329 kg CO₂e. A label on a shelf almost never tells you which one you are holding.

Common questions
- How much CO2 does frozen cauliflower produce?
- About 0.707 kg CO₂e per kg, measured across the supply chain. That is roughly the same as driving 4 km in an average petrol car.
- What drives the footprint of frozen cauliflower?
- Processing is the largest contributor at 0.372 kg CO₂e, about 53% of the total. Transport is only 0.317 kg — which is why what you eat matters far more than how far it travelled.
- Does how frozen cauliflower is produced change its footprint?
- Yes, substantially. Across 5 production methods in this dataset the farm-gate emissions range from 0.169 to 0.329 kg CO₂e — a difference of 49%.
- Where does this data come from?
- The WRAP UK Food & Drink Emission Factor Database v2.0, which aggregates peer-reviewed life-cycle assessments. This product's figures come from Frankowska et al..
Figures from the WRAP UK Food & Drink Emission Factor Database v2.0, which aggregates published life-cycle assessments; this product's data originates from Frankowska et al., for UK. Real values vary by farm, region and method — treat these as the shape of the problem, not a measurement of any one item on your shelf.
