Oranges & juice: Emissions
The carbon behind a carton of juice
What this tab covers The greenhouse-gas footprint of the commodity at a global level, split by lifecycle phase: extraction (or farming), refining and processing, movement, usage, and recycling or end of life. Intensities are per unit of product; the global total combines intensity with world output. Also covers other environmental impacts and the main levers to cut emissions. Emission intensity 0.90 kg CO2e per litre range fresh citrus fruit about 0.39 kg CO2e per kg (cradle-to-retail) · 1.7 kg CO2e per half-gallon (1.89 L) carton of Tropicana Pure Premium, certified by the Carbon Trust; fresh citrus from a global meta-analysis Global emissions per year 26.0 Mt CO2e per year 2024 · 67.2 Mt of oranges x 0.39 kg CO2e/kg fresh citrus (calculated, indicative)Per litre of not-from-concentrate orange juice at retail (cradle-to-shelf, packaged); fresh fruit given for comparison. Intensity: PepsiCo/Carbon Trust 2009 (indicative); Poore & Nemecek 2018 via OWID (indicative). Global total: FAOSTAT 2024; Poore & Nemecek 2018.
Share of footprint by lifecycle phase
Extraction 60% Refining / processing 40%Footprint by lifecycle phase
| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| Extraction | about 0.5 kg CO2e/L (calculated from about 60% share) | 60% | nitrogen fertiliser manufacture and field N2O, grove diesel, irrigation | Growing was the largest share in the Tropicana study, mostly from fertiliser. | PepsiCo/Carbon Trust 2009 (indicative) |
| Refining / processing | about 0.4 kg CO2e/L, including packaging and distribution | 40% | extraction, pasteurisation, evaporators for FCOJ, chilled or frozen storage, cartons | The published summary does not split processing, packaging and transport; all are included here. | PepsiCo/Carbon Trust 2009 (indicative) |
| Movement | included in the processing share above | – | bulk juice tankers Santos to Europe (about 10,000 km), refrigerated trucking | Concentrating to 65 Brix cuts volume shipped several-fold; NFC must be kept chilled. | content_v2 orange chain |
| Usage | small | – | home refrigeration; food waste | Not applicable as direct emissions. | qualitative |
| Recycling / end of life | by-products offset some impact | – | peel and pulp go to cattle-feed pellets, peel oil and d-limonene; cartons | Pulp pellets replace other feed; cartons are hard to recycle where collection is weak. | content_v2 orange methods |
Other environmental impacts
Irrigation water in Egypt, Spain and South Africa. Heavy insecticide use against the psyllid that spreads citrus greening.
Levers to cut emissions
- Cut nitrogen use and switch to low-carbon fertiliser, the largest source (about 60%)
- Efficient evaporators and heat recovery in juice plants
- Ship concentrate rather than NFC where taste allows, to cut volume and refrigeration
- Use peel and pulp fully as feed, oil and biogas
India
India grows 3.85 Mt of oranges (mostly Nagpur mandarins) on 0.24 Mha and eats almost all of them fresh, so processing emissions are small (FAOSTAT 2024). Low yields of 16 t/ha and post-harvest losses in a weak cold chain raise emissions per kg eaten (indicative).
Emission figures are indicative global averages from the life-cycle studies named; actual footprints vary widely by site, energy mix and method.
