# Pepper & spices: Emissions

Why pepper's footprint remains unmeasured

Source page: https://www.materialinsights.org/commodities/spices/emissions/

Why pepper's footprint remains unmeasured 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.

Per t of dried black pepper at farm or exporter gate (cradle-to-gate). Intensity: not available. Global total: not available.

#### Footprint by lifecycle phase

| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| **Extraction** | not published | – | nitrogen fertiliser and field N2O on intensive post-trained pepper in Vietnam and Brazil; very low inputs on Indian homestead pepper | IPCC default: about 1% of applied nitrogen is emitted as N2O-N. Indian shade-grown pepper also stores carbon in its support trees. | IPCC 2019 Refinement (indicative); FAOSTAT 2024 |
| **Refining / processing** | not published | – | sun-drying (near zero fossil energy), heated curing houses for cardamom (wood), steam sterilisation, grinding, solvent extraction of oleoresin | Cardamom curing with fuelwood can be significant locally. | content_v2 spices chain |
| **Movement** | about 0.15-0.3 t CO2/t Ho Chi Minh City to Rotterdam by container (calculated, indicative) | – | container shipping | About 16,700 km at 10-20 g CO2 per t-km. | calculated; IMO 2020 order of magnitude (indicative) |
| **Usage** | not applicable | – | used in small amounts in cooking | Cooking energy is attributed to the dish, not the spice. | qualitative |
| **Recycling / end of life** | not applicable | – | no recycling; spent meal from oleoresin extraction is used as feed or fuel |  | content_v2 spices methods |

#### Other environmental impacts

Pesticide residues and aflatoxin are the main environmental and safety issues in trade. Intensive Vietnamese pepper uses heavy fertiliser and irrigation from groundwater in the Central Highlands.

#### Levers to cut emissions

- Keep agroforestry and homestead systems, which store carbon in shade and support trees
- Calibrate fertiliser on intensive pepper to cut N2O
- Solar dryers and efficient cardamom curing houses to replace fuelwood
- Steam sterilisation with efficient boilers

#### India

Most Indian pepper and cardamom grows under shade in Kerala and Karnataka homesteads with few inputs and is sun-dried, so its farm footprint is likely low, though no published figure was found. Cardamom curing houses in Idukki burn fuelwood (indicative).
 Emission figures are indicative global averages from the life-cycle studies named; actual footprints vary widely by site, energy mix and method.
