# Reagents and high-purity lab chemicals: Emissions

Glass, cold chains and air freight multiply the footprint

Source page: https://www.materialinsights.org/chemicals/lab_reagents/emissions/

What this tab covers The greenhouse-gas footprint per tonne, split by lifecycle phase (feedstock, production, movement, use, end of life), the global total, other environmental impacts, levers and low-carbon routes, India's position, and where the investment opportunity lies.

Per kg of packed reagent, cradle-to-gate. Intensity: indicative. Global total: not published.

#### Share of footprint by lifecycle phase
 Feedstock 25% Production / process 45% Movement 30%

#### Footprint by lifecycle phase

| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| **Feedstock** | as for the bulk chemical (see chemical tiles) | 25% | bulk solvents, acids and salts |  | indicative split |
| **Production / process** | not published | 45% | repeated distillation and purification, cleanrooms, QC testing, glass and plastic packaging | packaging can outweigh the chemical for small packs (indicative) | indicative split |
| **Movement** | not published | 30% | air freight, couriers and dry ice cold chain |  | indicative split |
| **Use** | small | – | fume hood energy and solvent evaporation in labs | labs use three to ten times more energy per square metre than offices (indicative) | indicative |
| **End of life** | not published | – | incineration of spent solvents and hazardous lab waste |  | indicative |

#### Other environmental impacts

Hazardous waste from labs, solvent emissions, plastic consumables and packaging waste.

#### Levers to cut emissions

- Solvent recycling and take-back programmes
- Greener solvent substitutions (e.g. ethanol for acetonitrile in some HPLC methods)
- Larger packs and bulk delivery
- Sea instead of air freight; less dry ice
- Miniaturised and automated assays

#### India

Indian reagent makers are small and private and do not publish emissions in the sources used.
 Emission figures are indicative global averages from the life-cycle studies named; actual footprints vary widely by site, energy mix and method.

#### Low-carbon routes

| Route | Intensity | Cost premium | Status | Source |
|---|---|---|---|---|
| **Lab solvent recovery and reuse** | avoids new solvent production and incineration (indicative) | equipment and validation | used in some pharma QC labs (indicative) | indicative |

 For a climate investor Small in carbon terms, so the angle is import substitution and green lab practice: Indian makers moving up to LC-MS, biochemical and certified reference grades, and lab solvent recovery services. What has to be true: accreditation (ISO 17034), consistent lot quality and distribution reach.
