# Toluene: Emissions

Borrowing benzene's footprint to estimate toluene's

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

Borrowing benzene's footprint to estimate toluene's 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. Emission intensity 1.50 t CO2e per t range 1.2-1.9 · indicative (basis: Plastics Europe Europe values for benzene 1.86 and p-xylene 1.43, which share the same extraction chain) Global emissions per year 53.0 Mt CO2e per year 2025 · 1.5 t CO2e/t x 35 Mt (indicative)

Per t of toluene, cradle-to-gate. Intensity: Plastics Europe Public LCI Database via Climatiq (analogues; indicative). Global total: derived.

#### Share of footprint by lifecycle phase
 Feedstock 40% Production / process 55% Movement 5%

#### Footprint by lifecycle phase

| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| **Feedstock** | about 0.6 t CO2e per t (indicative) | 40% | Crude extraction and refining |  | indicative |
| **Production / process** | about 0.8 t CO2e per t (indicative) | 55% | Reformer furnaces, extraction steam | Allocation among aromatics drives variance | indicative |
| **Movement** | about 0.05-0.1 t CO2e per t (indicative) | 5% | Tankers and road tankers |  | indicative |
| **Use** | about 3.35 t CO2 per t when burnt in petrol | – | About a quarter of toluene is burnt as gasoline (indicative) | Solvent use releases VOCs that form ozone | stoichiometry (91.3% carbon) |
| **End of life** | not applicable for gasoline and solvent uses; derivatives follow their own end of life | – |  | Spent solvents are recovered or incinerated | n/a |

#### Other environmental impacts

VOC emissions from solvent use contribute to ground-level ozone; neurotoxicity in chronic exposure.

#### Levers to cut emissions

- Solvent recovery and recycling in pharma plants
- Water-based coatings replacing solvent systems
- Refinery furnace electrification and CCS
- Lower petrol demand from EVs frees toluene for chemical use

#### India

India's pharma and agrochemical sector uses large solvent volumes; solvent recovery is a stated efficiency focus of many API makers, but no toluene-specific footprint is published.
 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 |
|---|---|---|---|---|
| **Bio-based toluene from biomass pyrolysis or bio-naphtha reforming** | not published | not published | pilot scale (indicative) | indicative |

 For a climate investor Toluene itself has no clear decarbonisation route beyond refinery abatement. The opportunity is in solvent recovery and substitution in India's pharma and coatings industries, and in water-based paint systems. EV-driven petrol decline will shift toluene toward chemicals, reinforcing integrated aromatics complexes.
