Paints and coatings: Emissions
Why paint's footprint lies almost entirely in raw materials
Why paint's footprint lies almost entirely in raw materials 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 1.80 t CO2e per t range about 0.2-6.4 · weighted mix of decorative emulsions (about 0.2-1.4 t per t at PVC 60-80, Omya) and powder coatings (3.6-6.4 t per t, Tiger Coatings and VdL); solvent-borne industrial in between Global emissions per year 90.0 Mt CO2e per year 2025 · 1.8 t x about 50 Mt (indicative)Per t of paint, cradle-to-gate. Intensity: Omya sustainability toolkit; Tiger Coatings CO2 infosheet (indicative weighting). Global total: derived (indicative).

| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| Feedstock | about 1.7 t CO2e per t | 95% | TiO2 (about 5.7 t CO2e per t), styrene-acrylic dispersion (about 1.5 t), PVAc dispersion (about 1.0 t), solvents; calcium carbonate only about 0.05 t | Omya: raw materials about 85% of a deco paint's total footprint including downstream, so about 98% of cradle-to-gate | Omya sustainability toolkit |
| Production / process | about 0.04 t CO2e per t | 2% | mixing and milling power, emulsion reactors | Scope 1+2 of paint makers is only 1-2% of a deco paint footprint | Omya sustainability toolkit |
| Movement | about 0.05 t CO2e per t | 3% | road distribution of heavy, water-rich product to dealers | indicative | |
| Use | VOCs from solvent-borne paint; oven energy for powder and industrial curing | – | solvent evaporation, curing ovens at 160-200 C | Omya puts downstream Scope 3 at about 10% of a deco paint's footprint; coatings also extend asset life and cool roofs cut cooling load | Omya sustainability toolkit; indicative |
| End of life | small per t; mostly stays on the painted object | – | leftover paint, demolition waste | Paint flakes and road markings are a source of microplastics (indicative) | indicative |
Other environmental impacts
VOCs and ground-level ozone; lead in informal-sector paint in South Asia; biocides; microplastics from weathered paint and road markings.
Levers to cut emissions
- Cut TiO2 use per square metre through better spacing, opaque polymers and extenders; Omya shows 1.40 to 1.00-1.25 t CO2 per t at PVC 60
- Bio-based or bio-attributed binders and solvents
- Low-carbon TiO2 (chloride route on clean power) and recycled-content extenders
- Shift from solvent-borne to water-borne, powder and UV curing
- Renewable heat for curing ovens at industrial customers
India
No national paint footprint is published; India's per capita use (3.5 kg) is a third of the world average, so volume growth will raise emissions unless TiO2 and resin footprints fall.
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 |
|---|---|---|---|---|
| Optimised low-TiO2 decorative formulations | 1.00-1.25 t CO2 per t vs 1.40 reference (PVC 60); 0.23-0.38 vs 0.47 (PVC 80) | often cost-neutral or cheaper (indicative) | commercial | Omya sustainability toolkit |
| Low-carbon powder coatings | 3.64 t CO2e per t for Tiger standard series vs 4.48-6.38 VdL industry worst-case | not published | commercial EPD-backed products | Tiger Coatings CO2 infosheet |
