The global and regional pressure to reduce carbon emissions is reaching the paint manufacturing industry in the GCC. Saudi Arabia's Saudi Green Initiative (targeting 50% renewable energy by 2030 and net-zero by 2060) and the UAE's Net Zero 2050 commitment are creating regulatory and commercial pressures on all manufacturing industries — including paint. For coating manufacturers in the UAE and Saudi Arabia, understanding where carbon emissions originate in paint production, and which raw material choices have the greatest impact, is becoming a commercial necessity. This guide provides a practical roadmap for reducing embodied carbon through raw material selection.
Where Carbon Emissions Come From in Paint Manufacturing
| Source | % of Total Carbon Footprint | Reduction Potential |
|---|---|---|
| Raw material production (Scope 3 upstream) | 60–80% | High — raw material selection is the primary lever |
| Manufacturing energy (Scope 1 & 2) | 15–25% | Medium — renewable energy, efficiency improvements |
| Packaging materials | 3–8% | Low-medium — recycled content, lighter formats |
| Logistics and distribution | 3–7% | Low — local sourcing, optimised routing |
| Customer application and use | Negligible for solids | Low |
| End of life / disposal | 1–3% | Low |
Carbon Footprint of Key Paint Raw Materials
| Raw Material | Approx. Carbon Footprint (CO₂e/tonne) | Carbon Reduction Strategy |
|---|---|---|
| TiO2 (chloride process) | 4,000–5,500 | Opaque polymer substitution (20–30% volume); improved dispersion efficiency |
| Epoxy resin (BPA-based) | 4,000–6,000 | Bio-based epoxy (partially); waterborne formulation reduces quantity needed |
| Acrylic emulsion | 2,000–3,500 | Bio-based acrylics; recycled monomer content (emerging) |
| Xylene (solvent) | 3,000–4,000 | Waterborne reformulation eliminates this entirely |
| Calcium carbonate (GCC) | 50–200 | Low carbon — increase usage as TiO2 extender in matt paints |
| Iron oxide pigments | 800–2,000 | Synthetic iron oxides have lower carbon than natural; use minimal loading |
| HDI isocyanate hardener | 6,000–9,000 | Bio-based isocyanates (emerging); waterborne alternatives |
| Polyamide wax / additives | 3,000–5,000 | Minimise loading; bio-based alternatives emerging |
Practical Carbon Reduction Strategies
1. Switch from Solventborne to Waterborne
Eliminating hydrocarbon solvents from a formulation reduces both VOC emissions and the carbon footprint associated with producing those solvents. A typical solventborne alkyd primer containing 30% Xylene can reduce its carbon footprint by 15–25% simply by reformulating as a waterborne system. This also immediately improves SASO/GSO VOC compliance.
2. Optimise TiO2 Usage
TiO2 is simultaneously the highest-performing and highest-carbon pigment in paint. Strategies to reduce TiO2 loading without sacrificing opacity:
- Opaque polymer: Hollow-sphere polymer particles that scatter light. Replace 20–30% of TiO2 volume in high-PVC matt paints with no opacity loss.
- Optimal dispersion: Poorly dispersed TiO2 operates below its efficiency potential. Improving dispersion quality allows the same opacity with 10–15% less TiO2.
- Optimum PVC formulation: TiO2 crowding above CPVC reduces efficiency. Keep PVC below CPVC for maximum TiO2 utilisation.
3. Introduce Bio-Based Raw Materials
As discussed in our companion guide on bio-based resins, introducing castor oil-based polyols (for PU) or soybean oil-modified alkyds can reduce the fossil carbon content of the formulation by 20–40% while maintaining comparable performance.
4. Source Locally Where Possible
Logistics emissions for raw materials are lower when sourced regionally. For GCC manufacturers, sourcing from SABIC (Riyadh), SIPCHEM (Jubail), or UAE-based suppliers reduces transport emissions compared to importing from China or Europe.
5. Prepare an Environmental Product Declaration (EPD)
An EPD documents your product's carbon footprint using standardised methodology. Even the process of preparing an EPD typically identifies 2–3 major carbon hotspots in your formulation that can be targeted for reduction. For Vision 2030 project supply, EPDs are increasingly requested and will likely become mandatory for major project categories by 2027–2028.
