# Flame retardants: Emissions

Why halogen-free mineral retardants carry a lighter footprint

Source page: https://www.materialinsights.org/chemicals/flame_retardants/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. Emission intensity 2.40 t CO2e per t range about 0.5-6 · indicative weighted average: ATH about 0.7 t (Bayer process hydrate, no calcination) at 38% share, halogenated and phosphorus FRs about 3.5 t at 62% Global emissions per year 5.50 Mt CO2e per year 2023 · 2.3 Mt x 2.4 t CO2e/t (indicative)

Per t of flame retardant, cradle-to-gate. Intensity: indicative (basis: Ceresana shares; bromine tile 0.5-2 t CO2e per t Br2). Global total: indicative.

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

#### Footprint by lifecycle phase

| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| **Feedstock** | about 1.3 t (indicative) | 55% | bauxite refining, bromine extraction, phosphorus furnaces, antimony smelting | Share indicative. | indicative |
| **Production / process** | about 1 t (indicative) | 40% | bromination and synthesis energy; milling and drying | Share indicative. | indicative |
| **Movement** | about 0.1 t (indicative) | 5% | sea freight | Share indicative. | indicative |
| **Use** | net benefit in avoided fires | – | fewer fires and less material burned; some FRs leach into dust | Halogenated FRs raise smoke toxicity and dioxin formation when they do burn. | indicative |
| **End of life** | not published | – | POP-containing plastics must be destroyed, not recycled | Legacy BFRs in e-waste and XPS foam block recycling. | indicative |

#### Other environmental impacts

Persistence, bioaccumulation and toxicity of legacy BFRs and CPs; dioxins and furans from burning e-waste.

#### Levers to cut emissions

- Shift to mineral and phosphorus FRs with lower toxicity
- Polymeric FRs that do not migrate
- Low-carbon power at bromine and phosphorus plants
- Sorting and destruction of POP-containing plastics to unlock recycling of the rest

#### India

India's FR use grows with cables, data centres and building codes; most is imported, and no national footprint data was found.
 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 |
|---|---|---|---|---|
| **Halogen-free systems (ATH, MDH, phosphinates) in cables and electronics** | ATH about 0.7 t CO2e/t (indicative) | higher loading or higher price per kg | mainstream in EU low-smoke cables | indicative |

 For a climate investor The opportunity is safer, halogen-free FRs for cables, EV batteries and building products, and e-waste plastic sorting that separates POP-containing material. India has bromine and alumina feedstock but little FR synthesis, so local capacity behind growing demand is a gap, provided it targets chemistries not facing restriction.
