Comparing use-phase
CO₂ footprints
The current carbon footprint of Twaron® is 8.7 kg CO₂eq/kg, which is significantly lower than that of competing aramid materials. Our goal is to achieve 0 kg CO₂eq/kg by 2050.
Twaron® vs. Rayon
While Rayon may have a lower carbon footprint per kilogram, a single layer of Twaron® achieves the required reinforcement performance where two layers of Rayon are needed. This efficiency results in a reduced CO₂ footprint for the raw materials in the tire. Using our TÜV-certified Customer Benefit Model, we compared a two-layer Rayon carcass tire to a single-layer Twaron® carcass tire. The Twaron® carcass tire is about 1 kg lighter, contributing to CO₂ savings during the use phase. For a set of four tires on a single vehicle, this difference amounts to a reduction of 66 kg CO₂ equivalent over the tire lifetime.

Twaron® vs. PET HMLS
While polyester may have a lower carbon footprint per kilogram, a single layer of Twaron® achieves the required reinforcement performance where two layers of polyester are needed. This efficiency results in a reduced CO₂ footprint for the raw materials in the tire. Using our TÜV-certified Customer Benefit Model, we compared a two-layer polyester carcass tire to a single-layer Twaron® carcass tire. The Twaron® carcass tire is more than 1 kg lighter, contributing to CO₂ savings during the use phase. For a set of four tires on a single vehicle, this difference amounts to a reduction of 53 kg CO₂ equivalent over the tire lifetime.
