Schwalbe Green Marathon Report

It has little place on mountain bikes, but on many everyday bikes: The Schwalbe Marathon is a classic, which is also available in a green version. Schwalbe now explains exactly how much C02 is saved, for example.

According to Schwalbe, it is the world's first bicycle tire with a closed material cycle - now the German tire expert has presented a detailed Life Cycle Assessment (LCA) to quantify the environmental impact of the Green Marathon.

The result: With 1.43kg of so-called CO2 equivalents (CO2eq), the Green Marathon saves a total of 41% CO2eq compared to its predecessor model. The Marathon from 2010 already had a lower CO2eq footprint than other bicycle tires thanks to the use of recycled materials, including in the puncture protection.

The Product Carbon Foot- print (PCF) calculated with the life cycle assessment provides a key finding: the majority of emissions, 62% in total, are attributable to raw materials. Around a third is caused by energy consumption during production and only just under 3.5% is caused by transportation. This underlines the importance of research into raw materials and materials for reducing environmental impacts. Schwalbe has been working intensively on the ecological material optimization of all tires and tubes since 2013.
