0.24 to 0.39 Mton CO₂-eq per year. The environmental impact of the bicycle product group, extrapolated from several life-cycle analyses, is estimated at 0.24 to 0.39 Mton CO₂-eq per year. The Quickscan Circular Bicycle by New Economy reports this. The environmental impact and lifespan of bicycles are rarely mapped systematically.
Steering on lifespan and repairability reduces the impact of bicycles most. This is relevant for bicycle manufacturers, designers and organisations in circular mobility.
