The daily commute to work is an integral part of everyday life for millions of people - and at the same time a decisive lever for more climate protection. While cars and even public transport continue to consume resources and cause emissions, travelling by bike offers an almost emission-free alternative. Anyone who switches to cycling makes a direct contribution to environmental sustainability - with every single kilometre.
Small footprint on two wheels
Leaving aside the production of the bike itself, the most obvious advantage of commuting by bike is the complete avoidance of direct CO₂ emissions. While an average car emits around 120 to 180 grams of CO₂ per kilometre, the bicycle remains completely emission-free during operation. Even in comparison to the railway, which is often considered environmentally friendly, the bicycle performs better: although trains are significantly more efficient than cars, they also require energy - often from sources that are not completely renewable.
In addition to emissions, resource consumption also plays a decisive role. Manufacturing, maintaining and operating a car requires large quantities of raw materials such as steel, aluminium, plastics and rare earths. Bicycles, on the other hand, are significantly more material-efficient and durable. Their production causes only a fraction of the environmental impact of a car - and the infrastructure they require is also much more resource-efficient.
The chronic unreliability of Deutsche Bahn and the daily traffic chaos in the south of Munich have meant that I now commute to work by bike four times a week. The physical investment for the 32 kilometres one way is enormous, but as even the train between home and work runs on diesel engines, the ecological footprint is significantly smaller. - Jan Timmermann, BIKE editor
Less sealing, noise and particulate matter
Cars need space - and lots of it. Roads, car parks and garages contribute to land sealing, which in turn has a negative impact on ecosystems, the water balance and biodiversity. In comparison, bicycles require only minimal infrastructure: narrow cycle paths and small parking spaces are sufficient. More people on bikes therefore means less need for sealed surfaces in the long term.
In addition to CO₂, cars contribute significantly to air pollution and noise pollution in cities. Particulate matter is not only caused by exhaust fumes, but also by tyre and brake wear. In comparison, bicycles cause neither significant noise nor relevant pollutant emissions. An increasing number of cycle commuters therefore directly improves the quality of life in urban areas.
Energy efficiency in its purest form
The bicycle is one of the most efficient means of transport of all. The energy required per kilometre travelled is minimal - and is largely covered by human muscle power. Even e-bikes, which require additional energy, consume only a fraction of the power of motorised vehicles due to their still relatively low mass and therefore high efficiency.
Switching to a bicycle may seem small on an individual level, but in total it has an enormous impact. Every kilometre avoided by car reduces emissions, saves resources and protects the environment. At the same time, cities benefit from less traffic, better air and less noise pollution. Commuting by bike is therefore far more than just an alternative - it is a key building block for sustainable mobility in the future. Anyone who pedals regularly is not only travelling to work, but also making a contribution towards a more environmentally friendly world.
Conclusion
I myself commute to work by bike mainly out of sporting motivation and for reasons of efficiency. However, the sustainability aspect is a welcome side effect. Last year, I emitted around one tonne less CO₂ than if I had driven my car. Of course, everything is relative: my job also requires air travel and a single trip to the USA blows over 3.5 tonnes of CO₂ into the atmosphere. - Jan Timmermann, BIKE editor
