Environmental Sustainability

Bicycles are often praised for being energy efficient and non-polluting.

The amount of energy required to produce a bicycle is tiny compared to many other forms of transport. A 7.2kg road bicycle with a carbon frame uses 11,546,658,000 Joules of energy during its production compared to 118,284,466,000 for a ‘generic car’. Variations exist based on bicycle type and other external factors, but even taking this into consideration, the bicycle has a low embodied energy. Additionally, bicycle lane construction is less energy intensive than roads for automobiles, requiring a smaller amount of space and minimal foundations.

A bicycle’s environmental sustainability is about more than just low embodied energy. If enough people switch from polluting transport modes to a bicycle – a zero emission form of transport when in use – there is potential for reduced carbon emissions and improved air quality in our cities.

Pollution is about more than just emissions. Noise levels in cities can also be considered a pollutant, with associated long term health risks. Some cities are even highlighting noise pollution in their sustainability agendas.

Sadly, bicycle networks and bicycles themselves don’t have so much influence in a city environmental changes. The analysis of urban air quality is complex, affected by local factors such as weather, geography and industry – something bicycle networks have no control over. In fact, cities will always use energy, emit carbon, and make noise. However, a city that depends on bicycles more than other automated forms of transportation will require less energy, emit less carbon, and make less noise.

Moreover titanium is biocompatible, recyclable, harmless for flora and fauna. Thanks to its characteristic corrosion resistence, it’s not subject to loss of metal and other substances, avoiding water pollution and energy consumption for repairs. For these reasons is used to build oil platforms, to produce human prothesis, etc.
