In the long list of challenges that our cities and their inhabitants face, transportation ranks near the top.
To start, transportation is one of the largest emitters of greenhouse gases, contributing a total of 14–22% of global CO2 emissions; of those, cars alone account for 40% of transport CO2 emissions. Project Drawdown estimates that new bicycle infrastructure and electric bike usage together have the potential of reducing 3.9–10.7 GtCO2 between now and 2050. While that’s a far cry from the total number of emissions that need to be curbed or sequestered to reach our climate goals, cycling remains a powerful and accessible lever in our “carbon solutions system” that could ultimately account for 10–20% of all alternative transportation reductions.
Beyond carbon emissions, the continued dominance of petrol and diesel cars presents other serious public health concerns. These include air pollution (now the fourth-largest killer in the world) and noise pollution (40% of the EU population is exposed to higher levels of road traffic noise than recommended), which lead to serious mental health challenges.
