Bicycles are an effective way to reduce pollution and combat climate change. Evidence suggests that cycling reduces air pollution and greenhouse gas emissions, with a significant shift towards bicycles for trips under 16km having the potential to decrease emissions considerably. NASA found that increasing the share of trips made by bicycle from 12% to 15% could lead to fuel savings of 3.8 billion gallons annually and a reduction of 33 million tons of greenhouse gas emissions. Furthermore, cycling 16 miles to work instead of driving can reduce an individual's carbon emissions by 67%. In Philadelphia, cyclists save 47,450 tons of CO2 emissions annually, and in New York, a similar shift would be equivalent to planting a forest 1.3 times the size of Manhattan.

Bicycles have a carbon footprint of 33 grams of CO2 per mile, 30 times less than fossil fuel cars
Bicycles are a great way to reduce your carbon footprint and save on pollution. Research from the University of Oxford shows that choosing to cycle instead of driving just once a day can reduce an individual's transport emissions by 67%. This is because cycling produces a carbon footprint of only 33 grams of CO2 per mile travelled, which is significantly lower than that of a fossil fuel car.
To put this into perspective, a bicycle's carbon footprint is 30 times lower than that of a car powered by fossil fuels. This means that if you were to replace even one car journey with a bicycle ride, you would be making a substantial difference in reducing your carbon emissions. For example, if 20% of commuters in Milwaukee biked to work, it would save 40,718 tons of carbon dioxide emissions, valued at $821,282. Similarly, in Philadelphia, cyclists ride 260,000 miles daily, saving 47,450 tons of CO2 from being emitted by cars each year.
The benefits of cycling extend beyond just carbon dioxide emissions. A shift towards active transportation, such as cycling, can help address issues with current transport patterns, including emissions of air pollutants, greenhouse gases, and noise. It can also reduce traffic injuries and create more opportunities for physical activity. In addition, the production of cars is a significant contributor to carbon emissions, with the average production of a car accounting for 42 grams of CO2 emissions per kilometer driven. By choosing to cycle instead of drive, you are not only reducing emissions during your journey but also avoiding the carbon-intensive process of car manufacturing.
It is worth noting that cycling does have some carbon costs. The manufacturing of bicycles and the food required to power cycling trips contribute to a cyclist's carbon footprint. However, these costs are significantly lower than those associated with driving. Additionally, the rebound effect, where increased efficiency leads to more polluting activities, can impact the overall carbon savings of cycling. Nevertheless, the potential for decreasing emissions through cycling is considerable, and it is an important tool in mitigating climate change.
