Cycling is a great way to reduce your carbon footprint and save money on transportation. Research shows that choosing to cycle instead of drive just once a day can reduce an individual's carbon emissions by up to 67%. This is because cycling produces far fewer emissions than driving, with estimates ranging from 5g to 33g of CO2 per mile travelled. In comparison, the average European car emits 271g of CO2 per passenger-km of driving. Increasing the number of trips made by bicycle can also lead to significant fuel savings and reduced greenhouse gas emissions on a larger scale. For example, a moderate increase in annual bicycling is estimated to save 6 to 14 million tons of carbon dioxide.

What You'll Learn
Bikes are 13 times more efficient than cars
Bicycles are a great mode of transport for short commutes. They are not only fun to ride but also a terrific form of exercise. In addition, they are also a more environmentally friendly mode of transport compared to cars.
On average, an American drives 16 miles to work each day. However, nearly 40% of trips taken in the US are two miles or less, which presents a huge opportunity for Americans to opt for bicycles instead of cars. Research from the University of Oxford shows that choosing a bicycle over a car just once a day can reduce the average person's transportation-related emissions by 67%. This is because cycling has a carbon footprint of just 33 grams of CO2 per mile travelled. In contrast, the ECF estimates that for short journeys, the average European car emits 266 grams of CO2 per kilometre, including both tailpipe and well-to-tank emissions. This figure increases to 271 grams of CO2 per passenger kilometre when accounting for the average occupancy of 1.16 passengers per car. This is around 13 times the emissions from cycling, making bicycles 13 times more efficient than cars for short trips.
The environmental benefits of choosing bicycles over cars are significant. Increasing the mode share of trips made by bicycling and walking from 12% to 15% could lead to fuel savings of 3.8 billion gallons a year and reduce greenhouse gas emissions by 33 million tons per year. This is equivalent to replacing 19 million conventional cars with hybrids. In addition, cycling reduces air pollution, which has a positive impact on public health. It is estimated that increasing active transportation can reduce 500 fatalities per million inhabitants in cities such as Delhi and London.
While electric cars pollute much less per kilometre than internal combustion cars, bicycles are still a more efficient choice for short journeys. Electric cars produce around a third of the CO2 per kilometre of an internal combustion car, but they still produce over four times more emissions than bicycles. E-bikes, in particular, are even more efficient than traditional bicycles, with a recent study showing that they are 20 to 35 times more efficient than electric vehicles in terms of miles per kWh. They also produce much lower particulate matter emissions and have a positive impact on community health and traffic congestion.

Cycling reduces carbon footprint
Transportation is a major contributor to carbon emissions, with motor vehicles being the greatest contributor to atmospheric warming. According to NASA, motor vehicles release pollutants and greenhouse gases that promote warming, while emitting few aerosols that counteract it. Therefore, switching from motorized transport to active transport, such as cycling, can significantly reduce an individual's carbon footprint.
According to research from the University of Oxford, choosing to cycle instead of drive just once a day can reduce an individual's transportation-related emissions by 67%. This is because cycling has a much lower carbon footprint than driving, with an estimated 33 grams of CO2 emitted per mile travelled by bike compared to 271 grams of CO2 emitted per passenger-km of driving. This figure includes both tailpipe and well-to-tank emissions, as well as manufacturing emissions.
The benefits of cycling are not limited to the environment; individuals can also save a significant amount of money by choosing to cycle instead of drive. The costs of owning and maintaining a car can add up to thousands of dollars a year, while a bike requires a much smaller upfront investment and minimal maintenance costs.
On a broader scale, increasing the mode share of trips made by bicycle can lead to substantial fuel savings and reduced greenhouse gas emissions. For example, a study found that if 20% of commuters in Milwaukee biked to work, it would save 40,718 tons of carbon dioxide emissions, equivalent to $821,282. Additionally, unnecessary vehicle idling in New York City costs drivers $28 million a year and creates as much pollution as 9 million large trucks travelling from the Bronx to Staten Island.
While cycling may not be feasible for all trips, especially longer journeys, it can still play a crucial role in reducing carbon emissions. Even replacing just one car trip per week with a bicycle trip can make a significant impact on an individual's carbon footprint. Furthermore, with the growing popularity of electric bikes and improvements in battery technology, the range and accessibility of cycling as a mode of transport are expected to increase, making it an even more attractive option for many people.

The environmental benefits of choosing a bike over a car are significant. Research from the University of Oxford shows that cycling instead of driving just once a day can reduce an individual's transportation-related emissions by 67%. This is because cycling has a carbon footprint of only 33 grams of CO2 per mile travelled, compared to 271 grams of CO2 per passenger-km of driving.
The impact of cycling on a larger scale can also be substantial. For example, a NASA analysis found that increasing the mode share of trips made by bicycle from 12% to 15% could lead to fuel savings of 3.8 billion gallons per year and a reduction of 33 million tons of greenhouse gas emissions per year. Similarly, if 20% of commuters in Milwaukee biked to work, it would save 40,718 tons of carbon dioxide emissions, worth $821,282.
While it is important to consider the emissions associated with manufacturing bicycles, the environmental impact of cycling is still significantly lower than that of driving. The European Cyclists' Federation (ECF) estimates that the average bike has a lifespan of 19,200 km, resulting in a lifecycle emission of 0.0018 kg of CO2 per km. This means that the emissions associated with producing a bike are spread out over a significant distance, further reducing the carbon footprint of cycling compared to driving.
In addition to the environmental benefits, cycling also offers health benefits for individuals and populations. Active transportation, such as cycling, has been shown to reduce fatalities and improve health outcomes compared to motorised transport. It is also a more affordable option, with lower costs associated with maintenance, insurance, and payments compared to owning and operating a car.
