About Carbon Emissions from Transportation

Transport is responsible for approximately 25% of global CO2 emissions. Choosing public transport over private vehicles can significantly reduce your carbon footprint and help combat climate change.

Emission Factors by Transport Type

Different transport modes emit different amounts of greenhouse gases per passenger kilometre:

  • Bus: 68-158 g CO2e per passenger-km (depending on occupancy)
  • Subway/Metro: 27-45 g CO2e per passenger-km
  • Train: 35-60 g CO2e per passenger-km
  • Car (single occupant): 170-250+ g CO2e per km (varies by vehicle type)
  • Bicycle/Walking: Near zero emissions (only considering operation)
Tips for Reducing Your Transport Carbon Footprint
  • Use public transportation whenever possible
  • Combine trips to reduce total distance travelled
  • Consider carpooling to share emissions among multiple passengers
  • For short distances, choose walking or cycling
  • If you must drive, consider a fuel-efficient or electric vehicle
  • Maintain your vehicle properly for optimal fuel efficiency
  • Avoid unnecessary acceleration and braking to save fuel

Understanding the Public Transport Carbon Footprint Calculator

The Public Transport Carbon Footprint Calculator is a helpful tool designed to show how your travel choices impact the environment. It allows you to compare the carbon emissions of various transport options. Whether you take the bus, subway, or drive a car, this calculator makes it easy to see how much carbon dioxide your trips generate. By using this tool, you can make smarter choices that contribute to a healthier planet.

How to Use the Calculator Effectively

Using the carbon footprint calculator is straightforward. You simply enter your trip details, like the distance and how many trips you take each week. You can choose from different transport options, including public transit, cars, and even walking. The calculator then provides a clear comparison of emissions for each option, helping you decide which is the best for your environment.

Key Factors in Calculating Carbon Emissions

  • Distance: The longer the trip, the more emissions are produced.
  • Transport Type: Different modes of transport emit varying amounts of CO2.
  • Occupancy: The number of passengers can greatly affect emissions per person.

Transport Options Available in the Calculator

The calculator covers numerous transport types to give you a comprehensive view. You can select from options such as buses, trains, and electric cars. For those who prefer personal vehicles, there’s space to specify the type of car you drive. The variety allows for a more accurate calculation for your unique situation.

Advanced Features to Enhance Your Experience

Beyond basic calculations, the calculator offers advanced features for a deeper understanding. You can choose how long you want to calculate emissions for—be it weekly, monthly, or yearly. Additionally, you can decide if you want to see carbon equivalents and estimated costs, providing a fuller picture of the impact your transport choices have on the environment and your wallet.

Comparing Transport Methods

One of the standout features of the calculator is its ability to compare different transport methods visually. After entering your data, you’ll see a chart that highlights the emissions of each option. This visual representation makes it easy to see how much better public transport can be compared to driving alone.

Understanding Carbon Emissions from Transport

  • Transport accounts for about 25% of global CO2 emissions.
  • Choosing public transport can significantly reduce your carbon footprint.
  • Different modes of transport have different emission rates per passenger-km.

Tips for Reducing Your Carbon Footprint while Travelling

Reducing your transport carbon footprint is more manageable than you might think. Here are a few simple tips:

  • Use public transport as often as possible.
  • Try to combine trips to limit the total distance travelled.
  • Walking or cycling for short distances is a great choice.
By applying these tips alongside the calculator, you can contribute to a healthier planet and save on travel costs too!
