Bus & Coach Carbon Calculator
Our bus and coach carbon footprint calculator is a tool designed to calculate the carbon dioxide (CO2) emissions associated with bus and coach travel. This can help individuals, companies, and policymakers to understand the environmental impact of these forms of transportation and make informed decisions about travel and transportation policies.
Note: This calculator uses Passenger km factors which are used when single passengers are travelling by means of mass transport (such as by coach or bus ) and the aim is to calculate emissions on a single-person basis, not account for the whole vehicle. If multiple coaches are being used for the same journey then the total number of passengers can be used rather than calculating each bus or coach on an individual basis.
Carbon Footprint Facts about your Bus or Coach Journey
Emission Comparison: The average bus in the UK emits about 75g of CO2 per passenger-kilometre, compared to 158g for cars. This means that bus travel can cut per-passenger CO2 emissions by more than half compared to car travel.
Electric Buses: Electric buses produce zero tailpipe emissions, and can therefore significantly reduce CO2 emissions from public transport, especially as the electricity grid becomes less carbon-intensive. As of 2020, there were about 500 electric buses in service in the UK.
Lifecycle Emissions: Over its lifecycle, a diesel bus emits around 1,700 tonnes of CO2, while an electric bus emits around 1,100 tonnes, including manufacturing and fuel production emissions. This represents a reduction of about 35%.
