Environmental sustainability is an essential aspect of Pacific Western Transportation’s corporate culture. In an important way, the passenger transport business is inherently sustainable. As a leading provider of transportation services in Canada, PWT is at the forefront of the global effort to get cars off the road in favor of more efficient modes of transit. Using innovative thinking and state-of-the-art technology, PWT is focused on continually reducing emissions and minimizing the footprint of our operations.
Bus versus cars
Compared to bus travel, travel by car produces 3x more global warming gases; 1.6x more common air pollution; 4.2x more toxic air pollution; 1.2x more water habitat alteration; 4.4x more land habitat alteration; 1.8x more common water pollution; 2.7x more toxic water pollution

How do you compare CO2 emissions for car journeys and public transport journeys?
We try to give you an overall feel for what the difference in CO2 emissions produced per traveller would be.
If the journey you have chosen is by car, we calculate the emissions for that journey following the actual route to be taken, if you then select a public transport comparison we estimate the emissions based on travelling the same straight line distance as the car using the different types of public transport. This is for comparison only and there may or may not be viable public transport links between the original car journey locations. If you want to actually travel by public transport use the appropriate planer to find your travel options.
Similarly if we have planned you an actual public transport journey, when you ask for a comparison we estimate both car and other types of public transport emissions based on travelling the same straight line distance as the selected public transport journey. For the car we estimate how much fuel would be used and hence emissions generated. In this case we assume you would be travelling in a medium sized petrol car travelling on a combination of urban and interurban roads, with average congestion (resulting in the emissions being increased by 1.03 compared with the unrestricted values).
We compare the predicted CO2 emissions produced for a car journey with a specified number of occupants with an estimate of the total CO2 emissions that would be produced for each traveller on one or more types of public transport.
However, a car and public transport are different. In absolute terms of reducing CO2 it is always better to use a scheduled public transport service. This is because when you use a car the result is an extra journey is made and extra CO2 is emitted into the atmosphere. On the other hand, when you use public transport journey by bus, coach, plane or train the journey is always scheduled and would take place whether or not you travelled. So in real terms there is no additional CO2 emitted.
What assumptions do you make about bus and coach journeys when calculating emissions?
To determine whether emissions for either a bus or a coach are shown we first estimate the journey distance.
We assume you will be travelling by bus on short journeys of less than 30KM. So on short journeys we only show the predicted CO2 emissions for a bus.
On the other hand, if we estimate that the journey distance is longer than 30KM we assume you will be travelling by coach. So on longer journeys we only show the CO2 predicted emissions for a coach.
To calculate bus emissions we use a factor based on the average bus miles per gallon and number of passengers carried and to calculate coach emissions we use a factor based on the average coach miles per gallon and number of passengers carried
Environmental Fact Sheet
- Catching public transport is one of the most environmentally friendly forms of transport (see table below).
(The above graph was sourced from the former Australian Greenhouse Office.)
- Even driving a fuel-efficient small car produces several times more greenhouse gas emissions than catching an existing bus service.
- Each bus trip has the potential to take around 50 cars off the road.
