A Green Choice for Transportation
Go with Natural Gas began as a collaborative industry-government initiative, supported with funding from Natural Resources Canada. Canada’s natural gas vehicle industry continues to champion this initiative, encouraging greater use of natural gas in the country’s transportation sector. The Go with Natural Gas initiative provides comprehensive information on transitioning to natural gas, highlighting its benefits in lowering emissions and reducing fleet operating costs, making it a go-to resource for Canadian fleets.
As part of a broader education and outreach program, Go with Natural Gas aims to build capacity for the transition to natural gas vehicles across Canada.
Go with Natural Gas – a smart choice for transportation!
Natural gas offers the most accessible and cost-effective emissions reduction opportunity for medium- and heavy-duty transportation. It's a practical choice for both on-road and marine vehicles.
Building on existing internal combustion technologies, natural gas has been used successfully as a transportation fuel for over 30 years, proving its reliability and effectiveness.
Natural gas is an abundant energy source in Canada, efficiently transported via an extensive delivery system, making it a readily available fuel for transportation needs.
Compared to petroleum-based fuels, natural gas has a lower emissions profile. It produces fewer trace constituents, little or no Sox, minimal particulate matter, and significantly less NOx, along with 25% lower greenhouse gas emissions.
Natural gas is recognized as an end-use fuel switching option under the Federal Government’s Clean Fuel Regulation, supporting Canada's transition to cleaner energy.
Refueling at an existing public CNG station may be a viable option at the early stages of switching to natural gas. If a public station is to be used, fill time and site access are important considerations.
Private onsite CNG or LNG refueling stations may be suitable if the fleet’s total natural gas fuel volume is sufficient. A general rule of thumb is that typically 20 medium or heavy vehicles are needed in order to consider a private onsite station.
Another refueling option may involve accessing a nearby private station owned by another fleet.

CNG is natural gas that is:
Fleets that choose natural gas have a range of refueling station options and a choice of service providers for vehicle refueling. Stations dispensing CNG can be designed as fast fill stations capable of matching the filling times of liquid fuels or time fill stations that refuel all vehicles simultaneously with refueling typically taking place overnight in the fleet yard.
LNG stations refuel vehicles in times similar to diesel station refueling. An LNG refueling station must have a local supply of fuel. Given that LNG is delivered by tanker truck, delivery cost and proximity of the LNG production facility are important considerations. At present, there are five LNG production facilities in Canada that can supply LNG for fleets.
These facilities are located in Montréal (QC), Calgary (AB), Delta (BC), Ladysmith (BC), and Hagar (ON).
LNG is a natural gas that is:
Public transit and refuse fleets have led the deployment of natural gas-powered vehicles in Canada with heavy-duty truck applications poised to follow suit as new engine/vehicle configurations hit the market.
The Federal Clean Fuel Standard outlines default values for greenhouse gas emissions (GHG) reductions resulting from the use of natural gas. These show the potential for a reduction of at least 20 percent of GHG emissions, with additional reductions possible through the use of various lower carbon intensity natural gas and renewable natural gas options.
Natural gas vehicles have performance characteristics (power and torque) similar to diesel and gasoline vehicles.
In North America, Cummins is the leader in producing engines that operate 100 per cent on natural gas – compressed (CNG), liquefied (LNG) or renewable (RNG). At present, Cummins has over X0,000 natural gas engines in service worldwide. These include 6 to 15 litre applications in school bus, transit and truck markets. Cummins has developed these engines to meet the performance and durability requirements of the transport industry.
Natural gas and diesel blending technologies are also available for light-, medium- and heavy-duty truck applications, historically using low-pressure, spark-ignited systems.
An advanced fuel system from Vancouver-based Cespira employs compression ignition in what the company calls High Pressure Direct Injection or HPDI. The HPDI fuel system allows a natural gas engine to fully match both diesel efficiency and torque. HPDI systems have been successfully deployed in Europe since 2018. Similar European LNG trucks have been running in Alberta since the summer of 2024.
Generating a return is usually about spending less that it costs to get something from point A to Point B – resulting in profits. Finding ways to reduce emissions shouldn’t stray far from this basic principle; in other words, emissions reductions shouldn’t negatively impact the bottom line.
Determining the potential payback is often a very specific and complex calculation. Members of The Transport Project Canada (TTPC) include a number of companies and consulting firms that can help to figure this out.

There are four components that are tracked for retail fuel prices in Canada: Commodity margin; refining margin; retail margin; and taxes. Typically, commodity price fluctuations have the largest impact on the costs of petroleum fuels, though lately increased taxes are also contributing to higher prices. A similar breakdown can be applied to natural gas – compressed natural gas predominantly – retail fuel prices: delivered commodity margin; compression margin; retail margin; and taxes. The graphic illustrating prices takes average monthly cost across Canada, using data retrieved from Natural Resources Canada and Statistics Canada.
The opportunity to have fuel cost savings is substantial with the use of natural gas. This can form a strong basis for accomplishing emissions reductions with no net costs, or in many cases with significant savings over time.
Provincial ferry services such as BCFerries and Societe du traversiers du Quebec have deployed natural gas-powered vessels that use liquefied natural gas. These organizations have been at the leading edge of marine LNG usage with track records of significant success.
Bulk carriers operated by Groupes Desganes and roll-on, roll-off vessels operated by SeaSpan marine are two leading private sector marine operators that use natural gas powered vessels.
Domestic marine is also an emissions intensive transport sector. By switching to natural gas significant GHG emissions reductions have been achieved.
Two emissions initiatives are impacting the Canadian marine industry. The first is the implementation of the North American Environmental Control Area which has specific provisions under MARPOL Annex VI. These regulations limit a variety of emissions, including NOx, SOx, particulate matter, and GHG emissions. More broadly MARPOL outlines a basis for reducing GHG emissions for marine vessels, through both vessel design changes and energy improvements. Natural gas as a marine fuel offers a distinct advantage as a lower emitting fuel, in terms of NOx, SOx, particulate matter, and life-cycle GHG emissions reductions.
Natural gas is currently used in Canada’s marine sector.
Vessels operating in a number of regions around the world need to have flexibility in the kind of fuel that can be used by their vessels. As a result, dual and multi fuel technologies are frequently used. Adding natural gas to the list of useable marine fuels has resulted in significant development of both dedicated natural gas and dual fuel engines. The addition of lower carbon intensity and renewable gases will significantly add to the emissions reductions opportunities for natural gas-powered vehicle used in the marine sector.
Use of natural gas in the rail sector has reached the pilot project stage.
Current generation locomotives can be converted to use natural gas as a fuel, using diesel as a pilot or ignition source as seen with the Cespira fuel system. Similar performance characteristics, as were noticed with on-road vehicles, have been observed with both high- and low-pressure injection technologies.
In North America two original equipment manufacturers provide all new and repowered locomotive engines

Natural gas in the off-road sector has reached the pilot stage.
Given the high levels of fuel usage in large mine haul trucks, these have generated the most interest. Similar technologies and approaches used with rail locomotives have been used, including low- and high-pressure injection systems. Natural gas conversions for off road applications have been limited to a small number of applications. At the largest end of the spectrum, mine haul trucks have attracted a great deal of attention. Similarly, new emissions regulations for off-road vehicles – United States Environmental Protection Agency Tier 4 requirements – make natural gas an appealing compliance option.
