Efficiency - Transport

Improving environmental efficiencies in fuel standards and design

Given initiatives already underway by TC, and the Canada-U.S. Regulatory Cooperation Council, an efficiency stage strategy uses existing and emerging regulations and programmes to progressively ratchet up fuel efficiency and emission reduction requirements for all transport modes (including passenger cars) in the spirit of continuous improvement.  As discussed above, the needs are especially high for rail and air, which lag behind requirements for truck and ship.  Although industry will usually balk, from a regulatory perspective, such changes are usually straightforward since they involve changes to technical specifications that can usually be adopted through Orders-in-Council.

Encourage electric light freight vehicles

Although federal emission rules are changing to improve heavy and light trucks, a further strategy is to encourage electric light freight vehicles. For under 3.5 tonnes, conventional trucks have high emissions / tonne-km (Edwards-Jones et al., 2008), so presumably all electric or hybrid light trucks can bring down emissions more quickly than just changing standards for combustion engines and their vehicles. For trucks over 3.5 tonnes, electric power is not that viable an option.

LCA reveals that, due to battery components and assembly, production impacts on the environment are more significant for electric light vehicles than combustion ones, but use impacts are significantly lower, depending on the electricity mix.  Sensitivity analysis suggests that the cleaner the electricity mix, the lower the overall GHG emissions (Hawkins et al., 2012).

Regarding the fit with urban environments, “electric vehicles are suitable for duty cycles in (sub-)urban areas involving a low daily driving range and a relatively low load capacity. Also they work best when driving at low speed on flat terrain. Charging stations should be available at regular intervals and charging times of more than 30 minutes are required to utilise electric vehicles to their full potential .... Electric freight vehicles are best suited for last mile deliveries in compact cities involving short distance” (ENCLOSE, 2014). Range can be an issue (150-200 km a day is feasible), and there can be issues with draw on the battery from heating and cooling in extreme weather.  There are payload losses because of battery weight and elevated floors to accommodate the battery’s space requirements (ENCLOSE, 2014). Although the 20 ft container is the dominant size and would not fit on such trucks, there are currently also 6, 8 and 10 ft containers that are more suitable.

There are several strategies provinces and municipalities can employ to encourage electric truck / van fleets. Roads are primarily owned and maintained by different levels of government.  They have the authority to regulate what goes on the road.  Provinces uses vehicle registration infrastructure to regulate the types of vehicles permitted. For example, the Ontario Highway Traffic Act allows regulations for the type of equipment and vehicle registration[1].

Municipalities are permitted to regulate the types of vehicles and the amount of noise, fumes and smoke they generate. Electric vehicles produce minimal noise, and no combustion fumes. Toronto has an idling by-law.  If you’re vehicle doesn’t idle, that provides a delivery advantage. Some municipal jurisdictions have developed and implemented delivery service plans for cities to reduce pollution and noise[2].  These have numerous dimensions.  Some European cities have established low – emission zones, accessed only by low emission vehicles (ENCLOSE, 2014). Off-hour delivery is feasible in residential areas if a vehicle is green, quiet and the route is optimized to assure efficient delivery.  Under those conditions, qualifying vehicles can delivery anytime, otherwise time restrictions are imposed, particularly night time restrictions. Special parking zones exist for delivery e-trucks with charging stations in some German cities. Allowing electric freight vehicles free passage on toll roads is another proposal (ENCLOSE, 2014).  Toronto’s municipal code (chapter 591) already exempts electric cars from the definition of a motor vehicle so this could be extended to electric freight trucks.  This would facilitate exemption from rules on unloading in specified zones at restricted times[3]. Toronto also has rules on loading standards for new developments, and these are more onerous in the downtown area (MMM Group, 2009), but could be relaxed if the locations were serviced by electric freight vehicles.  Since charging stations is important infrastructure for electric vehicles, installing charging stations on those sites would also enhance the viability of the approach.   Tax credits are provided in some parts of the US to commercial applicants installing such stations (ENCLOSE, 2014).  If public and parapublic agencies were to institute progressive fleet replacement programmes involving electric vehicles and charging infrastructure, the utility of e-trucks would be accelerated.

Measures to reduce trucking – cabotage, fees, tolls and taxes

Given the mode preference hierarchy presented above, the long term strategy involves shifting food delivery out of trucks.  Ultimately, it means that truck freight and the trucking industry has to shrink. In the near term, the focus is to ensure truck freight is optimized (ie. limit empty or semi loads) and that routes minimize food miles.  One area that needs changing is the cabotage[4] rules.  Cabotage rules evolved in earlier periods when domestic economic development and national security were priorities, eras in which understanding of ecology was significantly limited and environmental problems not apparent.

Designed to protect domestic sectors, these rules have the effect of generating ecological inefficiencies and, based on differential application of said rules across modes, favouring certain modes over others.  While NAFTA provisions on cabotage have not really been relaxed in shipping with the US, they have in trucking (related to international point to point routes and drivers) which has helped increase truck freight.  Some changes under NAFTA between Mexico and Canada did increase shipping at the expense of trucking, again suggesting that differentiated rules can favour one over the other (Higgins and Ferguson, 2011).  Unfortunately, no North American intermodal concept has been implemented though it has been discussed during NAFTA negotiations (Blank and Prentice, 2012).

Regulated under the Customs Act and Customs Tariff (cargo, vehicles, container) and the Immigration and Refugee Protection Act (drivers), cabotage in trucking needs to be modified to make truck freight more efficient.  The current rules restrict certain kinds of backhaul and topping up of loads with domestic goods, and altering the route to accommodate such measures, all of which which means semi-empty or empty trucks (Kiselbach, 2013). These rules need to be changed.  Total deregulation of cabotage is not recommended because that could create more truck traffic and over longer distances.

Changing US cabotage rules in shipping will be challenging.  The Jones Act in the US is a fundamental obstacle to enhancing short sea shipping along the coastal waterways (Blank and Prentice, 2012). Some analysts suggest the Act will be difficult to change and it’s better to create a North American flag for US and Canadian ships that permits equal treatment in each other’s waters.  Some adjustments to the Canada Coasting Trade Act would be required to facilitate this, in particular providing licences and waiving fees and duties for US ships engaging in coastal shipping of freight under such flags. It is thought that such shifts would take freight out of coastal trucking.  In Canada, Montreal is a major port and a current challenge is that seaway ships are smaller than ocean ships, so containers have to be moved in Montreal, but why not ship more at least to Toronto or Hamilton? MacRae et al. (2013) provide one case study of the GHG reductions associated with maximizing ship movement.

Cabotage in air should be maintained since the proposals below are designed to discourage air freight.

There are also many fees and tolls for cost recovery (Higgins and Ferguson, 2011).  To comply with the mode preference hierarchy, policies that encourage trucking need to be modified or fees and tolls for trucking should be elevated while those for rail and ship should be reduced. For example, the US Harbour Maintenance Fee appears to encourage trucking over short sea shipping between Canada and US, especially for higher value items. Efforts to create exemptions for short sea shipping have so far failed in the US.  Charges for customs and coast guard could also be reduced to encourage short sea shipping that moves cargo out of trucks. Toll reductions on locks are already in place for new business, so this measure could be extended to other charges (Higgins and Ferguson, 2011).

Tie freight into transit

In the spirit of exploring underutilized infrastructure, some jurisdictions have proposed using existing transit lines to move freight.  “Implementation ideas include the night-time use of rail or bus rapid transit lines for freight, the addition of freight cars to subways or commuter rail trains, or the use of rapid transit rail lines by freight-specific vehicles at regular, scheduled times during the day” (Metrolinx, 2011). Night-time use is likely dependent on using electric vehicles to mitigate noise and idling, suggesting the use of electrified street car lines where they exist, or the transition to more electric light trucks as discussed above.  Such schemes require full feasibility studies.

Tax aviation fuel

In many countries aviation fuel is untaxed, typically on international flights and many jurisdictions no longer tax fuel on domestic flights.  In Canada, taxes are levied provincially, with Ontario planning to raise taxes, but other provinces reducing or eliminating them. “British Columbia became the latest province to eliminate its international fuel tax in 2012, joining New Brunswick, Alberta, Quebec and Saskatchewan. Newfoundland and Labrador has no fuel tax for international flights but charges tax for flights to the United States. Manitoba has the highest rate at 3.2 cents, but nothing for U.S. and international cargo flights ….. While some provinces have eliminated fuel taxes on international flights, they all charge for domestic flights, ranging from 0.7 to 3.2 cents per litre. At 6.7 cents, Ontario would be more than double its provincial neighbours. Most U.S. airports charge little or no fuel taxes.” (Canada Press, 2014).  The federal government charges rents at airports, navigation fees and security charges which are likely more targeted to passenger traffic but have some impacts on cargo as well, since cargo is moved on passenger flights.

Given these recent shifts, and the complications of taxing international flights and obtaining an international agreement on a tax regime, re-establishing taxes on passenger traffic is unlikely in the near term.  However, maintaining or re-establishing fuel taxes on dedicated cargo planes might be feasible, with a medium term objective to also tax, on a proportional basis, fuel on passenger flights carrying cargo.

Improve transport of animals

The federal government regulates animal transport under the Health of Animals Regulations, Part XII, though many elements are quite general or considered by some welfare specialists to be too lax. As a result, some organizations have developed voluntary codes that build upon the existing regulations, including animal welfare groups, the organic sector, the National Farm Animal Care Council (NFACC) and Local Food Plus.  These voluntary codes exhibit different degrees of precision and welfare improving requirements, but as a collectivity reflect the weaknesses of existing regulations.  At a minimum, the Health of Animals Regulations should be improved to an NFACC standard, in other words creating a new mandatory minimum.  The other standards can still be pursued on a voluntary basis.
