Climate Change

Scientific evidence strongly suggests that the rapid buildup of greenhouse gases in the atmosphere is raising the earth's temperature and changing the earth's climate with many potentially serious consequences.

Nitrogen Oxide Emissions

While total N2O emissions are much lower than CO2 emissions, N2O is approximately 310 times more powerful than CO2 at trapping heat in the atmosphere (IPCC 1996).

Mobile sources are the second largest producer of N2O.

Traffic Average MCI coach has

seating for 56 passengers

Assuming some existing car pooling, one coach could easily take 40 cars off the road during rush hour.

Privileged and Confidential14 of 26

Traffic Energy and Emissions

Year 2000 average Canadian car fuel economy was 24.2 miles per U.S. gallon, or .0412 gallons per mile per car which generates .3605 kg CO2 per mile per car.

40 passenger cars would release 14.42 kg CO2 per mile.

Typical MCI intercity coach fuel economy is 6.7 mpg, or .149 gallons per mile per coach which generates 1.49 kg CO2 per mile per bus.

If one coach could replace 40 cars during rush hour commutes, it would generate 11 times less CO2, and save 1.5 gallons per mile.

However, for the last 30 years, while intercity bus miles traveled in Canada has not shown any trend, the number of passengers has declined. In the U.S., this trend has not been demonstrated. Therefore, bus usage has become less optimized in Canada.

Canadian Bus Usage

If Canadian Bus Usage could be returned to the 1970 level, we could take over 20 Million car trips off the Canadian roads, and save at least 387 kg of CO2 per mile traveled.

Less traffic congestion would also further reduce the emissions generated by the remaining vehicles on the street, through smoother flowing traffic.

MCI Climate Change Initiatives/Opportunities:

Natural Gas Fueled Engines:

Compared to current Diesel Engines:

– 50% less NOx emissions

– up to 25% less CO2

– significant reductions in other toxic emissions

Privileged and Confidential19 of 26

MCI Climate Change Initiatives/Opportunities: MCI CNG fueled Commuter bus is currently offered.

Future opportunities for LNG Commuter Bus and CNG/LNG short haul Tour Coach.

Challenges:– Current CNG/LNG DDC S60 engine carries a tremendous cost penalty.

The S60G engine is currently the only CNG/LNG engine available in the power range required for our bus/coach size/weight.

– Low cost, light weight fuel tanks.

– R & D costs for MCI to develop LNG Commuter Coach ~ $2 Million (US).

Opportunities:– possible alternative CNG/LNG engine development cooperative program

with Westport Innovations of Vancouver, B.C.

MCI Climate Change Initiatives/Opportunities:

Diesel fueled Hybrid-Electric Powered:

Compared to current conventional Diesel Powertrains:

– 50% less NOx emissions*

– 50% less CO2 emissions*

– significant reductions in other toxic emissions

* over CBD-14 standard driving cycle

Privileged and Confidential21 of 26

MCI Climate Change Initiatives/Opportunities: MCI does not currently offer a Diesel Hybrid Electric

powertrain bus.

Future sales opportunities for Hybrid- Electric Commuter Buses.

Challenges:– R & D costs for MCI to develop a Hybrid Powered Commuter Coach ~ $2

Million (US)

– Cost of hybrid components are still high, therefore the hybrid bus will also carry a significant cost penalty.

Opportunities:– MCI currently has an opportunity with Allison Electric Drives to co-

develop an advanced Parallel Hybrid-Electric commuter bus.

Privileged and Confidential22 of 26

MCI Climate Change Initiatives/Opportunities:Low Emission Auxiliary Power Units (APU):

Current Commuter Buses and Coaches often spend a great deal of time idling, to maintain interior comfort levels (heat in winter, A/C in summer), and electrical accessories.

A typical Coach or Commuter Bus spends 40% of it’s time with the engine at idle. This corresponds to about 2000 gallons of fuel, and generates approximately 20,000 kg of CO2, per year per bus. With over 3000 coaches in Canada alone, this corresponds to 60 Million kg of CO2 per year. For all of North America, 880 Million kg of CO2 are generated by coaches idling.

A low emission, high efficiency APU could generate electricity to run the bus/coach “hotel loads”, and allow the main engine to shut down, thereby conserving fuel and reducing emissions.

Privileged and Confidential23 of 26

MCI Climate Change Initiatives/Opportunities:

MCI does not currently offer a low emission APU.

Future opportunities to use small Fuel Cells, MicroTurbines, or other low emission, high efficiency auxiliary power sources.

Challenges:– MCI does not currently have the budget (or necessary expertise) to

develop the APU systems.

– Cost of Fuel Cells are still high, therefore the APU may also carry a significant cost penalty.

Opportunities:– Canada is the leader in Fuel Cell technology, with several companies

developing different fuel cell systems.

Privileged and Confidential24 of 26

MCI Climate Change Initiatives/Opportunities:

Driver and Mechanic Training:

Current and future Bus and Coach drivers and service personnel can be trained to:

– minimize bus idling times (park in shaded areas in summer, etc.)– drive smoothly to conserve energy and reduce emissions– maintain the bus/coach in a “clean” and efficient state of tune

(brakes aren’t dragging, etc.).

However, MCI currently does not have the budget to expand training programs.

Summary:

Opportunities for MCI to help reduce climate change:

CNG/LNG powered buses/coaches

Hybrid-Electric powered buses

High Efficiency, Low Emission APUs to reduce idle time

Summary:

Opportunities for the Canadian and Manitoba Governments:

provide R&D assistance for the “green” technology bus projects, and training initiatives.

increase bus ridership in Canada.

offset “green” technology bus costs with Tax Incentives or Subsidies for bus/coach operators:

– ~ $50,000 (US) for each Hybrid bus– ~ $80,000 (US) for each CNG/LNG bus– ~ $30,000 (US) for each APU equipped bus– reduce fuel taxes on ultra low sulfur Diesel fuel, CNG and other

possible “clean” fuels.
