Green Cabs in Wellington
The Prius is widely considered to be most environmentally friendly vehicle available in the market today.The Prius is a series-parallel configuration hybrid, a vehicle that can run on just the engine, just the batteries, or a combination of both. Toyota's design goals are to reduce the amount of pollution and to maximize fuel efficiency. To do this, it uses a gasoline/electric hybrid powertrain, incorporating large batteries that are charged by the gas (petrol) engine directly or by regenerative braking. Either the engine or the battery (or both) can power the vehicle, depending on conditions. This gives it the acceleration and power of a standard car having a much larger gasoline-burning engine.
---> 50 million trees remove approximately one million tons of CO2 from the atmosphere each year.
The Prius emits 106gms of C02 per kmWe estimate that each car will travel an average of 60000km per annum but just to be safe we'll work off 80,000km per annum per vehicleMultiply that by the 60 vehicles we haveOur vehicles will produce about 508.8 tonnes of C02 over the course of the year. To offset our emission for this year we will need to plant 30,000 trees.
note:
the average cab driver spends approximately $80 a day on petrol, the average Green Cabbie spends approximately $20 a day on petrol.

Car versus Bus carbon emissions
by Derek Zumsteg
I came across something online that claimed that diesel buses emit 200x the pollution of a normal passenger car. I looked into this, read some studies, and it’s not true.
The average vehicle on the road emits ~1# of CO2/mile (it’s higher for light trucks, lower for cars, but it works out quite well). I looked up some testing data, and a late-90s diesel bus on low-sulfur fuel (no trap, none of the new cool technology) puts out ~6.4# CO2/mile.
So an older diesel bus = about six cars, CO2-wise.

Planes vs Trains vs Automobiles - What is Greener
here is a research from "green price blog" on the comparison of a plain vs. train vs. bus vs. automobile ride, their costs, travel time and carbon emission.
-------------------------------> <--------------------------------------------
On a trip from my home of Washington, DC to Boston, MA and back, the financial, environmental and time costs associated with each mode of transportation are:
Automobile:
I based this calculation on the average gas mileage of an American automobile, which is 21 MPG . According to Google Maps, the distance between Boston and DC is 441 miles (so 882 total miles). The average cost of a gallon of gasoline is $3.13, according to Energy Information Administration.--- For a round-trip drive to Boston from DC and back, the carbon emissions are 0.368 Tons of CO2. For gas alone, the trip would cost about $131.46 and would take about 8 hours each way.
Train:
I looked at the price of an Amtrak ticket, leaving on a Friday (March 7th at noon) and coming back on a Sunday (March 9th at 3:00 PM).--- For a round-trip train ride to Boston from DC and back, the carbon emissions are 0.085 Tons of CO2. The train ticket would cost about $200 and would take about 8 hours each way.
Plane:
Using Hotwire.com and the dates of March 7-9 (Fri-Sun), from BWI Airport to Logan Airport.---- For a round-trip airplane ride to Boston from DC and back, the carbon emissions are .242 Tons of CO2. The plane ticket would cost about $220 and would take about 3 hours each way.
Bus:
Using Greyhound.com and the dates of March 7-9 (Fri-Sun)--- For a round-trip bus ride to Boston from DC and back, the carbon emissions are .126 Tons of CO2. The bust ticket would cost about $100 and would take about 9 hours each way.
So the rankings for carbon emissions, cost and time (from best to worst) are as follows:
Emissions: Train, , Bus, Plane, Automobile
Cost: Bus, Car, Train, Plane
Time: Plane, Train, Car, Bus

Project1 - project debriefing
Being carbon neutral, or carbon neutrality, refers to neutral (meaning zero) total carbon release, brought about by balancing the amount of carbon released with the amount sequestered or offset. However, various special interests have attempted to promote a use of the term that refers to carbon reduction, which is clearly not neutral.
In this project, focusing on this globle issue, special attention is given to the transportation and the Wellington region.
Wellington is a very compact city where people live close to each other. Within a small and confined area, there are a lot of vehicles traveling in and out of the city everyday, emitting large amount of carbon and therefore the pollution rate can be very high.
The quickest and the most efficient way to reduce carbon emission is to reduce the amount of cars in Wellington region. With a significant amount of public transportations we have in Wellington, car is not a necessary tool for transport. As such, the target audience for this interacting game project will be mainly focusing on “drivers”, who are mostly office workers or university students. How can we create a game that can interest them, provides them an aesthetic experience, and at the same time addressed them the message that we want to convey?
