Carbon Footprint of Mass Transportation vs an Automobile

Abstract

Different modes of transportation emit various amounts of CO2 into the atmosphere. In today's world, where global warming is an issue, the way people choose to travel makes a difference. This paper contains the calculation of the Bay Area Rapid Transit (BART) system's carbon footprint and compares it to the carbon footprint of cars traveling the same distance. The results of this calculation will hopefully cause the average commuter to reconsider his or her form of transportation.

Introduction

About BART

Every day of the week, thousands of people living in the Bay Area take advantage of the BART system. This system comprises of 104 miles of track and 43 stations, including underground tunnels and passageways (1). Also, the trains run at a swift 80 miles per hour on electric currents, bringing about fast and efficient commuting (1). The amount of passengers riding BART continues to increase. However, others decide to use alternative transports, such as driving.

The Investigation

It is important to be aware of the effects different modes of transportation have on our environment. As global warming becomes a problem facing the current world, the monitoring of greenhouse gasses emitted into the atmosphere is necessary. One way in doing such an analysis is through calculating a carbon footprint. A carbon footprint is a calculation of the total amount of CO2 derived from a source. This amount depends on the type of energy the source used (i.e. coal, gas, nuclear, etc.), how much of that energy source is used, and how long the source runs. These carbon footprint calculations are used by industries and people to plan and decrease their effect on global warming.

In addition, BART is continually seeking to reduce greenhouse gases and be a part of the climate change solution (1). Efforts to expand the system and use alternative sources of energy have been prioritized.

Commuters who use public transportation have a smaller carbon footprint than commuters who drive separate cars. Although BART needs a large amount of energy to operate, it is overall an environmentally healthier transportation than vehicles. In fact, a worker who uses BART saves more 400,000 metric tons of CO2 than a worker who drives to work (1). To a great extent, BART is a greener system than a car.
