AIR TRAVEL

Each mile of commercial air travel produces a little more than half a pound of carbon dioxide per person. Each passenger on a one-way flight from Denver to San Francisco is responsible for about 608 pounds of carbon dioxide emissions.

CAR TRAVEL

Burning a gallon of gasoline emits almost 20 pounds of carbon dioxide. A typical late-model, mid-sized sedan produces about 9,500 pounds of carbon dioxide each year, while a hybrid car generates less than half that, about 4,300 pounds.

SOLID WASTE

Every ton of waste recycled instead of landfilled keeps the equivalent of more than 6,500 pounds of carbon dioxide out of the atmosphere. By capturing the methane released from its landfill, Salt Lake City avoids the equivalent of about 32 million pounds of carbon dioxide emissions each year.

LED TRAFFIC SIGNALS

In 2001, Portland, Ore., replaced about 13,300 incandescent traffic signals with LED lamps. The new bulbs keep almost 5 million pounds of carbon dioxide out of the atmosphere each year, reducing greenhouse gas emissions by city government operations by 3 percent. The cost of purchasing and installing the new bulbs was recouped in less than three years, and the bulbs save about $400,000 in energy and maintenance costs each year.

COMPACT FLUORESCENT BULBS

Replacing six interior incandescent bulbs with compact fluorescents can keep 566 pounds of carbon dioxide out of the atmosphere — and save you about $30 — each year.
