Learning About Carbon Footprints

When the topic of conversation inevitably turns toward the state of the environment, the term "carbon footprint" is frequently uttered. While many people nod their heads in comprehension, many do not have a clue what "carbon footprint" actually means.

When the words "carbon footprint" are used, they indicate a measurement of the amount of carbon dioxide or CO2 emitted through the combustion of fossil fuels. The carbon footprint applies in the case of an organization, business or enterprise -- as part of their everyday operations or, in the case of an individual or household, as part of their daily lives. Basically it is the impact people have on the environment based on the levels of greenhouse gases produced, measured in units of carbon dioxide.

According to CarbonFootprint.com, a carbon footprint is made up of the sum of two parts, the direct/primary footprint and the indirect/secondary footprint. 1. The primary footprint is a measure of our direct emission of CO2 from the burning of fossil fuels, including domestic energy consumption and transportation (e.g. cars and planes).

2. The secondary footprint is a measure of the indirect CO2 emissions from the whole life cycle of products we use -- those associated with their manufacture and eventual breakdown.

A typical person's carbon footprint features a similar breakdown. Home heating and cooling needs, electricity usage and travel needs make up the largest shares of the carbon footprint pie. Recreation and leisure, as well as use of public services make up other high areas of impact.

Reduction of the Footprint

The goal of being informed about a carbon footprint is to reduce it. Reducing a primary footprint involves finding more environmentally friendly methods of running the household, including energy-efficient heating/cooling systems, conserving electricity and water usage, etc. Reducing a secondary footprint requires a little more thought, especially when it applies to consumer purchases. Think about how items are manufactured and from where they are imported. Avoid goods shipped from far distances or those packaged in a lot of excess wrapping. These things contribute more to a carbon footprint. In the majority of areas in the United States, Canada and Europe the water is safe to drink. So simply eliminating bottled water from your lifestyle can help reduce a carbon footprint as well.

Carbon Offsetting

In addition to reducing your carbon footprint, there are ways to offset the levels of CO2 in the environment. One of the easiest things for a typical family to do so is surround themselves with more "green," and not the kind stored in a wallet. Trees, shrubs and other plants absorb CO2 for life and expel oxygen. The more trees and plants planted, the better the environment will be. It is estimated that one broad leaf tree will absorb approximately 730kg (1650 pounds) of carbon dioxide during the course of its life (approximately 100 years).

Not only does planting greenery improve the air and environment, it also provides wildlife habitats and makes for a better quality of living.
