Carbon Footprint

Carbon footprint is the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. (CO2 is the chemical symbol for carbon dioxide). When you heat your house with oil, gas or coal, then you also generate CO2. Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods also emitted some quantities of CO2.
I measured my carbon foot print at some sites in the internet and many people can calculate their carbon footprint from these sites, for example:

  http://footprint.wwf.org.uk/
  
  http://www.myfootprint.org/
  
  In these three sites I calculate my average of the equivalent number is 17.93 tonnes per annum. Then I compare my number to the others student that calculated their carbon footprint. First Abdulla Alqasemi got 21.32 tonnes per annum, Ahmed Naji got 37.81 tonnes per annum and last Abdulla Al Aamadi got almost 30 tonnes. So I got the lowest carbon footprint in the class.
  
  Individuals can reduce their own carbon footprint by minimizing energy use in the home, traveling by public transport, using the car less, flying less frequently, buying energy efficient products, consuming goods that have used little energy in their production and transport, and minimizing waste by reducing, re-using and recycling."
