explain the term of carbon footprint in 100 words
Answers
Answer:
A carbon footprint is defined as 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.
Your carbon footprint is the sum of all emissions of CO2 (carbon dioxide), which were induced by your activities in a given time frame. Usually a carbon footprint is calculated for the time period of a year.
The best way is to calculate the carbon dioxide emissions based on the fuel consumption. In the next step you can add the CO2 emission to your carbon footprint. Below is a table for the most common used fuels:
Examples of carbon dioxide (CO2) emissions:
For each (UK-) gallon of petrol fuel consumed, 10.4 kg carbon dioxide (CO2) is emitted.
For each (US-) gallon of gasoline fuel consumed, 8.7 kg carbon dioxide (CO2) is emitted.
If your car consumes 7.5 liter diesel per 100 km, then a drive of 300 km distance consumes 3 x 7.5 = 22.5 liter diesel, which adds 22.5 x 2.7 kg = 60.75 kg CO2 to your personal carbon footprint.
What is a carbon footprint - definition
A carbon footprint is the sum of all emissions of greenhouse gases (usually mainly CO2)
Examples for carbon footprint contributions:
fuel type unit
CO2 emitted per unit
Petrol 1 gallon (UK) 10.4 kg
Petrol
1 liter 2.3 kg
Gasoline 1 gallon (USA) 8.7 kg
Gasoline 1 liter 2.3 kg
Diesel 1 gallon (UK) 12.2 kg
Diesel 1 gallon (USA) 9.95 kg
Diesel
1 liter 2.7 kg
Oil (heating)
1 gallon (UK) 13.6 kg
Oil (heating) 1 gallon (USA) 11.26 kg
Oil (heating)
1 liter 3 kg
Each of the following activities add 1 kg of CO2 to your personal carbon footprint:
Travel by public transportation (train or bus) a distance of 10 to 12 km (6.5 to 7 miles)
Drive with your car a distance of 6 km or 3.75 miles (assuming 7.3 litres petrol per 100 km or 39 mpg)
Fly with a plane a distance of 2.2 km or 1.375 miles.
Operate your computer for 32 hours (60 Watt consumption assumed)
Production of 5 plastic bags (see article about carbon footprint of plastic bags)
Production of 2 plastic bottles
Production of 1/3 of an American cheeseburger (yes, the production of each cheeseburger emits 3.1 kg of CO2! It has a very large carbon footprint)
To calculate the above contributions to the carbon footprint, the current UK mix for electricity and trains was taken into account.
Carbon dioxide is a so called greenhouse gas causing global warming . Other greenhouse gases which might be emitted as a result of your activities are e.g. methane (CH4) and nitrous oxide [N2O]. These greenhouse gases are normally also taken into account for the carbon footprint. They are converted into the amount of CO2 that would cause the same effects on global warming within a certain time frame, usually 100 years (this is called equivalent CO2 amount).
Few people express their carbon footprint in kg carbon rather than kg carbon dioxide. You can always convert kg carbon dioxide in kg carbon by
