  • Carbon FootPrint is historically defined as “ the total sets of green house gas emissions caused by an organization , event , product or person. • The total carbon foot print cannot be calculated because of the large amount of data required and the fact that carbon di oxide can be produced by natural occurences.
• 3.
  • It isfor this reason that Wright , Kemp , and Williams , writing in the journal Carbon Management , have suggested a more practicable definition : • A measure of the total amount of Carbon di oxide ( Co2) and methane ( CH4) emissions of a defined population system or activity considering all relevant sources sinks and storage. • Green House Gases ( GHG) can be emitted through transport , land clearance , and the production of consumption food .

  • For simplicityof reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted. • Most of the carbon footprint emissions for the average U.S. household come from "indirect" sources, i.e. fuel burned to produce goods far away from the final consumer. These are distinguished from emissions which come from burning fuel directly in one's car or stove, commonly referred to as "direct" sources of the consumer's carbon footprint.[4]

  • The conceptname of the carbon footprint originates from ecological footprint, discussion,[5] which was developed by Rees and Wackernagel in the 1990s which estimates the number of "earths" that would theoretically be required if everyone on the planet consumed resources at the same level as the person calculating their ecological footprint.

  • Carbon emissions,most notably carbon dioxide (CO2), are part of a collection of gases that negatively influence the quality of our air and increase the greenhouse effect. Greenhouse gases have a direct influence on the environment, causing extreme weather changes, a global temperature increase, the loss of ecosystems and potentially hazardous health effects for people.

  • The U.S.Energy Information Administration states that greenhouse gases are gases that keep heat in the earth’s atmosphere. They do this by making it easier for sunlight to enter the atmosphere. And when the sun’s rays hit the earth, they also cause a reflection — infrared radiation — which is what stays in the earth’s atmosphere due to greenhouse gases. Although greenhouse gases do occur naturally, human activity contributes a great deal to greenhouse gas emissions. Your carbon footprint — or your impact .

  • A greenhousegas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would average about 33 °C colder, which is about 59 °F below the present average of 14 °C (57 °F)

  Appliance Use •Probably rely on a variety of appliances each day to complete different tasks. But according to Carbon Footprint, using electricity, coal, gas and oil helps create a large carbon footprint. Time For Change indicates that for every 32 hours you have your computer on, 1 kg of carbon dioxide is emitted into the environment. Carbon Footprint identifies several different household appliances as being the main contributors to a large carbon footprint: Electric dryers, refrigerators, freezers, ovens and dishwashers emit carbon dioxide each time they are used.

  Water Use •Carbon Footprint reports that consumers are wasting "huge quantities" of potable water by using it for non-essential purposes. Cleaning water also takes a great deal of energy to make it safe for human consumption. Carbon Footprint recommends collecting rainwater to use for purposes other than drinking. Paying close attention to how you use your water and how much you use can help reduce the size of your carbon footprint.

  Driving and Travelling • Driving a car is convenient and often necessary for travelling long distances. Time For Change, a website that focuses on improving the environment, reports that for each gallon of gas used, 8.7 kg of carbon dioxide is emitted. The more you drive, the more harmful carbon dioxide your car emits into the air.

  Facts on carbonfootprint • There has been a huge amount written about Global Warming and how it is effecting our lives now and what might happen in the future. Some of the Superpowers are using their political muscle to promote the reduction of Greenhouse Gases and others to oppose it for whatever reasons. The fact is that the actions of the human race are damaging the earth in many ways.

  Carbon footprint calculator • The seven sources of CO² from fossil fuel combustion are (with percentage contributions for 2000-2004: • Solid fuels (e.g. coal): 35% Liquid fuels (e.g. petrol): 36% Gaseous fuels (e.g. natural gas): 20% Flaring gas industrially and at wells: <1% Cement production: 3% Non-fuel hydrocarbons: <1% The "international bunkers" of shipping and air transport not included in national inventories: 4%.

  Carbon offsets •Carbon Offsetting is the term given to the act of doing something 'green' to compensate for some or all of your Carbon emissions. This can be done by planting trees yourself to reduce the carbon dioxide in the atmosphere, by planting trees as a Biofuel for harvesting in ten years time, or by generating your own renewable energy to go back to save on the use of Fossil Fuels for electricity generation.
