Carbon Footprint briefly defined is the amount of CO2 left behind after any human activity. They can be classified into primary and secondary footprints. [ (McLean 2008) ] Primarily‚ it is the direct emission of CO2 from burning fossil fuels or any kind of fuels. They are considered the main and biggest source of CO2 emission‚ thus the having biggest Carbon Footprints. [ (McLean 2008) ] The CO2 emissions from all products and their life-cycles are considered as secondary footprints. The life-cycle

fuels‚ substandard emission techniques‚ and an ever growing population all play an intricate role of raising Earth’s overall temperature. Each can be linked through one key adversary‚ carbon dioxide. Rising CO2 levels are almost the sole reason temperatures are rising at such an alarming rate. Aside from water vapor‚ carbon dioxide is a chief ingredient in our Greenhouse Effect stew. It’s everywhere. It emits from our cars‚ it flies from our smokestacks‚ and it empties from our lungs. All of Earth is

Carbon Monoxide Carbon monoxide (CO) is a colorless‚ odorless‚ and tasteless gas that is slightly less dense than air. It is toxic to humans and animals when encountered in higher concentrations. Every year‚ at least 430 people die in the U. S. from accidental CO poisoning. It is also produced in normal animal metabolism in low quantities. In the atmosphere‚ it has a role in the formation of ground-level ozone. Carbon monoxide consists of one carbon atom and one oxygen atom‚ connected by a triple

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

Carbon Footprint Over the next twenty to two hundred years‚ sixty-five to eighty percent of carbon dioxide will be observed into the ocean. This results in affecting the earth over thousands of years after (Carbon Dioxide). Along with this in twenty-twelve‚ eighty-two percent of carbon dioxide was produced from human activities (Calculator). This results in not only harming the world for the next thousand of years‚ but also affects the air we breathe in everyday. In addition‚ the United States average

Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member

A carbon footprint is "the total set of greenhouse gas (GHG) emissions caused by an organization‚ event or product" [1]. For simplicity of reporting‚ it is often expressed in terms of the amount of carbon dioxide‚ or its equivalent of other GHGs‚ emitted. The concept name of the carbon footprint originates from ecological footprint discussion.[2] The carbon footprint is a subset of the ecological footprint and of the more comprehensive Life Cycle Assessment (LCA). An individual‚ nation‚ or organization’s

Activated Carbon Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface

Carbon Dioxide from Cars U.S. states are beginning to attack another major source of global warming pollution besides power plants: your car. David Biello reports Cars in California offer a new kind of sticker shock this year: carbon. In addition to the familiar smog ratings‚ labels on new Cali cars rank them 1 to 10 based on greenhouse gas emissions. The best‚ a perfect 10‚ will emit less than 200 grams of greenhouse gases per mile. The bad ones more than 520. Vermont will also begin offering
