THE CARBON CYCLE According to the United States Environmental Protection Agency (“EPA”)‚ the increase in anthropogenic CO2 emissions has led to the increase in global temperatures in the past century . Because of the preponderance of evidence linking greenhouse gases and climate change‚ governments worldwide are developing policy to reduce CO2 emissions. CO2 can enter the atmosphere by burning fossil fuels‚ in manufacturing processes‚ and other energy-reliant activities. However‚ not all emitted

The carbon cycle shows how carbon is recycled -Carbon dioxide is taken in by plants in order to carry out photosynthesis and make food. -The carbon from the carbon dioxide is used to make carbohydrates‚ fats and proteins that make up the plant body. For example the cell wall of plants is made from cellulose - a carbohydrate. -Some of this carbon is returned into the atmosphere as carbon dioxide when the plant respires. When these plants are eaten by other animals this carbon becomes part

The Carbon Cycle Poppy Matless Carbon is present in all living organisms. When organisms die‚ the carbon is recycled for future generations. 1. Carbon is released as CO2 via respiration and combustion 2. CO2 is absorbed by producers (grass‚ plants etc) 3. Animals feed off of the plant‚ passing on carbon throughout the food chain‚ losing some carbon as CO2 respiration. 4. When the animal dies‚ it is eaten by decomposers‚ and the carbon returns to the atmosphere 5. If decomposition

Carbon is the fourth most abundant element found on Earth‚ and is essential to all life as we know it. It is found in all living substances‚ and is essentially the key element for life. Because the carbon atom has the ability to form bonds with up to four other atoms‚ it can help form solid minerals (such “ limestone)‚ ‘squishy’ organisms (such as plants and animals)‚ and it can be dissolved in water. Carbon is also present in rocks‚ dissolved in rivers‚ lakes and oceans‚ and is in the atmosphere

somewhere on time. Car emissions produce three types of carbon - Carbon Monoxide (CO) and Carbon Dioxide (CO2) and hydrocarbon (CH4) - which are traumatizing both our health and the environment. By itself‚ carbon isn’t a harmful element‚ but one of its characteristics is easily pairing up with majority the elements in the periodic table. Its ability to bond is infinite; it can create many different substances without any problems. Carbon Monoxide is a poisonous gas‚ that leads to severe poisonings

The term carbon footprint‚ therefore‚ is a shorthand to describe the best estimate that we can get of the full climate change impact of something. That something could be anything – an activity‚ an item‚ a lifestyle‚ a company‚ a country or even the whole world. CO2e? What’s that? Man-made climate change‚ or global warming‚ is caused by the release of certain types of gas into the atmosphere. The dominant man-made greenhouse gas is carbon dioxide (CO2)‚ which is emitted whenever we burn fossil

INTRODUCTION Since carbon dioxide concentration in the atmosphere is accumulating rapidly because of burning fossil fuel‚ coal‚ oil and natural gas for power generation‚ transportation‚ industrial and domestic uses‚ our earth has been facing global warming‚ sea level rising‚ flooding and other adverse changes which damage to our ecosystem. To address this challenge‚ we need to find out other alternative ways that do not produce carbon dioxide or that reduce the release of enormous amount of carbon dioxide gases

EXECUTIVE SUMMARY Carbon Credits are gaining momentum not only around the world but also in India. The Concept of Carbon Credits evolved as a step to mitigate the rising Global Warming on earth. The emission of greenhouse gases by industries and anthropogenic activities has caused irreparable damage to the atmosphere leading to rising global temperature‚ affecting human life and causing Global Warming. The Concept of Carbon Credits was therefore evolved by way of an agreement by different countries
