In 2010‚ Labor Prime Minister Julia Gillard decided to implement carbon tax in order to gain more support in response to the change in climate (http://isen.northwestern.edu/doc/pdf/URG-ISEN_ALloyd.Jun12_ProjectSummary.pdf) and on the 8th of November 2011‚ the ‘Clean Energy Legislative Package’ is then passed by the Senate which sets out the way that Australia will introduce the carbon tax to reduce carbon pollution (http://www.deloitte.com/view/en_AU/au/services/assurance/accountingtechnical/wha

Carbon tax is an environmental tax levied on the carbon content of fuels. It is a form of carbon pricing. Carbon is present in every hydrocarbon fuel ‚ such as coal‚ petroleum‚ and natural gas. It is then released as carbon dioxide (CO2) when they are burnt. In contrast‚ non-combustion energy sources—wind‚sunlight‚ hydropower‚ and nuclear—do not convert hydrocarbons to CO2. CO2 is a heat-trapping "greenhouse" gas. Scientists have debated and discussed the potential effects on the climate system of

ABSTRACT We are in debt to Carbon Dioxide (CO2) and other green house gases for our presence on earth. As they help in stabilizing temperatures to levels sustainable for organic life – by what is known as green house effect. In modern times burning of fossil fuels like coal‚ oil‚ and natural gas combined with fast deforestation has led to unprecedented level of green house gas emission. Here came in to existence the concept of Carbon Emission Trading developed during the Kyoto Protocol in 1997

Carbon Footprint The term “carbon footprint” refers to the amount of carbon dioxide we emit into the air every year. C02 is produced by many sources and is the gas responsible for Global warming and alarming changes in our climate. As we use our resources‚ the negative impact on our environment increases. The more C02 emitted in the air the more our ozone layer is affected. C02 is a natural gas and is always being emitted and absorbed to and from the air. There is a certain amount of carbon

It is also a basis of all life and continually cycled and globally existed. Carbon dioxide is obtained from various sources‚ including emissions from volcanoes or industries and combustion products of organic compounds and the respiratory activity of living organisms. Carbon dioxide not only going into the atmosphere through the

ASSIGNMENT: 1 SESSION: 2012/13 TUTOR: Stuart Allan WORD COUNT: 1‚891 Carbon fibre is a strong‚ yet light‚ reinforced polymer. Carbon fibres are used in applications where high strength and light weight are required. Carbon fibres can also be easily moulded into the desired shape. They are also chemically inert‚ resistant to heat‚ and do not expand under changing temperatures. Machining of carbon fibre materials can generate airborne particles. The potential health effects of

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

ecological accounting‚ introduces some of the most important Footprint findings‚ and addresses provocative questions: Do we fit on the planet? How can the Footprint foster sustainable human development? How do carbon emissions contribute to humanity’s Ecological Footprint? Footprint Basics - Overview Humanity needs what nature provides‚ but how do we know how much we’re using and how much we have to use? The Ecological Footprint has emerged as the world’s premier measure of humanity’s demand on nature

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
