GEOG106 ASSIGNMENT 2: CARBON FOOTPRINTS ELLA ROCHE (28682991)\ What is your personal carbon footprint‚ and what are the implications of your carbon generating behaviours for meeting future carbon emissions target? How might changes be brought about in individual and societal carbon behaviours and what changes might there be in New Zealand by 2020 and 2050 as a result? This report outlines the principles behind carbon footprints and their reduction on both a societal‚ national and global

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

Fiber optic wire carries much more information than conventional copper wire‚ and is far less subject to electromagnetic interference. A single glass fiber can carry the equivalent of 100 channels of television or 100

In order to survive‚ humans and animals must give off carbon dioxide to take in oxygen‚ whereas plants must take in the compound and give off oxygen. Carbon Dioxide has numerous unique characteristics‚ properties‚ and safety measures that everyone should be aware of. Being aware of this compound and what it
