A carbon tax is a tax imposed on the carbon content of fuels. It is a form of carbon pricing. Carbon taxes are a possible cost-effective means of reducing greenhouse gas emissions. From an economic outlook‚ carbon taxes are a type of Pigovian tax.They help to address the problem of emitters of greenhouse gases not face the full social costs of their actions. Carbon taxes can be a degenerating tax‚ in that it may directly or indirectly affect low-income groups disproportionately. The regressive impact

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

Carbon nanotubes describes a specific topic within solid state physics‚ but is also of interest in other sciences like chemistry or biology‚ actually the topic has coating boundaries‚ because we are on the molecule level. The carbon nanotubes have in the recent years become more and more popular to the scientists. Initially‚ it was the spectacularly

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

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

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

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
