Australia’s Annual Greenhouse Gas Emissions

829 Words2 Pages

Australia’s annual greenhouse gas emissions have historically been steadily increasing. However, in recent years this trend has stopped - the emissions rate has steadied. The Australian nation has been emitting in the range of 250,000 to 450,000 thousand metric tons greenhouse gases per year from 1990 to 2010.

Data from 2008 to 2012 show the carbon dioxide emissions as a fraction of the total greenhouse gas.

This goes beyond the limit agreed in the Kyoto Protocol, and hence appropriate measures need to be taken. Several possible solutions present itself in this scenario:
• Carbon Taxes
• Buy the necessary amount of carbon credits
• Make mining process more efficient
• Reduce coal mining overall
• Alternative sources
Carbon tax is what many people call the government’s policy of pricing carbon. The idea is that polluters will pay per tonne of carbon they release into the atmosphere. This cost was initially set at $23, and will increase until 2015. In 2015, there will be a shift to a trading scheme that will let the market set the cost. This idea is widely popular, and is thought of as the most effective and least costly mechanism to reduce carbon output and reduce the level of climate change that is occurring. The way carbon taxes can affect pollution directly is that it takes into account which mines and power stations emanate the worst pollution. For example, normally power coming from a dirty power station which emits a large amount of pollution will be considered to be equal to a clean power station which is able to produce as much energy despite being smaller. The carbon tax will be variable to this such that products from dirtier sources that cause more pollution will be more expensive than the cleaner ones. This is...

...asification Combined Cycle
The Fluidized Bed Combustion method can burn several sources of energy – not just coal. This method focuses on reducing sulphur oxide and nitrous oxide levels by up to 90%. The processes involved in this method are burning coal in a reactor containing a filter which lets gas passed through it to keep it in an agitated state. The better technology then uses the heat exchanger and the fluidized bed combustion system to work at cooler temperatures as opposed the standard pulverized coal combustion systems. Gas streams with increased pressures through the filter are then made to activate a turbine, which, in turn, generates electricity.
Fluidized Bed Combustion methods can be split into a couple of groups depending on whether it is pressurized or not, and a futher two groups depending on whether the fluidized filter circulates or bubbles.
