Annual greenhouse gas emissions in Australia have historically been steadily increasing. However, in recent years this trend has stopped and the rate of emissions has stabilized. The nation of Australia emitted between 250,000 and 450,000 tonnes of greenhouse gases per year from 1990 to 2010. Data from 2008 to 2012 shows that carbon dioxide emissions are a fraction of total greenhouse gases. This goes beyond the limit agreed in the Kyoto Protocol and therefore appropriate measures need to be taken. In this scenario several possible solutions present themselves: • Carbon taxes • Buy the necessary amount of carbon credits • Make the extraction process more efficient • Reduce coal mining in general • Alternative sources Carbon tax is what many they call government carbon pricing policy. The idea is that polluters will pay per ton of carbon they release into the atmosphere. This cost was initially set at $23 and will increase until 2015. In 2015 we will move to an exchange scheme that will allow the market to set the cost. This idea is widely popular and is considered the most effective and least costly mechanism for reducing carbon production and reducing the level of climate change that is occurring. The way carbon taxes can directly affect pollution is that they take into account which mines and power plants give off the worst pollution. For example, normally energy from a dirty power plant that emits a large amount of pollution will be considered equal to a clean power plant that is capable of producing the same amount of energy despite being smaller. The carbon tax will be variable so that products from dirtier sources that cause more pollution will be more expensive than cleaner ones. This is... half of the paper... Combined Asification Cycle The fluidized bed combustion method can burn various energy sources, not just coal. This method focuses on reducing sulfur oxide and nitrous oxide levels by up to 90%. The processes involved in this method involve burning coal in a reactor containing a filter that passes gas to keep it in an agitated state. The improved technology therefore uses the heat exchanger and fluidized bed combustion system to operate at lower temperatures than standard pulverized coal combustion systems. Streams of gas at increased pressures are then passed through the filter to activate a turbine, which, in turn, generates electricity. Fluidized bed combustion methods can be divided into a couple of groups depending on whether it is pressurized or not, and another two groups depending on whether the fluidized filter circulates or bubbles.
