Australia's annual greenhouse gas emissions have historically increased steadily. However, in recent years this trend has stopped and the emission rate has stabilized. The nation of Australia emitted between 250,000 and 450,000 thousand tonnes of greenhouse gases per year between 1990 and 2010. Data from 2008 to 2012 shows carbon dioxide emissions as a fraction of total greenhouse gases. tight. This goes beyond the agreed limit. in the Kyoto Protocol and appropriate measures must therefore be taken. There are several possible solutions in this scenario: • Carbon taxes • Buy the necessary amount of carbon credits • Make the extraction process more efficient • Reduce coal mining in general • Alternative sources The carbon tax is what many call the government carbon pricing policy. The idea is that polluters will pay per ton of carbon they put into the atmosphere. This cost was initially set at $23 and will increase until 2015. In 2015, we will move to a trading system that will let the market set the cost. This idea is very popular and is considered the most effective and cost-effective mechanism for reducing carbon production and mitigating the level of ongoing climate change. The way carbon taxes can directly affect pollution is that they take into account the mines and power plants that generate the worst pollution. For example, energy normally coming 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 as much energy although it is smaller. The carbon tax will be variable, so products from dirtier and more polluting sources will be more expensive than cleaner products. This is...... middle of paper...... Combined cycle of asificationThe fluidized bed combustion method can burn multiple energy sources - not just coal. This method aims to reduce 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 the gas to keep it in an agitated state. The best technology then uses the heat exchanger and fluidized bed combustion system to operate at cooler temperatures, unlike standard pulverized coal combustion systems. Gas flows with increased pressures through the filter are then caused to activate a turbine which, in turn, generates electricity. Fluidized bed combustion methods can be divided into two groups depending on whether they are pressurized or not, and two other groups. depending on whether the fluidized filter circulates or bubbles.
