Carbon emission abatement can be achieved by various means, for example, regulation (controlling the emitting of carbon on the same basis as governments control other pollutants), by subsidising consumption of renewable technologies using wind or the sun, by subsidising non-carbon polluting technologies and by supporting research into innovative green technologies. Another way of achieving reduction in carbon emissions is a pricing scheme such as a cap-and-trade emissions trading scheme (ETS), which could exist in Australia by 2014, and China probably by 2015. Nations have also achieved reductions through energy conservation. Discuss (1) the various options available for carbon abatement, their merits and weaknesses, and (2) the role government and business have to play if the methods are to achieve their objectives.

Global warming is a complicated issue faced by leaders of today. Warnings are becoming increasingly amplified, in the wake of a realisation that a disastrous future ahead because of the perpetual accumulation anthropogenic greenhouse gases — emanating from fossil-fuel combustion and burning forests. PM Tony Blair told BBC news that scientific evidence of global warming was "overwhelming" and its consequences "disastrous". Global warming is the observed increase in the average temperature (f the Earth's atmosphere and oceans in recent decades (Brenneman 2009). The Earth's average near-surface atmospheric temperature increased by 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century (The Universe-Galaxy-Stars 2012).
Global warming and climate change have already unleashed untold suffering to thousands of people across the face of the earth. Think of the millions of environmental refugees who have been forced to vacate the land of their forefathers because of flooding. Thousands of children in Africa have been born into lives of poverty, disease and famine, resulting from shifting climatic conditions (Andorra 2011, quoted in Africa - Up in Smoke, 2012, 12). In Niger for example, drought and famine claimed the lives of nearly 70 people (BBC News 2012), whilst later in the year, unexpected flooding displaced 150000 families, stirred up a cholera outbreak and claimed more lives. In Australia and the US, wild raging fires have destroyed the habitat of thousands of species, reducing beautiful vast “carpets” of green thriving with flora and fauna; into barren lifeless stretches of sparsely vegetated, stunted and horrid landscapes with little biodiversity.
Alaska news reports that by August, 62.9% of the continental US was experiencing moderate to exceptional, whilst intensified convection over the Caribbean also brought heavy rains to Colombia, where flooding displaced an estimated 1.5 million people. Thousands of pages can be authored to document the incalculable grave impacts global warming has caused to our beloved mother earth. It is even more astonishing when you realise that all this anguish has been borne by people who are now alive today. You cannot help but wonder what it shall be like in the more distant future. A continued surge in Co2 levels for another century will see gases reach a level unheard of since millions of years ago. The consequences are anticipated to take many centuries to be fully manifested, as the Earth transforms into a new state. In the distant future, eras with high CO2 are anticipated where sea levels will be even higher and temperature will soar to catastrophic levels: a planet grossly unlike the one to which the human species is adapted (Conservation Foundation 1963).
By now you may be wondering “, what is the link between Global Warming and Carbon Emissions?” After all, the essence of this account is a mere review of the various means by which Carbon Emissions may be reduced. Scientific research has established a...
