Australia is considered to be the driest populated continent in the world and faces stern drought and water shortages. Reducing carbon emissions is challenging for Australia, although the Government realizes that meeting this challenge is important and commits to reducing the level of pollution caused by greenhouse gases in Australia, and voluntarily preparing for an altered climate in the near future.
The Hon. Greg Combet (Assistant Minister for Climate Change and Energy Efficiency) stated in his speech that, “Australia is already the driest inhabited continent on earth, and is heavily exposed to the impacts of climate change and faces huge environmental and economic costs from climate change impacts including on water security, agriculture, energy supply, health, coastal communities and infrastructure” (The Hon. Greg Combet AM, 2010).
1. M.Harris: Analysis on Environmental Effects
The discount rate is used as a measure to determine future costs and benefits from climate change. However, according to M.Harris, there is uncertainty when using this method. He states that other methods that include ecological as well as economic costs and benefits should be chosen. M.Harris examined two studies, one by William Nordhaus and other by Cline. William Nordhaus said that the most favorable policy would be a minute reduction in greenhouse gas emission lower than recent estimations. Whereas, Cline focused on long-term effects and used a low discount rate of 1.5% to level present and future cost. From these studies, M.Harris concluded, “Even though costs of aggressive action appeared higher than benefits for several
