Currently the Australian Government is aiming to reduce Australia's carbon emissions to 5% below 2000 emissions levels by 2020. Reforms A B C D Emissions change (compared to 2000 10% increase No change 5% 10% reduction levels) by 2020. reduction Total cost for industries to introduce 0 0.3 1.2 1.5 reform measures (billions of dollars) a. If the Government introduced a permit system, resulting in total industry permit costs being $700 million, and capital investment total costs of $500 million, what would be the expected 2020 pollutions levels compared to 2000 levels? Type LT for Less Than, E for Equal to, or GT = Greater Than. b. Consider the mining sector is responsible for 8% of Australia's overall industry carbon emissions. The Government decides to introduce the reform option D (10% reduction). How much would it cost the mining sector (including both permit and capital investment) as a result of introducing this reform? Assume the cost is directly proportionally to all industries within the Australian economy. Answer to two decimal places in billions of dollars. $ billion. c. The Australian Government decides to meet their 2020 emissions goal by issuing permits to polluters. The permits will cost industries $900 million to buy the required number of permits. Industries need to spend an additional $300 million on improving (reforming) their operations and equipment to reduce their carbon emissions under the permit system. What is the net cost to society as a result of the Government's approach? Answer to the nearest whole number in millions of dollars (with no decimal places). $ million
