Alcoa World Alumina and Chemicals is a joint venture between Alumina Limited and Alcoa and is abbreviated to AWAC. AWAC's business is the mining of bauxite, the extraction of alumina and the smelting of aluminium. It has about 25% of the global alumina market. Alcoa acts as the day-to-day manager.
Aluminium recycling is the process in which secondary aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. It involves re-melting the metal, which is cheaper and more energy-efficient than the production of aluminum from raw bauxite via electrolysis of aluminum oxide (Al2O3) during the Hall–Héroult and Bayer processes.
Greenhouse gas inventories are emission inventories of greenhouse gas emissions that are developed for a variety of reasons. Scientists use inventories of natural and anthropogenic (human-caused) emissions as tools when developing atmospheric models. Policy makers use inventories to develop strategies and policies for emissions reductions and to track the progress of those policies.
The Western Australian economy is a state economy dominated by its resources and services sector and largely driven by the export of iron-ore, gold, liquefied natural gas and agricultural commodities such as wheat. Covering an area of 2.5 million km2, the state is Australia's largest, accounting for almost one-third of the continent. Western Australia is the nation's fourth most populous state, with 2.6 million inhabitants.
Aluminium in Africa originates from bauxite, and within Africa is primarily found in Guinea, Mozambique and Ghana. Guinea is by far the biggest producer in Africa, and is a world leader in bauxite production.
United Company RUSAL, international public joint-stock company is the world's second largest aluminium company by primary production output. It was the largest until overtaken by China Hongqiao Group in 2015. UC RUSAL accounts for almost 9% of the world's primary aluminium output and 9% of the world's alumina production.
Prime Ministerial Task Group on Emissions Trading was a Task Group set up on 10 December 2006 by Australian Prime Minister John Howard to develop an Australian Carbon Trading Scheme. The terms of reference of the task group was:
The energy policy of Australia is subject to the regulatory and fiscal influence of all three levels of government in Australia, although only the State and Federal levels determine policy for primary industries such as coal. Federal policies for energy in Australia continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production. Australia is the 10th most coal-dependent country in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage and the coal industry produces over 30% of Australia's total greenhouse gas emissions. In 2018 Australia was the 8th highest emitter of greenhouse gases per capita in the world.
China is both the world's largest energy consumer and the largest industrial country, and ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese Government since the founding of the People's Republic of China in 1949. Since the country's industrialization in the 1960s, China is currently the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%. On a per-capita basis, China was only the world's 51st largest emitter of greenhouse gases in 2016. China is also the world's largest renewable energy producer, and the largest producer of hydroelectricity, solar power and wind power in the world. The energy policy of China is connected to its industrial policy, where the goals of China's industrial production dictate its energy demand managements.
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.
The Kurri Kurri aluminium smelter was located in Kurri Kurri, Australia and operated from 1969 until 2012. Developed by Alcan Australia Limited, the smelter experienced a change of ownership three times during its operations. Through gradual expansion, the smelter increased its production capacity from 30,000 tonnes per year (t/y) to 180,000 t/y of aluminium metal by the 1990s. The Kurri Kurri Smelter was engaged in operations in four areas; potlines for the melting of alumina, a cast house for casting of molten metal, a carbon plant for baking anodes, and anode plants for the manufacturing of carbon anodes.
The Australian Uranium Association was an Australian industry trade group which represented companies involved in uranium exploration, mining and export. It operated from September 2006 until 2013, after which its responsibilities were absorbed by the Minerals Council of Australia.
The climate policy of China is to peak its greenhouse gas emissions before 2030 and to be carbon neutral before 2060. Due to the large buildout of solar power in China and burning of coal in China the energy policy of China is closely related to its climate policy. There is also policy to adapt to climate change. Ding Xuexiang represented China at the 2023 United Nations Climate Change Conference in 2023, and may be influential in setting climate policy.
The second-largest mineral industry in the world is the mineral industry of Africa, which implies large quantities of resources due to Africa being the second largest continent, with 30.37 million square kilometres of land.With a population of 1.4 billion living there, mineral exploration and production constitute significant parts of their economies for many African countries and remain keys to economic growth. Africa is richly endowed with mineral reserves and ranks first in quantity of world reserves for bauxite, cobalt, industrial diamond, phosphate rock, platinum-group metals (PGM), vermiculite, and zirconium.
The environmental effects of transport in Australia are considerable. Australia subsidizes fossil fuel energy, keeping prices artificially low and raising greenhouse gas emissions due to the increased use of fossil fuels as a result of the subsidies. The Australian Energy Regulator and state agencies such as the New South Wales' Independent Pricing and Regulatory Tribunal set and regulate electricity prices, thereby lowering production and consumer cost.
Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005. According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.
Energy in Australia is the production in Australia of energy and electricity, for consumption or export. Energy policy of Australia describes the politics of Australia as it relates to energy.
Bauxite mining in Australia is an economically significant industry both for Australia and globally. The industry focuses on the mining of bauxite, the primary raw material for alumina and aluminium. Australia is the world's largest bauxite producer, producing almost a third of global bauxite.
China Hongqiao Group Limited is a company founded in 1994 that specializes in the production of aluminium. Hongqiao is currently the second largest aluminium producer in the world after Chinalco. It is listed on the Hong Kong Stock Exchange with stock code 1378, and is incorporated in George Town, Cayman Islands.
China's greenhouse gas emissions are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning, including coal power, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for 13 gigatonnes (Gt) or 25% of global emissions.
