Air Pollution In Australia Essays - Fuel Gas, Energy Economics Air Pollution In Australia 1. Identify current trends, scale and likely future sources of carbon monoxide, sulphur dioxide, nitrogen dioxide, lead, particles and photochemical oxidants..... AGA notes that considerable background material is already available on this issue including the State of the Environment Report and other processes being developed through the NEPC. It is important that reporting by the Inquiry take account of existing material. 2. Identify and evaluate management options for each of the identified pollutants, including options which address one or more pollutants together, which will lead to improved urban air quality in the medium (5-10 years) and longer (10-15 years) term. Alternative transport fuels It is widely recognized that use of gaseous transport fuels liquefied petroleum gas (LPG) and natural gas for vehicles (NGVs) can assist in improving urban air quality. In response to the Federal Government's development of a national Sustainable Energy Policy for Australia, the AGA, the Australian Liquefied Petroleum Gas Association and the Australasian Natural Gas Vehicles Council released a report in January 1997 titled Gaseous Transport Fuels Policy Development (copy attached). The submission indicates that motor vehicles account for over 80 percent of carbon monoxide, 45 percent of hydrocarbons and 67 percent of nitrogen dioxide emissions. It also notes that Australia's transport sector is a major contributor towards the energy sector's greenhouse gas emissions. Wider adoption of gaseous transport fuels would have substantial benefits in reduced carbon monoxide, nitrogen oxide, sulphur dioxide, lead and particulate emissions. Gaseous transport fuels also lead to reduced carbon dioxide emissions. A report prepared for the AGA (to be published as an AGA Research Paper) indicates that: NGV tailpipe emissions of carbon monoxide are between 49 and 99 percent lower than from gasoline vehicles; and new generation LPG systems can reduce oxides of nitrogen by 50 percent. The AGA believes that urban air quality would benefit from wider introduction of gaseous transport fuels. Urban transport vehicles based on LPG and NGV can lead to improvements in air quality in the medium and longer term. This includes use of LPG and NGV in trucks, light commercial vehicles, buses, taxis, business and government fleets and private cars. The Joint Industry Submission on Gaseous Transport Fuels emphasizes that Australia's gaseous transport fuels industry is still developing and that the industry and users need confidence in the maintenance of Federal petroleum product excise exemption policy, before making multimillion dollar infrastructure and conversion investments. The submission sets out other measures aimed at ensuring wider adoption of gaseous transport fuels. Appliance approvals Natural gas is expected to increase its share of the market in the residential, commercial and industrial sectors. The market opportunities have been analyzed in the Gas Industry Development Strategy 1995-2000, released by the AGA in November 1995 (copy attached). Much of this increased demand will be in urban areas. AGA's Environment Policy recognizes the role of appliance standards and Codes and includes a commitment to: maintain the environment as a high priority in the industry's own technical codes, standards and equipment approvals which include relevant performance, efficiency and energy labeling criteria in order to have continuous improvement in environmental performance meeting both government requirements and community expectations. The AGA Approval Schemes provide for the testing and approval of a range of residential, recreational, commercial and industrial appliances, to meet the standards of Codes prepared and published by the AGA. The Approval Scheme covers natural gas, towns gas and LPG and includes emission standards appropriate to the type of appliance concerned. 3. Are cognizant of the capacity of existing and proposed strategies and arrangements, at all levels of government, to reduce air pollution in the identified time frame; of Australia's longer term objectives in relation to greenhouse gas emissions, sustainable energy policy and international competitiveness; of the economic, social and environmental costs of urban air pollution and of any identified management options; and of the need to identify options which can be undertaken by governments, industry and the community. The Inquiry's terms of reference recognize the need to integrate environmental objectives with wider policy objectives including economic, greenhouse and sustainable energy policy. As part of the Gas Industry Development Strategy, the AGA commissioned an independent report on the economic and environmental contribution of the natural gas industry to the Australian economy. This research concluded that a growing natural gas industry contributes positively to both the economy and the environment. The report examined the implications of attaining the AGA growth goal (ie that the share of natural gas in Australia's primary energy consumption reaches 20 percent

The Truth Behind Those Megalodon Documentaries

The Truth Behind Those Megalodon Documentaries What can you say about a TV documentary in which the suspiciously good-looking lead protagonistmarine biologist Collin Drake- comes up empty in a Google search? Or, for that matter, his equally attractive marine biologist pal Madelyn Joubert, who joins him halfway through the show, and whom a cursory web search easily demonstrates not to exist? And, not to belabor the point, a TV show that starts with suspiciously staged-looking video footage of a charter boat capsizing off the coast of South Africa, and no references can be found about this accident (in which three passengers were supposedly killed) from reliable online news sources? I dont know much about charter boats, but I do know that people whose ship is in the process of sinking do not take the trouble to center their subjects on frame. (See also 10 Things Megalodon Could Swallow Whole, a review of Megalodon: The New Evidence, and an article explaining why there are no giant sharks alive today.) Welcome to the world of the Discovery Channel and its inaugural Shark Week special, Megalodon - The Monster Shark Lives, which first aired on Sunday, August 4, 2013.  I usually steer well clear of Discovery programming, but since I know more about Megalodon than the average person (see my articles 10 Facts About Megalodon and Megalodon vs. Leviathan - Who Wins?) I felt compelled to tune in. Im shocked that a major TV channel with a supposedly educational purview can get away with this drivel, in which Collin Drake (whoever he is in real life) pursues his theory that that charter boat was rammed by a living Megalodon. Were taken through various pieces of evidencesonar sightings, Nazi-era photographs, whale carcasses washed up on the beachbut if Discovery is brazen enough to manufacture its talking heads out of whole cloth, what is the point of assessing the reliability of these details? I dont want to get into a debate about whether real, live Megalodon sharks are prowling the shores of southern Africaafter all, its impossible to prove a negative, and people will believe what they want to believe. On first airing, I was also willing to entertain the teensiest bit of doubt that Collin Drake and Madelyn Joubert were who they said they were (though they certainly looked, acted and talked unlike any scientists Ive ever met in real life, a judgment confirmed when it was later revealed that Collin Drake was actually played by a third-string Australian soap actor.) But I am saddened by the prospect that millions of unsuspecting people allow themselves to be educated by the Discovery Channel, which apparently cant stoop low enough to procure its ratings, and doesnt care how many schoolkids it misinforms in the process. Say what you will about Megalodon, but it couldnt help being a soulless, uncaring killing machineyoud think someone at the supposedly more evolved Discovery Channel would have a conscience! (Apparently unashamed by the critical backlash against Megalodon: The Monster Shark Lives, Discovery aired an even more egregious sequel, Megalodon: The New Evidence, in July 2014, about which you can read in Megalodon: The New Evidence - Dont Believe Everything You See.)
