"Sometimes people have the impression that the vehicle should provide some protection and that's not always the case.' " 01-06 -06-11-06 China's Coal Burning May Be Earth's Biggest Threat (New York Times) "Unless China finds a way to clean up its coal plants and the thousands of factories that burn coal, pollution will soar both at home and abroad. The increase in global-warming gases from China's coal use will probably exceed that for all industrialized countries combined over the next 25 years, surpassing by five times the reduction in such emissions that the Kyoto Protocol seeks." 06-06 -07-15-05 Judges: EPA Can Decline to Enforce Air Quality (CBS News) "An effort by a dozen states and several cities to make the Environmental Protection Agency regulate heat-trapping greenhouse gases as air pollutants was rejected Friday by a federal appeals court." 7-05 -08-15-08 China Spends $17 Billion to Reduce Olympic Smog (Time.com) "To pre-empt complaints about Beijing's typically horrendous air pollution — the Chinese capital ranks among the world's most polluted urban areas — city officials embarked on a massive cleanup operation in the months and weeks leading up to the Games." 08-08 -08-18-06 Study: Code Red for U.S. Parks (ABC News) "A new study by the National Parks Conservation Association says that one of Teddy Roosevelt's best ideas — the National Park System — is being threatened by air pollution." "One of every three of the parks is choking on pollution, the association says." 08-06 -10-04-06 Experts Challenge EPA's Position on Air Pollution (PBS News) "Pollution experts have 'serious scientific concerns' that newly unveiled U.S. air quality standards may pose risks to human health and welfare, according to a letter made public on Tuesday." "The experts, all charter members of a key advisory panel to the U.S. Environmental Protection Agency, questioned the agency's decision to keep annual standards for fine soot particles at the same level they have been since 1997." 10-06 -10-08-07 Largest Environmental Settlement in Justice Department History (CNN News) "In the largest environmental settlement in Justice Department history, American Electric Power has agreed to install $4.6 billion in equipment to sharply reduce emissions at coal-fired power plants in five states, sources said." "Government lawyers and scientists say 70 percent of sulfur dioxide emissions each year and 30 percent of nitrogen oxide emissions are produced by electric utility plants." "Environmental scientists have linked emissions from coal-fired power plants to forest degradation, waterway damage and reservoir contamination." 10-07 -11-23-06 States Are Starting to Require Clean Energy Sources (USA Today) "In Washington state, voters approved a measure Nov. 7 mandating that 15% of electrical power come from renewable sources by 2020." "That makes 20 states and the District of Columbia with such requirements, according to the Department of Energy. Two others states — Illinois and Vermont — have non-binding goals on using renewable energy sources." 11-06 -12-20-07 E.P.A. Stops Clean Air Rules of States (New York Times) "The E.P.A. administrator, Stephen L. Johnson, said the proposed California rules were pre-empted by federal authority and made moot by the energy bill signed into law by President Bush on Wednesday. Mr. Johnson said California had failed to make a compelling case that it needed authority to write its own standards for greenhouse gas emissions from cars and trucks to help curb global warming." "The decision immediately provoked a heated debate over its scientific basis and whether political pressure was applied by the automobile industry to help it escape the proposed California regulations. Officials from the states and numerous environmental groups vowed to sue to overturn the edict." 12-07 -12-20-07 New Energy Law Passed (MSNBC News) "Gas guzzlers could become relics of the past and farmers may rival oil companies in producing motor fuels under a new energy law. Consumers also will save electricity — and money — from more efficient refrigerators, furnaces and dishwashers." Editor's Note: The Bush administration has used passage of this law to nullify more stringent vehicle standards already passed by states. 12-07 -12-22-07 Bush Administration Position on Pollution Is Flawed (Time.com) "Environmentalists harbor no illusions about the Bush Administration. From a 2001 decision to weaken regulations on arsenic in drinking water to its antagonistic performance at last week's U.N. climate change talks in Bali, the White House has consistently opposed green goals. But Wednesday's move by the Environmental Protection Agency (EPA) denying California and 16 other states the right to set their own standards for carbon dioxide emissions from automobiles was an unpleasant surprise, even by Bush standards." "The EPA's Johnson argued that California's regulations had been preempted by national fuel economy legislation just been signed into law by President Bush, which requires all new cars and trucks to meet a toughened 35-mpg standard by 2020." "But that's simply not true. The new national fuel bill sets 35 mpg as a federal fuel economy floor, not a ceiling — and in any case, California officials contend that their rules would require at least 36 mpg by 2016, with room to grow." 12-07 -12-22-07 Schwarzenegger: Bush Administration Position on Pollution Is Flawed (Time.com) The federal E.P.A. agency ruled that states cannot have standards against pollution that are stronger than federal standards. California Governor Arnold Schwarzenegger: "When I look at that, the Environmental Protection Agency is the Environmental Destruction Agency. The name says it protects the environment. How can that protect the environment when you don't want to let anyone really move forward with this agenda? And [as for] the excuse that it is a national issue and therefore it must be handled at a national level — I say to myself, 'Wait a minute, let me think this through for a second,' which we always do, we think a little bit. If you have a national problem with hunger and starvation, do I say, 'Stop feeding people at the local level. We can't get involved. We have to have a policy nationally. No, we don't.' " 12-07 03-27-02 Federal Court Agrees With Tough Clean Air Standards (Washington Post - Tucker and Grunwald) Describes a court finding that upheld "the most stringent air pollution control standards in the nation's history." " 'This is a huge victory for breathers,' said Frank O'Donnell, executive director of the nonprofit Clean Air Trust." "EPA Administrator Christine Todd Whitman said her agency will support the new regulations." "The next step for the EPA is to designate the places that do not meet the new standards. Then it can start requiring states to submit plans detailing how they will get into compliance." 05-25-03 Congress Increases Tax Breaks for Polluting (MSNBC News) "Supporters including President Bush said the business equipment tax break, which was quadrupled to $100,000 in the $350 billion tax cut bill that narrowly cleared Congress, is good for the economy." "But critics called it a loophole that unfairly benefits the auto industry and provides an unnecessary perk to business people who do not need, but want to buy the largest, most-polluting and fuel hungry SUVs." 5-03 06-12-02 EPA to Relax Clean Air Requirements for Utilities (USAToday.com) Groups monitoring air pollution activity regard the new policy as very bad for the environment . "An easing of the rules, they argued, will produce millions of tons of additional pollution from older coal-burning plants and amount to a rollback of the Clean Air Act." 11-05-03 EPA to Allow Polluters to Pollute (USA Today) "The Environmental Protection Agency is likely to stop taking action against coal-burning power plants that the agency itself had accused of violating air-pollution laws, an EPA source familiar with the decision said Wednesday." "Now, it plans to use the relaxed standards — not those in place when the companies violated the laws — to determine whether the companies should be sued." 11-03 11-11-01 Agreement Reached on Reducing Pollution (BBC) Provides the conditions of a global agreement of 178 nations to reduce carbon emissions and thereby reduce global warming. The agreement, a revision of the Kyoto protocol, was developed and approved in November, 2001.

Clean Air News (Sierra Club) Provides news related to pollution of the air. 11-02 Editorial: Global Warming and Financial Interests (Grist.org - Gelbspan) "Five months after Bush's inauguration, a West Virginia Coal Association official told a meeting of the organization: 'You did everything you could to elect a Republican president. Now you are already seeing in his actions the payback ... for what we did.' " "That 'payback' came in the form of an about-face on a campaign promise Candidate Bush made in 1999 -- to repeat nationally what he had done as governor of Texas, imposing a carbon dioxide emissions cap on the state's coal-fired power plants. In a letter to four Republican senators, Bush said he was backing away from the cap because of the 'incomplete state of scientific knowledge of the causes of, and solutions to, global climate change and the lack of commercially available technologies for removing and storing carbon dioxide.' " "Particularly pleased by Bush's flip-flop was Irl Englehardt, chair of the Peabody Group, the country's biggest coal company. Englehardt had donated $250,000 to the Republican National Committee, and served as an adviser to the Bush-Cheney Energy Transition Team." 11-05 Editorial: Meet Al Gore (Time.com) "He leads from the front, and if some sheep in the family stray, he's not stressed. He's not a zealot. Leaders often shout orders; generals bark; bellicose preachers, to save our souls, get gothic on our asses. But Al speaks in measured tones. He shows slides. He has an almost embarrassing faith in the power of facts to persuade both believer and skeptic. His enduring and overarching trait is, as it turns out, the pursuit of truth ... scientific truth, spiritual truth. That — and grace. Right now, he is an America the world needs to meet." Gore: "The north polar ice cap, according to the best scientists in the world, fell off a cliff this fall. The signs that the world is spinning out of kilter are increasingly difficult to misinterpret. The question is how to convince enough people to join a critical mass of urgent opinion, in the U.S. and the rest of the world." "I think we're making progress; it's just that nothing has matched the scale of the response that is truly needed. The unprecedented nature of this crisis does make it difficult to communicate. We naturally tend to confuse the unprecedented with the improbable. But we have become capable of doing catastrophic damage without realizing it. We've quadrupled population in less than a century, amplified the power of technology many thousands of times over, and we haven't matched those changes with a shift in our thinking that lets us take into account the long-term consequences of our actions." 12-07 Papers -09-12-07 The World's Most Polluted Places (Time.com) "China's State Environmental Protection Agency says that Linfen has the worst air in the country, which is saying something, considering that the World Bank has reported that 16 of the 20 most polluted cities in the world are Chinese." 09-07 -Coal Gasification (DOE.gov) The United States generates over 50 percent of its electricity from coal plants. The USA is number one in the world in coal reserves. "A coal gasification power plant, however, typically gets dual duty from the gases it produces. First, the coal gases, cleaned of impurities, are fired in a gas turbine - much like natural gas - to generate one source of electricity. The hot exhaust of the gas turbine is then used to generate steam for a more conventional steam turbine-generator. This dual source of electric power, called a 'combined cycle,' is much more efficient in converting coal's energy into usable electricity. The fuel efficiency of a coal gasification power plant can be boosted to 50 percent or more." "Higher efficiencies translate into more economical electric power and potential savings for ratepayers. A more efficient plant also uses less fuel to generate power, meaning that less carbon dioxide is produced. In fact, coal gasification power processes under development by the Energy Department could cut the formation of carbon dioxide by 40 percent or more compared to today's conventional coal-burning plant." "The capability to produce electricity, hydrogen, chemicals, or various combinations while eliminating nearly all air pollutants and potentially greenhouse gas emissions makes coal gasification one of the most promising technologies for the energy plants of tomorrow." 10-05 50 Things You Can Do to Reduce Air Pollution (California Environmental Protection Agency) Provides 50 tips for you to improve air quality. 8-01 Acid Rain Report (UMAC - OCP) Describes the threat of acid rain. 4-02 Air Pollutants and Their Effects (Xavier) Discusses the concentrations, causes, and effects of Carbon monoxide, Carbon dioxide, Sulphur dioxide, Nitrogen oxides, Hydrocarbons, Ozone, Particulates, Lead, and Chlorofluorocarbons (CFCs). 8-01 Air Pollution (ARIC) Provides an encyclopedia of information on over a hundred topics related to the atmospheric environment and alternative energy sources. 12-00 Air Pollution (ARIC) Provides an encyclopedia of information on over a hundred topics related to the atmospheric environment and alternative energy sources. 12-00 Air Pollution (IRC and IPS - Gelbspan) "To keep earth hospitable to civilization requires 70% cuts in the world’s consumption of coal and oil and a rapid worldwide transition to clean energy" according to the Inter-governmental Panel on Climate Change, a group of more than 2,000 scientists from 100 countries reporting to the United Nations. 10-00 Air Pollution in Cities Dangerous (CBS News) "A study in the Journal of the American Medical Association says long-term exposure to the air pollution in some of America's biggest metropolitan areas significantly raises the risk of dying from lung cancer and is about as dangerous as living with a smoker."
