Sidney, Austrália, 23 nov (Lusa) – A Câmara Baixa do parlamento australiano aprovou hoje o imposto sobre o rendimento dos recursos minerais, que prevê o agravamento em 30 por cento sobre a exploração do carvão e ferro a partir de 01 de julho de 2012.

O imposto sobre os recursos minerais, MRRT na sigla inglesa, foi aprovado na Câmara Baixa do parlamento australiano por 73 votos a favor e 71 contra, graças ao apoio de três deputados independentes e um do Partido Verde.

De acordo com o governo liderado por Julia Gillard, o agravamento do imposto contribuirá para financiar os cortes nos impostos corporativos e fundos de pensões.

Will automakers latch on to loopholes and undercut new emissions rules?

Launching its biggest environmental accomplishment, the Obama administration has proposed rules that would determine how far 2025 cars go on a gallon of gas and how much global warming pollution they emit.

Surprisingly, the auto companies support the strong rules. Even more surprisingly, though, they can dictate how successful the program will be.

This presents Detroit with an unusual challenge.

After accepting $80 billion in bailouts and demanding wide flexibility in the new environmental standards, will the carmakers act responsibly and embrace them as an opportunity for bold transformation? Or will they latch onto the loopholes they won, undercutting the rules’ benefits by building even more gas guzzlers and pushing a “bigger is better” line?

President Obama announced the broad goals, which cover new cars and light trucks sold from 2017 to 2025, in July. The administration unveiled the specific rules for reaching those targets last week, as the industry prepared for the L.A. Auto Show.

Based largely on industry information about the size and mix of the vehicles it will produce, the government forecasts a fleet that averages 54.5 mpg in 2025, and that’s been the news sound-bite. But the companies get to decide what models to make — how many trucks, how many cars, what size. If Detroit opts for bigger cars and more SUVs, pickups and vans, the mileage will be nothing near that admirable goal.

The aim also is to cut car emissions by roughly 5% a year and those from light trucks by 3.5% — on a sliding scale based on size. But the weaker truck standard, which doesn’t require significant emissions reductions until 2021, invites the manufacturers to make more trucks than cars. Similarly, if the companies make larger trucks or larger cars, the bigger vehicles qualify for weaker standards as well — reinforcing the incentive to make and sell larger vehicles and more trucks.

The decision on whether to go bigger will have the greatest impact on how much vehicles guzzle and pollute because it is size that matters most.

These loopholes and others were the price that General Motors, Ford and Chrysler demanded before supporting the emissions rules — developed by the Environmental Protection Agency, the National Highway Traffic Safety Administration and the California Air Resources Board.

The new standards’ benefits can be huge, but success is up to the automakers’ sense of corporate responsibility.

The government projects that the nation would gain between $350 billion and $450 billion in fuel savings — roughly three times the cost of the fuel efficiency technology. Consumers would pocket more than $4,000 in individual savings, even after paying the higher up-front costs for cleaner cars. If gas prices rise — and who thinks they won’t by 2025 — the savings would be even greater.

The program would save 1.5 million barrels of oil a day (the amount the United States imports daily from Saudi Arabia and Iraq) and keep more than 280 million metric tons of carbon dioxide out of the atmosphere annually by 2030. Until current politics change, cutting auto emissions is the only major step the United States will take to fight global warming.

Meeting the new goals is not a big challenge. Off-the-shelf technology, such as improved engines and transmissions and high-strength lightweight materials, along with the inclusion of a modest number of electric vehicles, would do it. The 2025 car would get roughly the mileage of today’s Prius; light-duty trucks that of the hybrid Ford Escape. Because automotive safety is a function of design and technology rather than size, the new targets can be met without compromising it.

But Detroit’s track record is not good. Congress passed the first fuel efficiency law in 1975. The standards were weaker for light trucks than for cars. Over the next three decades, industry marketers pushed trucks, as automakers sought to evade the tougher car rules. By 2004, they drove truck sales to 56% from 21% in 1975.

Gas guzzling and tailpipe pollution grew. Gas prices climbed. Foreign companies made more efficient cars, and the U.S. auto industry’s fortunes plummeted. By the American carmakers’ flawed calculus, bigger profits can come only from bigger cars: super-size them and kick up the price.

But in foreign markets, both U.S. automakers and their competitors make a profit on efficient cars sporting high-end audio, plush upholstery and other popular amenities. Why shouldn’t the Detroit Three emphasize that at home? America’s taxpayers bailed out the automakers after the companies’ irresponsible behavior landed two of them in bankruptcy. The industry — profitable again — can repay us by making vehicles that meet the most stringent targets they accepted rather than trying to exploit the loopholes.

With conscientious corporate decisions that follow the spirit as well as the letter of the program, they will help the nation fight its oil addiction, slash global warming pollution and save billions at the pump.

The automakers have the power to make the emissions and mileage program a success. They demanded to be in the driver’s seat. It is time they drive responsibly.

A divisão alemã da General Motors apresenta no salão de Genebra, na Suíça, a versão europeia do Chevy Volt, pronta pra produção. Trata-se do Opel Ampera, que combina uma motor elétrico e outro a combustão. Com visual arrojado e faróis em forma de bumerangue, o híbrido faz 60 km só na eletricidade, armazenada nas baterias de íons de lítio, o que garante um passeio isento de emissões.

Quando a carga das baterias se esgota, entra em ação, automaticamente, o motor a combustão interna, que trabalha como gerador e fornece energia ao motor elétrico. Este híbrido consegue acelerar dos 0 aos 100 km/h em 9 segundos e pode atingir uma velocidade máxima limitada eletronicamente de 161 km/h. De acordo com a fabricante, o início da produção do modelo está agendado para o final de 2011.

Tomando por base os preços atuais do combustível na Europa, a fabricante alemã calcula que um quilômetro percorrido pelo Ampera em modo de propulsão elétrica custará cerca de seis vezes menos em comparação com um veículo a gasolina convencional. A empresa estima, ainda, que o custo para recarregar completamente a bateria do automóvel durante a noite será inferior a um euro.

Japan’s science ministry says 8 per cent of the country’s surface area has been contaminated by radiation from the crippled Fukushima nuclear plant.

It says more than 30,000 square kilometres of the country has been blanketed by radioactive caesium.

The ministry says most of the contamination was caused by four large plumes of radiation spewed out by the Fukushima nuclear plant in the first two weeks after meltdowns.

The government says some of the radioactive material fell with rain and snow, leaving the affected areas with accumulations of more than 10,000 becquerels of caesium per square metre.

Last week tests found unsafe levels of radioactive contamination in recently harvested rice from the Fukushima region.

The levels of radioactive caesium were measured at 630 becquerels per kilogram, above the maximum allowable level of 500 becquerels.

Officials from Fukushima prefecture have now asked all rice farmers in the district to suspend shipments.

There have been a series of scares over radiation in food in Japan in recent months; in products such as beef, mushrooms and green tea, but never before in the country’s staple, rice.

Authorities have also begun testing soil in some Tokyo playgrounds and schools for traces of radioactive contamination.

Many people in Japan have purchased their own Geiger counters to monitor radiation levels around them.
