Margo Oge, headed the Office of Transportation and AIr Quality at the U.S. Environmental Protection Agency from 1994-2012. Here she points out the contradiction in what automakers supported when the current fuel emission standards were set and today's effort by the Trump administration to loosen the standards. She also points to the contradiction between the trends in Europe, China, India, which are moving towards stricter standards and the U.S. reversing direction.  About one dozen states in addition to California have the power under the Clean Air Act to set their own standards. These states make up about one third of the U.S. market. What would result is a fracturing of the U.S. market. This would create problems for automakers as one expert recently pointed out in the NYT, that automakers should be careful what they wish for.  Automakers such as Ford say they support the current fuel emissions standards, yet call for flexibility. GM's CEO, Mary Barra, says she supports current standards. Toyota also says it supports the current emission standards. And diesel engines are now declining in Europe as a result of fuel emissions standards to preserve good air quality. History has shown the automakers have suffered badly from competition when emissions and fuel efficiency standards were lax. During the last decade the auto industry in Michigan faced decline as a result of poor management decisions and lack of foresight in pushing forward with new technologies in this field. The current recovery in the auto industry is a result of a reversal of the poor decisions made between 2000-2008, including fuel emissions and fuel efficiency, air quality decisions.    ...

California, New York and Washington are  three states, with 30 other cities in the U.S., and 100 large businesses, forming the U.S. Climate Alliance, saying they will  follow the Paris agreement on climate change. Former Mayor Bloomberg of New York City is organizing the effort, and he says in the U.S. it is cities, states and businesses that actually do the work of reducing emissions, not the federal government. Bloomberg said: "The fact of the matter is Americans don't need Washington to meet our Paris commitment." Governor Jerry Brown of California says the response will be for California and other states to set even bolder standards for reducing emissions.

The struggle between the Detroit automakers and the states over auto emissions of carbon dioxide and other heat trapping gas emissions. California adopted the first state law requiring auto manufacturers to reduce emissions of carbon dioxide in 2002 and in 2004 set standards for the emission reductions. Vermont, as well as Connecticut, New Jersey, New York and Pennsylvania adopted the same standards. Automakers sued toblock these standars in Vermont and California. While the California case is pending, Judge Sessions issued a ruling on the Vermont case this week against the auto manufacturers. This follows a decision by the US Supreme Court in April 2007 that the Environmental Protection Authority has the right to regulate heat trapping gases like carbon dioxide as air pollutants. This endorses the idea that states can set their own limits. What is needed for a state to do this is to get a waiver from the EPA, as the federal Clean Air Act has a provision that allows California to set ists own standards with a waiver from the EPA, and for other states to follow California's lead. A detailed opinion includes analysis by the Judge in this case stating why the Transportation Department's authority is limited to automobile fuel economy standards and does not carry over into auto emissions as pollutants of the atmosphere, the area of pollutants being reserved for the EPA and the individual states to work out together. Under California law as it is now emissions reductions for cars could be 30% or more below the current levels in the 2016 model year. By 2012 emissions are required to be below 2005 levels by 25% for cars and light trucks, SUV's and larger trucks 18%. Note that what is technologically feasible to accomplish in the area of auto emissions is an unknown. At the same time its a function of determination, R&D investment, collaboration between companies to pool technological and capital resources, development of engineering and manufacturing investment and knowhow to learn mass manufacture at low cost, introduction of the already feasible features quickly such as stop start engines which the Germans have already in the works for mass manufacture across product lines, and so forth. The first comer in these technologies enjoys an advantage as Honda constantly advertises itself, and the the only way to say what is technologically feasible or not is by pointing to these pioneers. In this case because of the stronger environmental movement in Europe especially in Germany, some of this pointing will be done in the direction of the German auto manufacturers progress in this direction to meet the new EU standards of 120 micrograms of CO2 per kilometre. ...

The new EPA rules for auto emission standards were setup under the Obama administration in 2012. The rules are a major part of the effort to meet the challenge of pollution and clean air. The Trump administration and EPA chief Scott Pruitt plan to reverse the higher standards. The new standards which had the support of automakers when enacted require that average fuel economy be doubled to about 54.5 miles per gallon by 2025. This would cut oil use by 12 billion barrels over the lifetime of the cars and reduce carbon dioxide pollution by about 6 billion tons.  The EPA under president Trump does not say how much the standards will be rolled back. This also leads to one more tension between California and the Trump administration. California plans to vigorously oppose the rollback. Under the Clean Air Act of 1970 California has historically made its own rules and was followed by 12 other states making up one third of the car market in the U.S. If the Trump administration is able to to this it would create two markets for automobiles in the U.S. which is not in the interest of automakers who are having second thoughts about the change. Amazingly a suburban Virginia Chevy dealership has vigorously opposed being used as the location for the EPA under the Trump administration making an announcement on this issue. Chevy dealerships are saying the Trump administration does not have the facts, that the auto industry has done very well in the last 4-5 years. Chevrolet and GM do not want to be associated with the politics on this issue. California has historically acted as a pioneer in automobile standards with the rest of the nation following. The Trump administration move would be an effort to break this precedent.  ...

This is a big desicion by the Obama administration, and has global implications for the amount of oil consumed and the emissions discharged. The Obama administration will introduce one national standard for automile emissions and mileage standards, replacing the patchwork of standards and skipping over the challenges to the California standards by using those standards to set the national rules. The rules take effect in 2012. It will create a new national standard for a car and light truck fleet in the USA, that is 40% cleaner and more fuel efficient by 2016 than it is now, with a new average of 35.5 miles per gallon. The current national standard is 25 miles per gallon, and this standard has fallen way behind the Japanese and the Europeans. The Europeans went through their battles for fuel efficiency a few years ago with auto industry resistance, and this was finally settled with tougher standards, giving the European industry advantages in technology over the Americans. The American car industry stalled higher standards, and what standards were passed were whittled down by heavy lobbying in Congress. As a result a battle raged between those interested in conservation and the environment and the Detroit car industry, especially in a deteriorating global environment for this type of prolific oil consumption on American highways. This lack of foresight on the part of Detroit carmakers, and their management, accelerated their financial collapse in 2008 and 2009, as large car and truck sales collapsed. That this tough new standard of 40% improvement in 2016, would in fact not have been possible without this fiinancial collapse and turning to the government for a bailout - with the entire board of General Motors being replaced- is one of the ironies of this situation. This decision will almost certainly accelerate the development of smaller models, and bring the kind of attention to them that will give them the quality and features and comfort to make them command higher prices and become profitable, as is the case in Europe. For too long the American small car became synonymous with being a lesser car in many dimensions of design, quality, comfort and performance, so that it became a cheap car that you upgraded from to a larger car as you became affluent. It had been that way, but did not have to be that way after the world had changed. And the larger models like the pickup trucks and large cars are more likely to be phased out with the new regulations. This will also bring a `new sanity to oil prices, as the reduced consumption in the US will accomodate the increased consumption in India from the small cars like the Tata Nano which look set to sell in the millions, and still keep oil affordable for tight budgets worldwide. In this sense it is a victory for global good sense. For President Obama this is a personal quest, as he co-sponsored 2 bills in 2006, during this second year in the US Senate, one to raise fuel economy standards, and the other to encourage the use of alternative fuels....

How the final legislation language and fuel efficiency manadated standards were worked out . At 35 mpg for the combined fleet the standard for 2020 is well behind what is seen in European Union countries and in Asian countries. The final language gives the EPA and the states like California the right to set their own standards for tailpipe emissions.

On Mercedes Chryslers efforts to bring new diesel technology to the United States. Diesels account for half of all cars sold in Europe can they make enough of a dent in the US to affect oil imports and oil prices? "Bluetec " is the European competitor to Japanese hybrid technologies, if it can be made environmentally friendly (with urea and other additives to reduce bad emissions) the its a real competitor to hybrids. The remaining task is marketing which is the challenge facing the Europeans. One bit of encouragement the new bluetec meets California emission standards.

The new diesel Jetta from Volkswagen is gointo into all 50 states and meets the ultra strict standards for emissions of California. The same is true of the European diesel Honda Accord that is coming to the USA, and the BMW 335i and other models that all run on diesel. The economics is better than gasoline per mile its 15-20% cheaper and compared to hybrids diesels offer a better deal because the premium is less and the payback period for the extra cost is faster, in the case of the MercedesE320 Bluetec diesel $1400 and 2 year payback, vs the Camry hybrid premium of $3800 and with gas at $3 per gallon 3 to 8 years for payback. And hybrids only offer buel economy but diesel offers both fuel economy and performance like the BMW 335i with 265 hp and 33mpg on highway. Because of this new attractiveness of diesel its share of the market is expected to grow to 15% in 2015 in the USA from 6% now and hybrids are expected to go from 2.2% today to 6% by then.
