Environmental Protection: Picking Up Speed
November 25, 2007
Here’s an article authored by me that Environmental Protection magazine just printed. Please visit their website EPOnline to get the original copy and other relevant articles on environmental issues. It also made the cover of the magazine (nice!). The article only touches upon what is happening in the automotive world, but the hope is to spark a conversation about “what cars would/should we be driving in 5-10 years, not 50 years?”.
Picking Up Speed
Hybrid engines and other new technologies are making rapid advances in controlling automotive emissions and improving fuel efficiency
By Dr. Bilal Zuberi
Nearly four decades ago, a dramatic deterioration of air quality and repeat occurrences of smog in large cities such as New York and Los Angeles led to national recognition of the growing problem of pollution from the automotive sector. As a result, Congress passed the Clean Air Act of 1970 — the first major environmental law intended to improve air quality by reducing emissions and pollutants from their sources. A key aspect of this legislation was the identification of “criteria pollutants,” specific constituents of air pollution such as ozone, sulfur oxides, nitrogen oxides and carbon monoxide, which would be monitored and controlled via additional regulations.

Emissions Reduction Progress
During the past few decades, the automotive industry has made tremendous advances in reducing pollutants in auto emissions. In some cases, such as the reduction of diesel particulate emissions in Europe, the industry voluntarily introduced new and clean technologies, but, in other cases, progress is largely a result of aggressive legislation. For example, the tailpipe emissions of hydrocarbons from gasoline cars were reduced from 10.6 gallons per mile (g/mile) in 1971 to 0.06 g/mile by 2004. In addition, smog producing NOx was reduced from 3.6 g/mile to 0.05 g/mile.
Despite those reductions, the rapid growth in car sales around the world, especially in countries with developing economies such as China and India, has increased the need for a continued decrease in automotive emissions. Additionally, now that the link between carbon dioxide emissions and global warming is firmly established (See Figure C), it has become imperative to innovate around technologies that reduce emissions and improve fuel economy simultaneously. With or without pressure from global treaties to curb greenhouse gas emissions, e.g. the Kyoto protocol, the automotive industry is positioned to accept and meet these challenges.

Over the past few days, I have received a lot of drafts of petitions and statements against the emergency rule in Pakistan…I am trying to make sense of where does the Pakistani nation stand on the current crisis. And frankly - I can’t make head or tail of it. Maybe my own knowledge is limited so I am hoping some friends here can help me understand:
As a Pakistani, whose nation exists today in a state of emergency (and the constitution stands suspended), I am indeed upset, worried, and afraid of what is next. General Musharraf is, as a friend puts it, in a kar lo jo kar na hai (do what ever you want but I am here to stay) mode where he seems to be going about the country’s business like a mad bull in a china shop. As an outsider it appears that he and the government under him are breaking all rules, thinking that once all bones of this democratic society are broken they will somehow miraculously heal themselves right.
