That soupy brown air is the result of so-called black carbon expelled into the atmosphere in and around the Indian capital, from the burning of biomass for cookstoves and of black coal for electricity, and the incomplete combustion in the old diesel engines that propel most of the cars and trucks in the city. Breathing here isn't all that good for you - there's a reason the city is home to the "Delhi cough" - and now scientists are discovering that the sooty air isn't good for the climate either. According to some estimates, black carbon...
...with an overall slide of 26.7% for all luxury cars. Still, Johan de Nysschen, president of Audi's U.S. division, says the company can't afford to ride out the recession without making changes - it needs to continue to innovate. That is why Audi is pushing forward with clean-diesel technology, which de Nysschen believes is the quickest way to get fuel-efficient, less-polluting cars on the road. He spoke to TIME about Audi's recent economic performance, his feelings about electric vehicles and what kind of car he would most like to have in his garage...
...Audi is instead touting the benefits of diesel technology. How do you get around the negative perception of diesel cars in the U.S.? Clean-diesel technology represents an immediate technological leap - you immediately, very significantly, reduce fuel consumption and emissions. Biodiesel, too, could get you very close to the point where you can have a neutral carbon footprint. This can all be attained in a relatively shorter space of time, and at lower costs, than waiting 20 years-plus until we get our act together with electric cars. I should say, though, that hybrids are important. It is not diesel...
...Given the driving patterns of most American consumers, which is more likely to be suburban travel, clean diesel has advantages. Because this technology holds so much promise, it's our task to inform the public and policymakers because it's clear that public [opinion] will have to embrace all available technologies to move things forward. I also listen to all of our dealers, and it's very clear that those consumers who are informed about the technology have really embraced it with great enthusiasm.

...Though shipping is still the most resource-efficient way to move containers, large ships use some of the dirtiest fuel on the planet. Ships' bunker fuel is a thick, black sludge leftover from the refining process and has about 2,000 times the sulfur of regular diesel fuel. When bunker fuel burns, it releases a host of toxins, including sulfur oxides and nitrogen oxides, that can lead to respiratory problems and acid rain. Now a better understanding of the health impact of shipping and commercial boats - combined with high oil prices and tighter general pollution restrictions - is sparking what could...
