Shipping Industry Resistant to Becoming Greener. By James Kanter, NYTimes, April 26, 2008. "Despite the growing availability of cleaner technologies, the shipping industry has made little progress toward becoming greener, even as traffic grows heavier on existing routes and new routes open up in the Arctic. Indeed, the most recent efforts to tackle the problem have met resistance -- less from the shipping industry, however, than from the big oil companies that supply the dirty fuel. Shipping is responsible for about twice the emissions of carbon dioxide as aviation -- yet airlines have come under greater criticism. Particles emitted by ships burning heavy bunker fuel, described by some seafarers as 'black yogurt' for its consistency, also contain soot that researchers say captures heat when it settles on ice and could be accelerating."
