LONGER LASTING LUB OIL REDUCES SHIP EMISSIONS, COSTS

摘要

However, because there are far more ships than planes, shipping still contributes an estimated 1.15 billion tons of CO_2 annually, or almost 4.5% of global emissions of the main greenhouse gas. In comparison, the aviation industry is responsible for 650 million tons of CO_2-half that of shipping. Further, it is suggested by most studies that shipping emissions are set to become the biggest contributor of manmade CO_2 after cars, housing, agriculture, and industry. In short, it's vital that the ship-ping industry cleans up its act.
