In Japan, domestic shipments of all types of alternative-energy and fuel-efficient/low-emission vehicles in the fiscal year 2010-11 (ending March 31, 2011) totaled 3,574,105 units, according to the data provided by the Japan Automobile Manufacturers Association (JAMA). The figure represents a decrease of 453,519 units, or 11.3 percent, compared to fiscal year 2009-10.
According to JAMA, in a concerted effort to help counter global warming and improve air quality, Japan's automakers are continuously developing, and promoting the ownership of, vehicles with reduced environmental impact. Over 80 percent of shipments in the fiscal year 2010-10, comprised vehicles whose fuel efficiency met or surpassed 2010 standards and whose exhaust emissions were down by 75 percent compared to 2005 standards.
