Urban air pollution is a major issue of concern today. One source is attributed to vehicle exhaust emissions, including carbon dioxide (CO2), hydrocarbon (HC) and nitrogen oxides (NOx). Nissan has taken vigorous steps to protect the environment during vehicle use, such as by improving fuel economy and reducing exhaust emissions. At the same time, Nissan is also developing a wide range of technologies -- from low-emission engines, direct-injection engines and CVT technologies featured in current models, to the future technologies such as Hybrid and Fuel Cells -- aimed at reconciling these issues with the inherent capability of vehicles to provide driving pleasure. Because of their outstanding CO2 reduction, zero-emission performance, and freedom from fossil energy, Nissan regards fuel cells as one of the alternative technologies as a power source for vehicles. However, significant improvements are necessary in terms of cost and practical use before envisioning real mass production. Nissan has embarked on a 5-year program with Renault to develop fuel cells as the ultimate clean power plant. Currently, Nissan is testing an Xterra-based fuel cell vehicle under real world conditions as part of the California Fuel Cell Partnership program. In North America, Nissan’s operations include automotive styling, engineering, consumer and corporate financing, sales and marketing, distribution and manufacturing.
