Nissan Motor to Cut CO2 Emissions by 40% for 2015 Models

Keywords: Climate Change Manufacturing industry Transportation / Mobility 

At a technical press conference on March 15, 2006, Nissan Motors Co. announced that they had set a technical development target to cut carbon dioxide (CO2) emissions in 2015 models by 40 percent from 2005 levels. According to the Intergovernmental Panel on Climate Change (IPCC), the world needs to stabilize the atmospheric concentration of CO2 at 550 ppm in order to limit the long-term increase in average temperature to two degrees Celsius. Based on the scenario, Nissan has specified a target value assuming that by 2050 a 70 percent reduction in new vehicles' CO2 emissions from the 2000 level is necessary.

Nissan's efforts to reduce CO2 emissions are categorized into three areas: vehicles, driving aids and traffic environment. In terms of cars, the company aims to reduce CO2 emissions by 30 percent by developing new technologies for gasoline engines to improve cycle efficiency, reduce pump loss and reduce friction loss. Another effort is to expand the gear range of continuously variable transmission (CVT) and to increase the number of vehicles equipped with the CVTs. To facilitate the spread of electrically-driven vehicles, the company will strive to develop motors, batteries and inverters that are compact, light-weight and inexpensive.

In terms of people, Nissan will support energy efficient driving to achieve a seven percent reduction in CO2 emissions. The company believes that introduction of eco meters to check fuel efficiency and probe information systems that provide data on location and speed using wireless communication technology will help eliminate variations in fuel efficiency among drivers. In terms of transportation infrastructure, the probe information systems will avoid and ease traffic jams, and thus the company also believes that they will contribute to reducing CO2 emissions.
