Comprehensive understanding of environmental impacts
To effectively cope with today's environmental challenges, we need comprehensive assessments of the actual impact of Nissan vehicles on the global environment. We have adopted an LCA* method to quantitatively measure the environmental impact over the entire vehicle life cycle (from resource extraction to vehicle disposal).
- *LCA: Life Cycle Assessment. This is a method of evaluating the impact on the environment in all stages, from extraction of the raw materials needed to make our products to manufacture, transport, use, and disposal.
Vehicle life cycle using LCA
- *ASR: Automobile Shredder Residue. ASR is what remains after material recycling is done to recover as much ferrous and non-ferrous metallic material as possible from the automobile shredder residue.
LCA results for major models
We have conducted LCAs since the early 1990s, and made quantitative comparisons to understand the environmental impact of materials that were changed in the following parts.
- Air conditioners
- Front-end modules
- Back doors
Based on the results of the LCA Project carried out by the LCA Committee of the Japan Automobile Manufacturers Association from October 1997 to March 2001, we reviewed our in-house LCA methods and calculated results for our major models.
- May 2005: Our inventory analysis was certified as being in accordance with the LCA method stipulated in JIS Q14040 by the Japan Environmental Management Association for Industry.
Models that have undergone LCA: Skyline (made in Japan), Dualis (made in England)
To develop more environmentally-friendly vehicles, LCAs are also conducted for new technologies that are introduced. These results are used to achieve the goals set out in the Nissan Green Program 2010* and the Nissan QCT-C* management policy, which clarify our environmental efforts.
- *Nissan Green Program 2010: An environmental program that establishes activity plans and specific numerical targets for Nissan to achieve by 2010.
- *QCT-C: Quality, Cost, Time - CO2. A Nissan management policy that aims to achieve higher quality at reasonable cost, shorter times, and with fewer CO2 emissions.
Life cycle CO2 emissions of Electric Vehicle Nissan LEAF
Nissan LEAF reduced CO2 emissions by approximately 40% compared with a comparable gasoline vehicle on the basis of LCA, as verified by Japan Environmental Management Association for Industry (JEMAI), a public assessment institution. Nissan continues to make efforts for further CO2 emissions reduction beyond the electric vehicles through new technologies for improving drive-train and production efficiencies.
High capacity batteries used in electric vehicles will be used not only as an energy source for driving, but also can be repurposed a storage device for mass introduction of renewable energies. Electric vehicles have an opportunity to support the de-carbonization of the society.
