Nanomaterials have been used for automotive applications, namely for safety and energy consumption reduction purposes. It must be emphasized that the vehicles' weight decrease is a balanced result between the application of nanomaterials and the use of structures made from low-density materials. Nanotechnology will allow a more efficient use of materials, as well as energy and therefore will reduce waste and pollution. For example, by using a very small amount of precious metals on carrier material of exhaust emission catalysts the emissions of hydrocarbons, carbon monoxides and nitrogen oxide could be reduced by 90%. Therefore, nanotechnology developments for automotive applications should be considered when developing future policy scenarios and strategies and to develop eco-innovative and safer strategies. Life cycle awareness for nanotechnology is currently in its beginning, and amongst other concerns potential impacts of nanoparticles are so far not well understood due to the complexity of these materials. There are still open questions regarding the effects of nanomaterials on human and ecological exposure. Potential advantages and improvements of nanotechnology are currently promoted disregarding the potential environmental impacts along the entire life cycle which should be assessed and diminished in total and not only for specific aspects in product use and consumption. In application cases where nanoparticles are released intentionally or accidentally the lack of reliable knowledge about potential impacts and risks impede a straightforward promotion of proven advantages. There is the need to develop knowledge in the context of the manufacturing process to overcome the gaps of the producing process, including the raw materials being used and recycling scenarios could be helpful for comparative assessments of nanotechnology by means of LCA. Also, new nanocompounds and materials should be managed by LCA analysis to measure improvements, projections, risks and advantages of taking into account the full life cycle. There is also the need of quantitative assessment of differences in the uptake and toxicity of chemically modified nanoparticles. LCA exercises are crucial to health effects of nanotechnology and LCA reports need to be made for different classes of nanoparticles and nanoproducts, so as to predict the real threat of nanowaste. However, at present, it is impossible to obtain a full-spectrum LCA for nanotechnology due to insufficient knowledge about the detailed inputs and outputs of the system. Risk assessment and LCA must be applied to nanomaterials analysis in order to allow the development of products and services without compromising the environment from one of the most exciting and multidisciplinary fields, nanotechnology. Future research need requires the development of the following areas: develop procedures for product end-of-life analysis, develop analysis risk for human health and ecossystems effects from nanomaterials, as well as human exposure to nanoparticles from vehicle emissions, materials, technologies and processes for sustainable automotive electrochemical storage applications and electric and hybrid vehicles (advanced eco-design and manufacturing processes for batteries). Nanotechnology holds a great promise to achieve environmental, economic and safety goals in the automotive industry; however, researchers, governments and industry must promote a common procedure to optimize LCA in the decision support and to transfer significant information in the nanotechnology and product development.
