Sony conducts research aimed at developing proprietary technologies that contribute to the reduction of environmental impact and can be applied to new products and services, as well as to manufacturing processes. We first determine a research theme that will contribute to the reduction of our environmental footprint, in line with our medium-term environmental targets. We then conduct basic research at one of our headquarters technology centers. Finally, we transfer the practical applications of this research to our operating divisions. An example of Sony's research involving proprietary technologies can be found at its Advanced Battery Development Center, which was established in fiscal year 2009 to develop and commercialize storage batteries for automotive and industrial applications.

In fiscal year 2009, Sony designated "energy and the environment" as core R&D themes and resolved to invest decisively. Principal areas of endeavor include energy-related technologies, namely those for power generation and storage battery devices; materials technologies that help reduce resource consumption; and information and media technologies that support environmentally conscious lifestyles.
