In fiscal 2011, Sony launched the Green Star Program, an in-house system for assessing the environmental performance of Sony Group sites worldwide. Under the program—one of several initiatives designed to ensure achievement of the ultimate goal of Sony's "Road to Zero" global environmental plan—each site's activities are evaluated comprehensively through quantitative and qualitative assessments from four key perspectives: climate change, resource conservation, chemical substance management and biodiversity conservation.
Implementation of the Green Star Program shows how well each site is performing and elucidates their strengths and weaknesses, thus indicating what needs to be done next. The program is useful as a tool for ongoing efforts to make improvements.
Sony has developed numerical assessment criteria and measures to evaluate progress toward achieving the environment mid-term targets, Sony Group's Green Management 2015, while managing attainment levels and promoting activities for reducing environmental impacts at each site. Level of attainment is indicated by number of stars. The goal for all sites in fiscal 2015 was to earn a four-star rating (which represents a perfect score of four points in all scoring items). At the end of fiscal 2015, the average score for all sites was 3.6 points. This was because, although sites received four-star ratings in almost all of the qualitative assessment categories, there was an increase in device production volumes and recycling rate targets were not met in certain regions.
Beginning in fiscal 2016, the Sony Group launched the new environment mid-term targets, Green Management 2020. Progress against the mid-term environment targets is now indicated by up to as many as seven stars.
