Sony regularly establishes Sony Group mid-term environmental targets and maintains strict control over the chemical substances it uses. To do so, Sony specifies the chemical substances to be controlled and the manner of their use in the manufacturing process and in the finished products, and fully understands the regulations and laws in the relevant countries and regions to comply. In addition, Sony controls chemical substances that may not be controlled by laws, considering the magnitude of effects of chemical to the environment. In line with the precautionary approach, Sony takes steps whenever possible to reduce, substitute and eliminate the use of substances that have potentially significant impact on the environment even in the cases where scientific evidence is not fully proven.
