Mariko has already conducted materiality analysis and placed ESG into Fujitsu’s corporate strategy. But she needed to go further than that.

It also helps to cascade ESG awareness all the way from executive level down to individual employees.


She builds management team level support to ensure that everyone understands how important ESG is, and stakeholders are engaged in helping create the strategy.
