Why do we need “Materiality”?

Rigaku group has upheld the corporate mission of its founders to “contribute to the enhancement of humanity through the development of science and technology,” working with the motto to “Value our customers, value our people, and value our technology.” Now the global environment issues including climate change, inappropriate management of resources, and loss of biodiversity affect our daily life and sustainability of society and economy. Based on that, Rigaku group specified our “Materiality” to contribute to realize the sustainable world and keep developing and growing with our customers through our business activities. We integrate this materiality into our mid-to-long term strategy and execute on this through our business.

Process for specifiying sustainability related materiality

  1. Identify a pool of potential social issues

    Create a long-list of "societal issues" for evaluation with reference to GRI standard, SASB, UN SDGs, and other international guidelines. Tailor the list adding some further items specific to Rigaku’s business and profile.

  2. Individual executives’ views on materiality gathered in survey

    Conduct and collate a survey of "important social issues for my company" with around 40 key people. Survey respondents are executive officers and above and based worldwide, including independent directors/auditors. Also, prepare reference data about competitors and guidelines information to provide an external view.

  3. Executive management group’s opinions on materiality consolidated at ESG Steering Committee

    Based on the survey results, discuss the most prominent social issues at the ESG Promotion Committee and build the final Materiality matrix for presentation to and endorsement by the Board of Directors.
    KPIs were set in line with the Materiality, also approved by the Board.
