PurposeThis study aims to evaluate corporate sustainability integration by evaluating corporate practices against the sustainability principles of inclusivity, materiality, responsiveness and impact outlined in AccountAbility’s AA1000 Accountability Principles (AA1000AP) standard.Design/methodology/approachData comprise 12 semi-structured interviews with senior managers of listed New Zealand companies. Findings are evaluated against AccountAbility’s principles of inclusivity, materiality, responsiveness and impact, which are based on a normative view of stakeholder theory.FindingsIn terms of inclusivity, stakeholder engagement is primarily monologic and is directed more towards traditional stakeholder groups. However, social media, which is gaining popularity, has the potential to facilitate greater dialogic stakeholder engagement. While most companies undertake a materiality assessment (with varying degrees of rigour) to support sustainability reporting, only some use it to drive planning and decision-making. Companies demonstrate responsiveness to stakeholder concerns through corporate governance and sustainability initiatives. Companies are monitoring and measuring their impact on stakeholders using sustainability key performance indicators (KPIs). However, measuring traditional metrics is easier than measuring areas such as the community. In rare instances, the executive’s remuneration is linked to these sustainability KPIs.Practical implicationsThe study findings offer useful examples of the integration of sustainability into corporate processes and systems. Practitioners may find the insights useful in understanding how sustainability is currently being integrated into corporate practices by best practice New Zealand companies. Regulators may consider incorporating AA1000AP into their corporate governance guidelines. Finally, academics may find the study useful for teaching business and accounting courses and to guide the next generation of business managers.Originality/valueFirst, the study brings together four streams of research on how sustainability reports are prepared (inclusivity, materiality, responsiveness and impact) in a single study. Second, the findings offer novel insights by evaluating corporate sustainability against the requirements of a standard that has received little academic attention.
