Increased business complexities coupled with enhanced global transformation have propelled corporations to behave as responsible citizens to drive the sustainability agenda. Many corporations incorporate their affirmative commitment to sustainable business practices into their corporate identities and give evidence for this in their sustainability reports. This paper examines the role of the board of directors in sustainability reporting quality (SRQ) in the Asia‐Pacific region. Based on a cross‐sectional study of 113 companies from 12 countries in the region, we find that the SRQ in the region leaves much room for improvement. However, we find that the institutionalization of the concept of corporate social responsibility (CSR) in an organization provides a sound foundation for enhancing SRQ. We find that the value of CSR anchored in the vision and/ or mission statement and strategic alliances fostered with non‐governmental organizations are positively associated with SRQ.This study contributes to strengthening the understanding, promoting discussion on the state of sustainability reporting in the Asia‐Pacific context and laying a solid foundation for more aggressive efforts to enhance SRQ. The study identifies the significant drivers currently associated with SRQ. The weak role of the board of directors in upholding the sustainable development agenda through the reporting process is highlighted. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment.
