Reporting is an essential instrument for organizations to understand the impacts of their decisions and operations on people and the planet. Addressing the most serious corporate impacts on sustainability by means of reporting effectively creates an accountability mechanism that helps organizations embed critical issues such as human rights into their business practices and at the core of their strategy. Through the means of reporting, organizations identify their sustainability risks and impacts and are encouraged to be accountable for them. Reporting contributes to internal awareness and understanding of possible negative impacts, as well as the means to mitigate them while maximizing the positives. This accessibility of information enables informed decision-making by stakeholders, including civil society, investors, customers and regulators. Consequently, businesses are more inclined to avoid or limit negative impacts and hence strive to improve performance. Ultimately, effective reporting plays an important role in a company’s success, as it responds to its stakeholders’ needs for transparency and information. This chapter presents an overview of the sustainability reporting process, draws lessons from current practices on human rights reporting, and provides recommendations for (future) practitioners, presenting a snapshot of current challenges and practical thinking.
