Developments in corporate water accounting and accountability

In decades since the Rio Summit, freshwater has become an increasingly prominent issue in the global arena and attention has turned to the role of the corporate sector. Various (predominantly voluntary) corporate water accounting standards currently exist, from water-related components in wide-ranging sustainability standards such as the Global Reporting Initiative through to standards specifically focused on water and/or a particular industry. While academic research on adoption of these standards is sparse, initial findings reveal generally poor water reporting in terms of both quality and quantity. In future, the major areas where reporting (and standards) could be improved are the provision of site-level water information and the assessment of water risk throughout the supply chain.
