NAT.B10.EB Discharge Water Quality Management
About the data
This metric was designed by The World Benchmarking Alliance, more information can be found here. Sources and Alignments for each indicator can be found here as well as the scoring guidelines here
The World Benchmarking Alliance's Nature Benchmark measures and ranks the world's most influential companies on their efforts to protect our environment and its biodiversity.
This metric relates to the Indicator: The company reduces water quality pressures across the most material parts of its value chain.
Rationale: Approximately 80% of global wastewater is untreated when released back into the environment, causing significant negative effects on both ecosystem functioning and human health (IUCN, n.d.). This indicator is aligned with the SBTN interim target to reduce water quality pressures in high-impact parts of the value chain in line with good ambient water quality by 2030.
Methodology
WBA analysed all publicly available group-level disclosure in English on the applicable group website, which was predominantly annual reports and sustainability reports. Draft assessments were then sent to each company inviting them to provide feedback. This feedback could include additional publicly available group disclosure published. These were then reviewed and finalised. Final assessments were then shared with each company before being published online.
For this metric the company must describe what the process involves or refer to external certifications they follow (such as ISO). Disclosure of having a process alone is not enough to score.
