Wastewater Impact Assessment Tool (WIAT)

This tool from WBCSD can help you to undertake site-level assessments of pressures and changes on the state of nature and the impacts on climate, biodiversity, and water security resulting from industrial wastewater (water quality) and water use (water quantity). The tool uses wastewater treatment and water use data at a site level to calculate impact and levers of action for three key indicators: water quality, water availability, and GHG emissions. WIAT also pulls in and overlays contextual data from other global data sources to further highlight changes in the state of nature within a local context. WIAT is aligned with CDP and GRI, and the outputs of the tool are aligned with the SBTs for nature methodology. This tool will be of particular benefit to professionals tasked with setting science-based targets for nature.
