What is Water Index (Extended)?
The Water Index (Extended) is a metric designed to quantify the total impact of water across a company’s value chain, encompassing both direct and indirect water usage. It extends beyond simple water consumption figures by factoring in water quality, scarcity, and the associated risks and opportunities related to water management.
This index provides a more holistic view than traditional water footprint calculations. It aims to capture the environmental, social, and economic dimensions of water use, offering a sophisticated tool for sustainability reporting and risk assessment. By considering the extended aspects, businesses can better understand their water-related dependencies and potential vulnerabilities.
The development of such an index is driven by increasing stakeholder demand for transparency regarding environmental impacts and the recognition of water as a critical finite resource. Companies utilizing the Water Index (Extended) can demonstrate proactive water stewardship and identify areas for efficiency improvements and responsible resource management.

Understanding Water Index (Extended)
Understanding the Water Index (Extended) requires looking at its constituent parts and their interplay. It moves beyond a single numerical output to analyze the complex web of water interactions a business has with its environment and society. This involves mapping water flows from raw material sourcing, through production processes, to end-of-life disposal, and considering the context of each location’s water availability and quality.
Key components often include direct operational water use, indirect use embedded in the supply chain (e.g., water used to grow agricultural inputs), and the impact of wastewater discharge on local water bodies. The
