Understanding the water-energy-carbon nexus in water supply is essential for regulators and utilities. This study employs a non-radial Data Envelopment Analysis (DEA) model to assess eco-productivity (ecoP) change, synthetic indicator that integrates carbon emissions, energy costs, delivered. It also evaluates its components—eco-efficiency change eco-technological change—across companies England Wales from 2011 2018. The analysis reveals an annual improvement ecoP of 1.1%, driven by 2.1% gain eco-efficiency but offset 1.0% decline technological advancement. reduction GHG emissions emerged as most significant positive contributor, enhancing 3.22% annually, while costs detracted –0.09%. results underscore negative impacts increased delivery (–1.74%) number connected properties (–1.27%) on ecoP, highlighting need demand management policies.
