Producer Chris Skipper goes Backstage with Yi Ding and Hongliu Cao, chair and co-chair of the Software Water Intensity project, to discuss the development of the standard. They explore why water is a unique sustainability challenge, how data centres and semiconductor manufacturing contribute to water use, and the complexities of measuring water withdrawal, consumption, and stress. The conversation also looks at the challenges of data availability and how SWI could turn water impact into a practical metric for making better software and infrastructure decisions.
