How to use data to define your sustainability strategy Clear, focused data is key to implementing a strong sustainability policy, the Drapers Sustainable Fashion conference heard this morning. Disparate data Jasmine Chilton, sustainability analyst at Leaf Sustainability, explained that disparate and out-of-date data can hinder a company's attempts to address sustainability concerns: “Disparate data sources mean poor accessibility in any business, the information you need can be located in many different places and many different forms, maybe they are in spreadsheet, iCloud, Word document, or maybe you have too many sources of data.” Chilton added: "Data latency can also be a problem. The time frame of starting the process of data collection and presentation can be so long that by the time you finish the process the data is already out of data. Gold standard visibility requires continuous data collection, which will ultimately give you sustainability information you can act on.”
