Do you know where your money really goes? A new app aims to help consumers avoid companies and products they don't even realize they're investing in. People can create campaigns or join existing boycotts. For example, a campaign identified in the app asks consumers to avoid Koch Industries. More than 8,000 people have pledged to boycott the company, which is owned by conservative billionaires Charles and David Koch. Buycott helps consumers do this by untangling a long trail of associations and relationships among companies. For example, sales of Brawny paper towels accrue to Koch Industries because Koch's subsidiary, Georgia-Pacific, produces the towels. Consumers may not be aware of those connections while casually browsing supermarket shelves. The Buycott app scans barcodes and then traces products to their parent companies. The app checks that the product doesn't already run afoul of boycott campaigns the user has joined. If someone joins the Local & Sustainable Food Initiative through Buycott, for example, they can scan barcodes at the supermarket to make sure their food really is coming from a local source. The app can even tell you if a certain food product contains GMOs. One campaign pushes buyers to boycott companies, including Monsanto, that fought against putting GMO labels on food. The app isn't perfect though. As Buycott admits, Corporate ownership structure is always changing and can sometimes be complex." The app allows users to add their own knowledge of products not yet part of the database, making Buycott more accurate as more people download and contribute to it.
