The producers can use the platform to promote local products to form a long-term sustainable consumption.The website of the d: platform has a culture board to attract designers to work with local production and make the public know the unique local products, culture, and lifestyle.The app of d: has an intercultural design tool to enable a global team to use the intercultural advantage to do innovation effectively with local production as part-time.
