It involves engaging consumers through awareness-raising and education on sustainable consumption and lifestyles, providing consumers with adequate information through standards and labels and engaging in sustainable public procurement, among others. This is the official text of SDG 12 of the United Nations declaration about the Sustainable Development Goals 2015 - 2030.
For this purpose the international guidelines for sustainable production and consumption ISO 26000 and especially the follow-up of these guidelines the newly introduced ISO 20400 about dialogue in the supply chain are providing the information infrastructures for dialogue (presentation January 2017 - official publication May 2017).
