Largest online fashion retailers like Zalando, About You, and Yoox Net-a-Porter are launching a sustainability platform for brand partners. Zalando has 48 million, About You 30 million and Yoox Net-a-Porter has 5 million customers. The initiative would offer a learning programme as well as a place of interaction between brands and sustainability experts. It is going to focus on how to measure emissions and set climate goals in alignment with Science Based Targets. At first, a pilot with selected partners is set to start this year and in 2023 it would launch for all collaborators. The fashion industry is responsible for 10% of global emissions. Zalando contributes majorly with 5-6 million tons of CO2 per year which comes from its 4500 brand partners. It aims for 90% of them to have science-based targets by 2025. The collaboration of the 3 companies can drive a more insistent campaign toward reducing emissions in the fashion industry.
