The prevalence of unsustainable fashion consumption practices of Gen Z and Millennials highlights the urgent need for targeted interventions. This research explores the impact of philanthropic and economic motives on clothing disposal behavior among Gen Z and Millennials in Metro Manila, Philippines. Using a descriptive causal research design, the proponent surveyed 119 young adults to understand their clothing disposal habits. Multiple linear regression was employed to study the effects of personal norms, social norms, and environmental awareness on sustainable fashion consumption and how it influences philanthropic clothing disposal behavior and economic clothing disposal behavior. A moderation test adapted from Baron and Kenny (1986) was used to assess the moderating effect of facilitating conditions. Findings reveal that personal norms, social norms, and environmental awareness have a significant impact on sustainable fashion consumption. Consequently, sustainable fashion consumption has an influence on philanthropic and economic disposal behavior, while facilitating conditions did not moderate this relationship. The study provides valuable information for creating business models that promote sustainable disposal solutions and offer practical insights that motivate businesses and organizations to adopt more sustainable clothing disposal habits. It can revolutionize sustainable practices within the Philippine fashion industry, positioning businesses and organizations as pioneers in sustainable fashion practices while contributing to a more environmentally conscious and economically viable fashion ecosystem.
