Environmental degradation and unsustainable consumption have become urgent global issues, with consumer behaviour responsible for nearly 70% of all greenhouse gas emissions. Although awareness of eco-friendly lifestyles has grown, the actual use of green products remains low. This research uses the Quality Function Deployment (QFD) method to identify and rank consumer preferences for environmentally sustainable products. Unlike previous studies that examined individual features separately, this work combines consumer perception data from the Delhi National Capital Region (NCR) with expert industrial evaluations to close the gap between design and policy implementation. The findings show that consumers value non-toxic, biodegradable, and recyclable materials most, followed by accessibility, emission reduction, and clean energy use. The study offers a structured QFD-based prioritisation model that converts consumer preferences into practical design guidelines for sustainable product development. Policymakers and manufacturers in emerging economies can replicate this framework to align environmental objectives with consumer demands better.
