This study aims to examine the effect of a training program based on Emancipatory Knowing on nurses' awareness and practices related to carbon footprint reduction in postpartum nursing care. In the first phase of the study, the carbon footprint of postpartum nursing care procedures - including those performed after both vaginal and cesarean deliveries - will be measured and compared using a validated observation-based inventory. In the second phase, nurses working in postpartum units will receive a structured educational intervention developed within the PEACE+G model framework. Before and after the training, nurses' carbon footprint-related knowledge, attitudes, and behaviors will be assessed. Findings are expected to contribute to the development of environmentally sustainable nursing practices in women's health.
