Economic and environmental impacts of commercial milk formula in Indonesia: estimates and comparisons using the Cost of Not Breastfeeding, Green Feeding, and Mothers’ Milk Tools

Breastfeeding's economic importance to Indonesia far exceeds the retail value of CMF sales. Displacing breastfeeding carries high but largely undocumented economic and environmental costs. Losses are greater when measured as a food resource than as health costs, lost lives, or cognitive decline. Environmental impacts based on sales data are higher than those from survey data. Our findings and the discrepancies between tools reveal a critical gap in national statistics and highlight the need to recognise breast milk as an economically valuable, healthy, and sustainable national resource in Indonesia.
