This document discusses the environmental impact of single-use glass packaging, which has a higher carbon footprint compared to alternatives like plastic and metal. It argues for prioritising reusable glass to reduce carbon emissions and lessen environmental harm. The report critiques the European Commission’s Packaging and Packaging Waste Regulation (PPWR) for exempting single-use glass from several circular economy requirements, such as deposit return systems, thereby giving it an undue advantage. Recommendations include setting stringent reuse and recycling targets specifically for glass, equalising deposit-return system rules across all materials, and implementing high recycled content standards to encourage glass circularity. The EU is urged to lead the shift towards reusable glass in packaging policies, supporting a more sustainable, low-carbon future.
