Research finds that certain packaging materials can show 70% lower emissions than alternatives

A comprehensive assessment sought to evaluate the potential environmental impacts of replacing polyethylene, or PE, packaging like bags, films and containers with alternative materials, including paper, glass, aluminum and steel. The findings reveal that PE packaging can have an average life cycle global warming potential, or GWP, savings of approximately 70% compared to a mix of commonly used packaging materials in the U.S. When comparing plastic packaging and alternative materials based on mineral resource use, fossil energy consumption and water scarcity, plastic packaging was generally found to have lower impacts than the alternatives.
