What is the alternative for packaging now that plastic is banned in many places? Which packaging is sustainable? Is paper sustainable, and if not, will it face the same fate as plastic? Consumers today are questioning which sustainable packaging product to consumers is eco-friendly and recyclable. Life cycle assessments are investigative tools that can help understand the multidimensional impacts of the products and their negative externalities. This can provide insights that directly inform decision-making for low-impact products and help forecast long-term sustainable development. Science must also align with our behaviour; thus, investigating our attitudes and practices can help identify factors that hinder pro-environmental behaviour.
