A Comparative Analysis of the Environmental Impacts of LDPE Plastics and Various Widely Used Plastics in the United States

Plastic production has emerged over the decades as one of the worlds most significant contributors to carbon emissions. The most popular plastic types in the US, PET, HDPE, LDPE, PVC, PP, and PS, were calculated to have 208 million metric tons of carbon dioxide equivalent (CO2e) in 2022. LDPE was the top contributor among these plastics, producing 72.6 million metric tons of CO2e. This study evaluates the climate impacts of various plastics, comparing them based on production volumes and associated CO2 emissions. The life cycle of plastic production released 232 million metric tons of CO2 in 2021. Plastic waste incineration and anaerobic decomposition in landfills further exacerbate CO2 and methane emissions. With plastic consumption quadrupling over the past 30 years, only 20% of plastic waste is recycled or incinerated, while the rest contributes to environmental pollution. Policymakers can mitigate plastic production's environmental impact by promoting recycled paper packaging, switching factories to renewable energy, and raising public awareness to boost climate activism. Implementing these measures can significantly reduce CO2 emissions and combat climate change.
