Over the past four decades, global plastics production has quadrupled1. [] Key Method Here, we compile a dataset covering ten conventional and five bio-based plastics and their life-cycle GHG emissions under various mitigation strategies. Our results show that the global life-cycle GHG emissions of conventional plastics were 1.7 Gt of CO2-equivalent (CO2e) in 2015, which would grow to 6.5 GtCO2e by 2050 under the current trajectory. However, aggressive application of renewable energy, recycling and demand…

Greenhouse Gas Emission Reduction Potential of European Union’s Circularity Related Targets for Plastics

Current rising concerns about environmental and climate impacts in production, consumption and end-of-life of plastics have led to efforts to switch from linear to circular economy of plastics in

Growing environmental footprint of plastics driven by coal combustion

Research on the environmental impacts from the global value chain of plastics has typically focused on the disposal phase, considered most harmful to the environment and human health. However, the

Achieving net-zero greenhouse gas emission plastics by a circular carbon economy

A bottom-up model that represents the life cycle of 90% of global plastics is developed and shows that net-zero emission plastics can be achieved by combining biomass and carbon dioxide utilization with an effective recycling rate of 70% while saving 34 to 53% of energy.

Plastics value chain - Abatement of greenhouse gas emissions

This study focuses on the possibilities to abate greenhouse gas emissions in the value chain of plastics with special emphasis on efficiency improvements in the virgin plastics production and to

Achieving negative emissions in plastics life cycles through the conversion of biomass feedstock

Plastics are one of the fastest‐growing groups of bulk materials in the world. Yet, a third of plastic waste ends up as terrestrial or marine pollution. As a strategy to lower the carbon footprint of

What material flow analysis and life cycle assessment reveal about plastic polymer production and recycling in South Africa

Global production and consumption of plastics have increased significantly in recent years. The environmental impacts associated with this trend have received growing attention internationally with

Renewable carbon feedstock for polymers: environmental benefits from synergistic use of biomass and CO2.

This work uses life cycle assessment (LCA) to quantify the environmental benefits of the combined utilization of biomass and CO2 in the polyurethane supply chain and shows how the combination reduces GHG emissions and resource use by exploiting synergies between the feedstocks.


To realize China’s target of carbon neutrality by 2060, the country’s domestic textile industry faces tremendous pressure to reduce emissions. We assessed the potential of socioeconomic conditions



Greenhouse gas mitigation for U.S. plastics production: energy first, feedstocks later

Plastics production is responsible for 1% and 3% of U.S. greenhouse gas (GHG) emissions and primary energy use, respectively. Replacing conventional plastics with bio-based plastics (made from

Uncertainty in the Life Cycle Greenhouse Gas Emissions from U.S. Production of Three Biobased Polymer Families.

GHG emissions from U.S. production of three important biobased polymer families: polylactic acid (PLA), polyhydroxybutyrate (PHB) and bioethylene-based plastics are investigated using Monte Carlo simulation.

A Review of the Environmental Impacts of Biobased Materials

Concerns over climate change and the security of industrial feedstock supplies have been opening a growing market for biobased materials. This development, however, also presents a challenge to

Plastics derived from biological sources: present and future: a technical and environmental review.

In short, petrochemical plastics are not sustainable and bio-based sustainable plastics should be developed to avoid problems caused by the petro chemical plastics.

Production, use, and fate of all plastics ever made

By identifying and synthesizing dispersed data on production, use, and end-of-life management of polymer resins, synthetic fibers, and additives, this work presents the first global analysis of all mass-produced plastics ever manufactured.

The promise of plastics from plants

Shifting from petrochemical feedstocks to renewable resources—making plastics from plants—can also rectify some environmental challenges associated with petro chemical extraction and render plastics production sustainable (see the figure).

Life cycle assessment of sugarcane ethanol production in India in comparison to Brazil

PurposeIndia’s biofuel programme relies on ethanol production from sugarcane molasses. However, there is limited insight on environmental impacts across the Indian ethanol production chain. This
