Abstract

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 production of plastics is also responsible for substantial environmental, health and socioeconomic impacts. We show that the carbon and particulate-matter-related health footprint of plastics has doubled since 1995, due mainly to growth in plastics production in coal-based economies. Coal-based emissions have quadrupled since 1995, causing almost half of the plastics-related carbon and particulate-matter-related health footprint in 2015. Plastics-related carbon footprints of China’s transportation, Indonesia’s electronics industry and India’s construction sector have increased more than 50-fold since 1995. In 2015, plastics caused 4.5% of global greenhouse gas emissions. Moreover, 6% of global coal electricity is used for plastics production. The European Union and the United States have increasingly consumed plastics produced in coal-based economies. In 2015, 85% of the workforce required for plastics consumed by the European Union and the United States was employed abroad, but 80% of the related value added was generated domestically. As high-income regions have outsourced the energy-intensive steps of plastics production to coal-based economies, renewable energy investments throughout the plastics value chain are critical for sustainable production and consumption of plastics.

  • The results are in line with previous studies and demonstrate that in 2022 little progress was made to reduce reliance on fossil-fuel feedstocks for plastic production.

    “Our results are in line with previous studies 38,39 and demonstrate that in 2022 little progress has been made to reduce the reliance of fossil-fuel feedstocks for plastic production.”

    From Complexities of the global plastics supply chain revealed in a trade-linked material flow analysis (2025) · cites this paper as [38]

    The Abstract reports substantial use of fossil resources as fuel and feedstock for plastics production in 2015, and the Discussion describes increasing use of coal as a feedstock. These findings support the background point about fossil-fuel reliance, but this 2021 paper does not establish whether little progress had been made by 2022; the citing sentence presents that as a conclusion of its own results.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
