ClearGlobal environmental plastics dispersal under OECD policy scenarios towards 2060
Researchers modeled how global plastic pollution would spread through the environment under different policy scenarios developed by the OECD, looking ahead to 2060. They found that even with ambitious policy action, significant amounts of plastic will continue leaking into aquatic environments unless waste management improves dramatically worldwide. The study suggests that coordinated global policies targeting both plastic production and waste management are essential to curb environmental plastic pollution.
Projections of plastic leakage to the environment to 2060
This review examines projected trends for plastic leakage to terrestrial and aquatic environments through 2060, finding that without intervention, plastics use and waste generation are expected to triple, substantially increasing environmental contamination and associated impacts on ecosystems and human health.
Global environmental plastic dispersal under OECD policy scenarios toward 2060
Using a global computer model, researchers simulated how plastic pollution will spread through land, ocean, and atmosphere under different policy scenarios through 2060. Even with strong policy action, microplastics already in the environment will continue to circulate for centuries because existing plastic slowly breaks into smaller pieces. The study estimated the total marine plastic pool at 263 million tons, showing that preventing new pollution is critical but will not quickly solve the microplastic problem already in our ecosystems.
Plastics in the global environment assessed through material flow analysis, degradation and environmental transportation
Researchers conducted a global mass flow analysis of plastic emissions across all countries, tracking 8 polymer types across 10 sectors into 7 environmental compartments. The study estimated that 0.8 million tonnes of microplastics and 8.7 million tonnes of macroplastics entered the environment in 2017, with tire wear being the largest source of microplastic emissions. Modeling predicts that even with zero plastic production after 2022, approximately 2.15 gigatonnes of plastics would still accumulate in the environment by 2050 due to landfill leakage and degradation.
Future Projections of Global Plastic Pollution: Scenario Analyses and Policy Implications
This study used data from 128 countries to project future plastic pollution levels based on population growth, wealth, and technology. The researchers found that plastic pollution follows a curve where it rises with economic growth but could decline once countries reach a certain development level. The projections suggest that without policy changes, global plastic pollution and the resulting microplastic contamination will continue to increase significantly.
A mass budget and box model of global plastics cycling, degradation and dispersal in the land-ocean-atmosphere system.
Researchers developed a global mass budget and box model tracking plastic cycling across terrestrial, oceanic, and atmospheric reservoirs from 1950 to 2015, incorporating historical production data, fragmentation, and transport dynamics for macroplastics, large microplastics, and small microplastics. The model estimated that the deep ocean (82 Tg) and shelf sediments (116 Tg) represent major plastic reservoirs, and that even maximum feasible reduction scenarios would result in approximately 4-fold increases in atmospheric and aquatic microplastic exposure by 2050 due to legacy plastics already in circulation.
A mass budget and box model of global plastics cycling, degradation and dispersal in the land-ocean-atmosphere system
Researchers built a global computer model tracking how 8,300 million metric tons of plastic produced since 1950 cycles through land, ocean, and atmosphere as it fragments into microplastics over time. Their modeling shows that even eliminating all new plastic releases from 2025 onward would still leave small microplastics cycling through the environment for millennia, because of the enormous stockpile of plastic waste already accumulated on land.
Microplastic Pollution in the Environment
This review examines the ubiquitous presence of microplastics as emerging environmental pollutants across all major environmental compartments, synthesizing data on their sources, fates, and concentrations over time and space to characterize the scale of global contamination.
Microplastics Pollution
This review addresses the exponential surge in global plastic production since the 1950s and the resulting widespread environmental contamination, projecting that annual production will reach record levels by 2050 without intervention. The authors assess the threats to ecosystems, wildlife, and human health and evaluate the urgency of transitioning away from current plastic production and waste management systems.
Forecasting global plastic production and microplastic emission using advanced optimised discrete grey model
Researchers used advanced mathematical models to forecast future global plastic production and microplastic emissions. Their projections suggest that both production and emissions will continue rising significantly in the coming decades if current trends hold. The study provides policymakers with quantitative predictions that could help guide strategies for reducing plastic pollution.
Mapping of global plastic value chain and plastic losses to the environment: with a particular focus on marine environment
This report maps the global plastic value chain from production through use to waste management, estimating that millions of tonnes of plastic enter the ocean each year, with significant regional variation in management capacity. The analysis provides the economic and waste management context needed to understand why plastic pollution — and the resulting microplastic problem — continues to grow globally.
A local-to-global emissions inventory of macroplastic pollution.
This study developed a high-resolution global inventory of macroplastic pollution by distributing nationally reported waste management data down to sub-national and local scales, producing maps of plastic emission hotspots. The dataset is intended to support negotiations for a global plastics treaty by providing a data-driven baseline for identifying sources and prioritizing interventions.
Plastic dispersion and accumulation in the environment using a mass flow analysis approach
Researchers developed a material flow analysis model to quantify global plastic emissions and project their environmental accumulation through 2050 under business-as-usual, reduction, and zero-production scenarios. Results show that rubber microplastics from car tyres account for over 60% of global microplastic releases, accumulating primarily along roadsides and in subsurface waters, while packaging plastics from lower-middle-income countries dominate macroplastic inputs.
Driver, Trends and Fate of Plastics and Micro Plastics Occurrence in the Environment
This review examines the sources, trends, and environmental fate of plastics and microplastics, which have become a major global pollution problem due to massive production and poor waste management. Understanding how plastics move through the environment is essential for designing effective pollution controls.
Future scenarios of global plastic waste generation and disposal
Researchers projected global mismanaged plastic waste (plastic that ends up in the environment rather than being properly collected) through 2060, estimating it could triple from roughly 60–99 million tonnes in 2015 to 155–265 million tonnes annually — with African and Asian countries bearing a disproportionate share. Rivers were identified as the dominant pathway carrying 91% of land-based plastic waste to the ocean.
Plastic pollution in the marine environment
This review provides a comprehensive overview of plastic pollution in coastal and marine environments, covering everything from how plastics enter the ocean to their effects on marine life. Researchers compiled global data showing microplastic concentrations ranging widely across different water bodies and sediments, with marine organisms accumulating significant amounts. The study underscores that plastic pollution causes ecological damage through entanglement, ingestion toxicity, and the transport of invasive species.

Abundance of non-conservative microplastics in the upper ocean from 1957 to 2066
A combination of numerical modeling and transoceanic microplastic surveys from 1957 to 2015 was used to project Pacific Ocean microplastic abundance through 2066, showing ongoing accumulation particularly in the North Pacific as a result of removal processes (sinking, fragmentation) being slower than inputs. The study demonstrates that ocean microplastic levels will continue to rise under current emission trajectories.
