Plastic is a significant contributor to global warming and climate change. The production, disposal, and incineration of plastic emit vast amounts of greenhouse gases, including carbon dioxide and methane, at every stage of their life cycle. The extraction and transportation of fossil fuels, such as natural gas and crude oil, used to create plastics are carbon-intensive activities, releasing millions of metric tons of carbon dioxide equivalents (CO2e) annually. Plastic refining is also highly greenhouse-gas-intensive, with emissions from manufacturing ethylene, a key component of plastics, contributing significantly to global emissions. The incineration of plastics, particularly plastic packaging, further adds to the climate impact, with emissions equivalent to millions of passenger vehicles. While alternatives to plastic may exist, such as paper, they often require more raw materials and energy to produce, and can still release greenhouse gases during breakdown in landfills. As plastic production is projected to increase, addressing its environmental impact becomes crucial to mitigating climate change.

Plastic production and incineration could emit 2.8 gigatons of CO2 by 2050
Plastic is a major contributor to CO2 emissions. It generates heat-trapping gases at every stage of its lifecycle, from production to disposal. The production, disposal, and incineration of plastic are expected to increase dramatically, with production projected to double or even triple by 2050. This will have a significant impact on global CO2 emissions.
The plastic industry is on an exponential growth trajectory, and this trajectory has serious consequences for the environment. If the current growth trend continues, by 2030, emissions from plastic production and use could reach 1.34 gigatons per year, equivalent to the emissions of more than 295 new 500-megawatt coal-fired power plants. By 2050, the cumulative greenhouse gas emissions from plastic could reach over 56 gigatons, or 2.8 gigatons per year, accounting for 10-13% of the entire remaining carbon budget. This is almost 50 times the annual emissions of all the coal power plants in the US.
The manufacturing of plastic is both energy-intensive and emissions-intensive. Plastic refining is among the most greenhouse-gas-intensive industries in the manufacturing sector and is the fastest-growing. In 2015, emissions from manufacturing ethylene, the building block for polyethylene plastics, were 184.3 to 213 million metric tons of carbon dioxide equivalent, as much as 45 million passenger vehicles emit in a year. The extraction and transportation of fossil fuels, which are the feedstock for plastic production, are also carbon-intensive activities. The burning or incineration of plastic waste at the end of its life further contributes to emissions.
The impact of plastic on the environment is often overlooked, with more attention given to plastic waste littering cities and oceans. However, the production of plastic has a significant carbon footprint, and efforts must be made to reduce emissions at every stage of the plastic lifecycle. The "Hidden Costs" report suggests that a transition toward "zero waste" is the best path to reduce emissions, but this would require a significant cultural shift and a reevaluation of each step in a product's lifecycle.

Extraction and transportation of fossil fuels for plastic emit 12.5-13.5 million tons of CO2
Plastic is a form of fossil fuel, and it generates heat-trapping gases at every stage of its life cycle. The extraction and transportation of fossil fuels for plastic are carbon-intensive activities. The authors of the CIEL report estimated that 12.5 to 13.5 million metric tons of carbon dioxide equivalent are emitted per year while extracting and transporting natural gas to create feedstocks for plastics in the United States. This estimate includes the land disturbance that contributes to greenhouse gas emissions associated with extraction. For each mile of pipeline, a "right of way" zone of cleared land is required, and about 19.2 million acres have been cleared for oil and gas development in the United States alone. This land clearance results in a significant release of carbon dioxide into the atmosphere.
The impact of fossil fuel extraction and transportation for plastic production is not limited to the United States. Outside the US, where oil is the primary feedstock for plastic production, approximately 108 million metric tons of CO2e per year are attributable to plastic production, with extraction and refining as the major contributors. The manufacture of plastic is both energy-intensive and emissions-intensive, and it involves processes such as the cracking of alkanes into olefins and the polymerization and plasticization of olefins into plastic resins. These processes have significant environmental consequences, as seen with the 24 ethylene facilities in the US that produced 17.5 million metric tons of CO2e in 2015, equivalent to the emissions of 3.8 million passenger vehicles.
The expansion plans of the plastic and petrochemical industries further threaten to exacerbate the climate impacts of plastic. If the current trajectory of production, disposal, and incineration continues, global emissions from plastic could reach alarming levels. By 2030, plastic-related emissions may reach 1.34 gigatons per year, equivalent to the output of more than 295 five-hundred-megawatt coal plants. Looking ahead to 2050, the situation becomes even more dire, with plastic production and incineration potentially emitting 2.8 gigatons of CO2 annually. This amount of emissions is comparable to the output of 615 five-hundred-megawatt coal plants.
To address the climate impacts of plastic, urgent action is required. Reducing plastic production and use is crucial, and it is essential to keep fossil fuels in the ground. Policymakers, philanthropic funders, and global grassroots movements all have important roles to play in implementing effective solutions. Without decisive action, the cumulative greenhouse gas emissions from plastic by 2050 will far exceed the carbon budget necessary to limit global temperature rise to 1.5°C.

Plastic refining is a greenhouse-gas intensive process
The process of refining hydrocarbons, such as ethane and propane, into ethylene and propylene involves "steam cracking," which requires high temperatures of 900 degrees Celsius or more. This energy-intensive process breaks down the saturated hydrocarbon gases into their lighter, unsaturated monomers, the building blocks of plastic. The refining of these petrochemical products contributes to the significant greenhouse gas emissions associated with plastic production.
The extraction and transportation of fossil fuels, such as natural gas and oil, used as feedstocks for plastic production, are also carbon-intensive activities. The CIEL report estimates that in the United States, emissions from fossil fuel extraction and transport attributed to plastic production were 9.5-10.5 million metric tons of CO2 equivalents per year. Outside the US, where oil is the primary feedstock, emissions from extraction and refining for plastic production are even higher, at approximately 108 million metric tons of CO2e per year.
The impact of plastic refining on greenhouse gas emissions is further exacerbated by the quick turnaround to disposal. Plastic packaging, which accounts for 40% of plastic demand, is often designed for single-use and ends up in landfills, incineration, or recycling. Waste incineration has the most considerable climate impact among these options, with US emissions from plastic incineration in 2015 reaching 5.9 million metric tons of CO2e.
The life-cycle emissions of plastics, including production and disposal, contribute significantly to global emissions. Recycling and remanufacturing plastic can help mitigate these emissions, with potential carbon emissions savings of 30-80%. However, the continued expansion of the plastic industry and the predicted increase in plastic production threaten to make limiting global temperature rise more challenging.

Plastic packaging is often single-use, leading to a quick turnaround to disposal
The CIEL report estimates that in 2015, U.S. emissions from plastics incineration were 5.9 million metric tons of carbon dioxide equivalent. For plastic packaging, which accounts for 40% of plastic demand, global emissions from incineration reached 16 million metric tons of carbon dioxide equivalent in 2015. This estimate does not include the 32% of plastic packaging waste that goes unmanaged, open burning of plastic, or other practices that are challenging to quantify. Unmanaged plastic ends up in the environment, where it continues to have climate impacts as it degrades, releasing methane and other greenhouse gases as it breaks down.
The production of plastic packaging also contributes to carbon emissions. The process of converting fossil fuels into plastics emits significant carbon dioxide, with the production stage accounting for around 90% of the life-cycle emissions of plastics. In 2015, emissions from manufacturing ethylene, the building block for polyethylene plastics, were 184.3 to 213 million metric tons of carbon dioxide equivalent. This is projected to increase by 34% between 2015 and 2030.
To reduce the carbon emissions associated with plastic packaging, a transition towards "zero waste" is recommended. This involves responsible production, consumption, reuse, and recovery of materials without incineration or landfilling. Recycling and remanufacturing plastic can save at least 30% of the carbon emissions produced by original processing and manufacturing, with some estimates placing the savings at 70% to 80%. This could result in significant annual carbon emissions reductions.

Plastic waste left in the environment continues to have climate impacts as it degrades
Plastic waste is a significant contributor to climate change. The production, disposal, and incineration of plastic emit vast amounts of greenhouse gases, and these emissions are expected to increase as plastic production rises.
The impact of plastic waste on the climate does not end when plastic is thrown away. Plastic waste left in the environment continues to have climate impacts as it degrades. A study has shown that plastic at the ocean's surface continually releases methane and other greenhouse gases, and these emissions increase as the plastic breaks down further. Landfills, where a large proportion of single-use plastics end up, account for more than 15% of methane emissions. As the plastic waste in landfills degrades, it emits methane and contributes to climate change.
The degradation of plastic waste in the environment is accelerated by rising temperatures and moisture, which alter plastic characteristics, contributing to the generation of microplastics and the release of hazardous substances. This is particularly concerning in aquatic ecosystems, where plastic pollution already affects lakes, rivers, and seas. As the climate warms, the degradation of plastic waste is expected to increase, leading to more frequent failures of plastic products, reduced durability, and a shorter service life. This creates a cycle where more plastic waste is generated, exacerbating the problem of plastic pollution.
The impact of plastic waste degradation on the climate is not limited to direct greenhouse gas emissions. Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change. It affects the livelihoods, food production capabilities, and social well-being of millions of people. The problem of plastic pollution is interconnected with climate change, and addressing this issue requires collaboration across sectors, including industry, government, environmental organizations, and academia.
