“Humanity has less than twelve years to cut global greenhouse emissions in half and just three decades to eliminate them almost entirely,” said Carol Muffet with CEIL. “The massive and rapidly growing emissions from plastic production and disposal undermine that goal and jeopardize global efforts to keep climate change below 1.5 degrees of warming.”
Comparing GHG estimates against global carbon budgets and emissions commitments, the report finds that if plastic production goes as planned, emissions will reach 1.34 gigatons per year by 2030. By 2050, the production and disposal of plastic may generate 56 gigatons of emissions, accounting for as much as 14 percent of the planet’s entire remaining carbon budget. The authors are quick to note their assumptions are conservative given the availability of data and the projection of plastic’s climate impacts are under a business-as-usual scenario. As such, realistic estimates suggest will actually be much higher.
“It has long been clear that plastic threatens the global environment and puts human health at risk. This report demonstrates that plastic, like the rest of the fossil economy, is putting the climate at risk as well. Because the drivers of the climate crisis and the plastic crisis are closely linked, so to are their solutions: humanity must end its reliance on fossil fuels and on fossil plastics that the planet can no longer afford,” said Muffet.
GHG emissions are emitted during each stage of the plastic lifecycle. Nearly every piece of plastic begins as a fossil fuel where extraction and transport can contribute significantly to GHG emissions directly through methane leaks and flaring, as well as fuel combustion and energy consumption. In the U.S. alone in 2015, emissions from fossil fuel extraction and transport attributed to plastic production was as high as 10.5 million metric tons of CO2 per year. The next phase, refining and manufacturing, is among the most GHG-intensive industries and are the fastest growing in terms of emissions. 05-17-19
