The Plastics Pipeline: A Surge of New Production Is on the Way
A world awash in plastic will soon see even more, as a host of new petrochemical plants — their ethane feedstock supplied by the fracking boom — come online. Major oil companies, facing the prospect of reduced demand for their fuels, are ramping up their plastics output.

Companies like ExxonMobil, Shell, and Saudi Aramco are ramping up output of plastic — which is made from oil and gas, and their byproducts — to hedge against the possibility that a serious global response to climate change might reduce demand for their fuels, analysts say. Petrochemicals, the category that includes plastic, now account for 14 percent of oil use, and are expected to drive half of oil demand growth between now and 2050

Global emissions linked to plastic — now just under 900 million tons of carbon dioxide equivalent annually — could by 2030 reach 1.3 billion tons, as much as almost 300 coal-fired power plants, the Center for International Environmental Law found. If output grows as planned, plastic would use up between 10 and 13 percent of the carbon emissions allowable if warming is to stay below 1.5 degrees Celsius, the center reported.
Those emissions come from nearly every stage of plastic’s life. First, there is the energy-intensive nature of oil and gas extraction. Then, ethane cracking requires enormous amounts of power, with a concomitantly large greenhouse gas footprint. The Shell plant has a permit allowing it to emit as much carbon dioxide annually as 480,000 cars.
An estimated 12 percent of all plastic is incinerated, releasing more greenhouse gases, as well as dangerous toxins, including dioxins and heavy metals. Industry is promoting an expansion of incineration in waste-to-electricity plants, which it describes as a source of renewable energy. What’s more, new research suggests plastic in the environment releases greenhouse gases as it degrades — a potentially vast and uncontrollable source of emissions.
