Fossil fuel companies driving plastic production

In 2018, at a Dubai resort next to the blue-green waters of the Persian Gulf, Amin Nasser, CEO of Saudi Aramco, stood before an audience of hundreds of petrochemical executives to set out his vision for the future of the world’s largest oil company. The goals he described weren’t primarily about energy. Instead he announced plans to pour $100 billion into expanding production of plastic and other petrochemicals.

Nasser predicted that with a growing global population wielding more purchasing power every year, petrochemicals—compounds derived from petroleum and other fossil fuels and of which plastics and their ingredients constitute as much as 80 percent—would drive nearly half of oil-demand growth by mid-century. About 98 percent of virgin plastics are made from fossil fuels. In sectors that include packaging, cars and construction, he said, “the tremendous growth in chemicals demand provides us with a fantastic window of opportunity.”

In the years since Nasser’s 2018 speech, Saudi Aramco, owned mainly by the government of Saudi Arabia, has acquired a majority stake in the country’s petrochemical conglomerate SABIC. Together the companies have bought into huge Chinese plastic projects and built petrochemical plants from South Korea to the Texas coast. Aramco aims to turn more than a third of its crude into petrochemicals by the 2030s—a near tripling in 15 years.

Although the industry has framed its plans to pivot to plastic as a response to consumer demand for a material central to modern life, another factor is clearly at play: As the looming dangers of climate change are pushing the world away from fossil fuels, the industry is betting on plastic to protect its profitability. Ramping up plastic and petrochemical output, according to Nasser, will “provide a reliable destination for Saudi Aramco’s future oil production.” As one industry analyst observed of the company’s strategy, “the big picture imperative is to avoid being forced to leave barrels in the ground as demand for transportation fuels declines.”

Even ExxonMobil has acknowledged that electric vehicles’ widespread adoption will probably reduce cars’ need for oil. In one market forecast, the company, already the world’s largest producer of single-use plastics, assured investors that its plans to increase petrochemical production by 80 percent by 2050 will help the industry to pump and sell even more oil at mid-century than it does today.

But there is growing public awareness that all the plastic made for packaging and goods from the absurd to the essential comes at steep costs: the health impacts of the chemicals it contains, the emissions from its production, the mountains of waste that have built up as it is discarded, and the microplastics found everywhere from the most remote corners of the planet to our brains. Some governments have begun enacting legislation, such as bans on certain single-use items, but efforts to deliver more sweeping change hit a wall with the collapse in August of contentious negotiations on a global plastic-pollution treaty. More than 70 nations had pushed for limits on the amount of plastic produced to reduce the flow of waste into the environment. The industry has lobbied heavily against such caps, arguing that improved waste management and recycling are the solution, even though only a small percentage of plastic is currently recycled and many types cannot be recycled by conventional means.

Companies “know they can’t hold their finger in the dike” of an energy transition, says Judith Enck, a former U.S. Environmental Protection Agency official and president of Beyond Plastics, an advocacy group based at Bennington College. “They have to find a gigantic new market, and they have landed on plastic.”

Plastic production has been rising steadily since the end of World War II, when companies poured resources into finding and promoting peacetime uses for a material whose military applications—from nylon parachutes to polyethylene insulation for radar sets—had proved invaluable. Consumers snapped up the flood of new goods and disposable packaging, and the annual output of plastic has climbed from two million metric tons in 1950 to more than 500 million today. A cumulative 8.3 billion metric tons had been produced by 2015, according to a landmark study that was the first to quantify the total amount of plastic created. According to Roland Geyer, an industrial ecologist at the University of California, Santa Barbara, who co-authored the study, the total has since risen past 10 billion metric tons. About three quarters of all that plastic has become waste, Geyer’s team reported: 9 percent was recycled, 12 percent was incinerated, and 79 percent ended up in landfills or the environment. If current trends continue, 1.1 billion metric tons of plastic will be made annually by 2050—and the cumulative total will be enough, Geyer says, to cover the U.S. in an ankle-deep layer.

Today half of all plastic goes into single-use items, which are often tossed away almost as soon as they’re acquired. A million plastic bottles are purchased each minute, according to the United Nations’ environment agency, and five trillion plastic bags are used every year. In 2016 Americans alone used more than 560 billion plastic utensils and other disposable food-service items.

Plastic, of course, is not just in throwaway packaging. It is a defining, inescapable part of modern life, widely used in construction, clothing, electronic goods and cars. It plays a key role in health care as a component in gloves, syringes, tubing and IV bags, not to mention artificial joints, limbs and hearts. It is also not just one material: there are thousands of types and subtypes, each with its own combination of chemicals that yields desired properties—varying degrees of hard or soft, rigid or flexible, opaque or transparent. One analysis found that 16,000 different chemicals are used in making plastics, including additives such as stabilizers, plasticizers, dyes and flame retardants. More than 4,000 of those substances pose health or environmental dangers, and safety information was lacking for another 10,000, the researchers estimate.

By design, plastic does not readily decompose. Instead it fragments into increasingly minuscule pieces—reaching down to the nanoscale—that have been found just about everywhere scientists have looked. They suffuse the air we breathe, the water we drink and the food we eat. They’ve been detected in blood, semen, breast milk, bone marrow and placentas. Scientists are only beginning to explore what this omnipresence means for the health of humans and the environment, but the signs are worrying. One recent study found microplastics in tissue from human kidneys, livers and brains, and a study of 12 dementia patients’ brains showed greater accumulations than those of people without the disease. Other research found the tiny particles in the neck-artery plaque of nearly 60 percent of patients tested; three years later the rates of heart attacks, strokes and death were 4.5 times higher among people whose samples contained microplastics.

Plastic also exacerbates the climate crisis. The production and disposal of single-use plastics alone creates more greenhouse gases than does the U.K., says the Minderoo Foundation, an Australian research group. That footprint includes the extraction of the oil and gas used to make plastic, the energy-intensive processes for synthesizing it, and emissions from waste that is ultimately burned.
