The same day ExxonMobil announced its ambition to achieve net zero greenhouse gas emissions by 2050, word spread that its mammoth plastics manufacturing complex near Corpus Christi, Texas, had begun production. 

“We are up and operating. We have been for a while,” Paul B. Fritsch, site manager for ExxonMobil’s joint venture with Saudi Basic Industries Corp, (SABIC), told the governing body of the Port of Corpus Christi at its Jan. 18 meeting.

The facility, known as an ethane steam cracker, will feed the production of nurdles – tiny pellets that serve as raw materials for plastic products. The plant’s state air permit allows it to send more than 3.5 million tons per year of carbon dioxide into the atmosphere.

The irony of promising net-zero emissions while firing up a greenhouse-gas polluter was not lost on some critics.


“Pledging to make your operations ‘net zero’ when your entire raison d’etre is to continue producing the fossil fuels destroying the livable world: this is like pledging to become more energy-efficient when your business is manufacturing electric chairs,” Genevieve Guenther, an author and activist who specializes in fossil-fuel industry disinformation, wrote on Twitter the day of ExxonMobil’s announcement.

The ExxonMobil-SABIC partnership, known as Gulf Coast Growth Ventures (GCGV), began construction of the plant in once-rural San Patricio County, on Texas’ Coastal Bend, in 2019. The GCGV facility is in addition to 31 new petrochemical projects along the Texas and Louisiana coasts that collectively will generate 50 million tons of greenhouse-gas pollution — the equivalent of 11 new coal-fired power plants, according to a report by the Environmental Integrity Project, a nonprofit research and advocacy organization. 

In a Jan. 20 press release, GCGV said its site started operations ahead of schedule.

It will produce “materials used in packaging, agricultural film, construction materials, clothing and automotive coolants.” In other words, mostly nurdles and antifreeze.

“We built this state-of-the-art chemical plant ahead of schedule and below budget, by leveraging our global projects expertise in execution planning and delivery, while keeping everyone safe and healthy,” Karen McKee, president of ExxonMobil Chemical Company, is quoted as saying.

Whether people in San Patricio County are kept “safe and healthy” remains to be seen.

Elida Castillo, the program director of Chispa Texas, an environmental advocacy group, lives five miles from the plant and has watched two tower flares burn for weeks. People who live closer have complained about noise and pollution from ground flares.

“The plant is not a good neighbor,” Castillo said. She worries about carcinogens, such as benzene, that are released into the air by the constant flaring. 

Neither ExxonMobil nor SABIC responded to questions about community members’ pollution concerns or complaints that GCGV hadn’t publicly announced the plant had begun operation. After the queries and a week after the port commission meeting, GCGV posted updates about the facility’s start-up activities to social media and sent an email to a community list.

Fritsch told port commissioners at the Jan. 18 meeting that the plant’s two major products — polyethylene and ethylene glycol — are used to make everyday items such as packaging and polyester clothing. “Likely everyone is wearing something with a polyester blend in it,” he said.

Two commissioners were solicitous of Fritsch. Catherine Tobin Hilliard asked for a private tour. Rajan Ahuja wanted a souvenir. Fritsch responded positively to both requests and said all the commissioners would be invited to GCGV’s grand opening celebration.

After Fritsch finished his presentation, the port’s chief executive officer, Sean Strawbridge, asked him to talk about ExxonMobil’s net-zero commitment.

“This, I would say, is a very greenhouse-gas friendly facility relative to previous generations of plants that were built, but it’s not net zero,” Fritsch said. “We need to think about how we do that. It is not something we can wait until 2045 to think about.”

Three people weighed in by video during a public-comment period at the beginning of the meeting. All were critical of the commission’s support of permitting proposed desalination projects they argue aren’t needed by residents and would benefit only industrial facilities like GCGV, which require large amounts of scarce freshwater in an arid region. 

One of the speakers, retired lawyer Errol Summerlin, questioned the port’s and ExxonMobil’s relationships with the National Renewable Energy Laboratory (NREL), part of the U.S. Department of Energy and another presenter at the day’s port commission meeting.

“NREL is engaged in the analysis of hydrogen production through electrolysis, which requires massive amounts of water — water that is not available in South Texas but for desalination projects,” Summerlin said. 

NREL is advising the port on decarbonization and energy transition efforts, with a focus on the federal infrastructure bill’s mandate to build regional hubs of hydrogen producers and consumers. Such an effort relies on freshwater supplies from the desalination projects under consideration by the port — and, as Summerlin pointed out, would also benefit GCGV’s backers. 

While hydrogen can be produced from renewables, today it is primarily produced from natural gas — a major source of greenhouse-gas emissions and a major product of ExxonMobil — and would require capturing those emissions using technology that is not yet commercially viable.

None of the commissioners responded to the speakers’ comments.
