BOGOTA, Colombia (AP) — The Iran war has exposed deep vulnerability in the global economy: dependence not just on oil, gas and coal for fuel, but on petrochemicals that underpin everything from food production to plastic packaging.As disruptions ripple through energy markets, the war is highlighting how fossil fuels are embedded far beyond transport and electricity. In the short-run, the widespread reliance will lead to higher prices for myriad products, while long-term the pollution that comes from petrochemicals will exacerbate climate change.A two-week cease fire announced late Tuesday is a hopeful sign that the war, and energy disruptions, will abate. But no matter when it finally ends, for many environmentalists to energy experts, ultimately the war is a stark sign that the status quo needs to change.AdvertisementAdvertisement“We cannot continue relying on fossil fuels neither for energy nor for material,” said Delphine Lévi Alvarès, global petrochemicals campaign manager at the Center for International Environmental Law. “We cannot continue relying on fossil fuels for absolutely everything around us.”Petrochemicals are expected to be a central topic of discussion in Santa Marta, a northern coastal city in Colombia, where governments will gather from April 24-29 for an international conference on transitioning away from fossil fuels. Experts say discussions will center on reducing demand because the sector is a major driver of future fossil fuel use. Indeed, environmentalists have long argued that fossil fuel companies, realizing that electric vehicles and green technologies like solar threaten their industries, see petrochemicals as a place for their products.Petrochemicals are primarily made from oil and gas and used to manufacture a wide range of everyday products, from plastic packaging and synthetic clothing to fertilizers, paints and medical equipment. Unlike fuels that are burned for energy, petrochemicals are turned into materials, making them a le …
