The internationally recognized Yemeni government on Feb. 24 issued an urgent plea to the international community following a Houthi attack on the Rubymar, a British-owned, Belize-flagged cargo ship carrying hazardous materials through the Red Sea six days earlier. The attack has raised fears of an imminent environmental disaster due to the potential leakage of ammonia fertilizer and oil from the abandoned and damaged vessel.

A group of environmental organizations filed a petition in the US Court of Appeals for the Fifth Circuit on Jan. 19 for review of the US Maritime Administration (MARAD) decision to license the Sea Port Oil Terminal (SPOT), to be built off the coast of Texas. The deepwater terminal is projected to expand production in the oil-rich Permian Basin. The activist groups said that expansion facilitated by the installation–to be largest offshore terminal in the US–threatens "disastrous levels of greenhouse gas pollution."

Mexico's President Andrés Manuel López Obrador on Feb. 9 called for a "pause" in relations with Spain, in a speech that explicitly invoked the legacy of colonialism going back to the Conquest. But the speech was clearly aimed principally at Spanish oil company Repsol, which had been favored during the presidential term of Felipe Calderón. Specifically, López Obrador questioned the granting of gas contracts in the Burgos Basin, in Mexico's northeast. He charged that Repsol operated the fields less productively than the state company Pemex had. "In the end, less gas was extracted than Pemex extracted" before the contracts, he charged.

Ecuador's trans-Andean Heavy Crude Pipeline (OCP) ruptured amid heavy rains Jan. 28, spilling oil into a sensitive area of Napo province and contaminating several rivers draining into the Amazon Basin, including the Napo, Piedra Fina, Quijos and, most seriously, the Coca. The contamination also penetrated Cayambe-Coca National Park. Pipeline operator OCP Ecuador didn't announce that it had stopped pumping through the stricken line until the following day, and at first denied that any waterways had been contaminated. This was repudiated in a statement from the Confederation of Amazonian Indigenous Nationalities of Ecuador (CONFENIAE), which cited reports from impacted Kichwa communities. 

Peru's authorities declared an environmental emergency on Jan. 20 after announcing that 21 beaches around the Lima area were contaminated by an oil spill at a refinery run by Spanish multinational Repsol, calling it the "worst ecological disaster" in the city's history. The Environmental Evaluation & Control Organism (OEFA) estimated some 6,000 barrels of crude had spilled—dramatically above the mere seven gallons that Repsol had initially reported to authorities when the disaster occurred five days earlier. Some 1,740,000 square meters of coastline and 1,1187,000 square meters of sea have been covered in sludge that has blackened beaches and killed marine life. Peru is demanding compensation from Repsol, accusing the company of trying to cover up the scale of the disaster and not having a contingency plan in place.

A prospective massive spill from an abandoned oil tanker in the Red Sea could lead to catastrophic public health effects in war-torn Yemen and neighboring countries unless urgent action is taken, according to a study led by researchers at the Stanford University School of Medicine. The FSO Safer is one of the world's largest tankers and is anchored five nautical miles (approximately nine kilometers) off the coast about 60 kilometers north of the port of Hodeidah, a key lifeline for aid supplies to much of Yemen's population. It holds 1.1 million barrels of oil—more than four times the amount spilled in 1989 by the Exxon Valdez. Abandoned since 2015 due to the conflict in Yemen, the dilapidated vessel is increasingly likely to leak oil due to deterioration of its hull, or to catch fire through the build-up of volatile gases or through a direct attack.

On the sixth day of a declared civil strike (paro) in Peru's Amazon rainforest, hundreds of indigenous protesters armed with spears seized oil installations Oct. 6, effectively shutting down the NorPeruano Pipeline. Station 5 on the pipeline, as well as oil exploitation blocs 192, 95 and 8, all in Loreto region, are under occupation. State company PetroPerú admitted that personnel have been evacuated from the pumping station, in Manseriche district, and that the seizure of the installation has "paralyzed the operations" of the pipeline. Awajún apu (traditional leader) James Pérez, speaking for the Indigenous Association for the Development & Conservation of the Bajo Yurimaguas, said the paro will continue until the central government responds to protesters' demands.

The Supreme Court of the United Kingdom on Feb. 12 allowed a case filed by 42,335 Nigerian claimants against Shell Oil and a Nigerian subsidiary to proceed in the UK courts. The claimants first sued Shell and its subsidiary in 2015 over leaks from pipelines in the Niger Delta that resulted in the destruction of farmland, the death of fish stocks, and poisoned drinking water. They argued that the oil spills occurred due to the negligence of the subsidiary company responsible for operating the pipelines. They charged that Shell's parent company owed them a "common law duty of care," since it exercised significant control over the operations of the Nigerian subsidiary.
