The Port of Los Angeles, the biggest in the U. S. , is buzzing with activity. Electric top-handlers move trailers on and off massive container ships. Some ships plug into electricity instead of burning diesel while in harbor. This shift is part of a broader effort to clean up the air around America's ports, which have long been hotspots for pollution.

People living near these ports have been breathing in harmful fumes for decades. The pollution comes from diesel-fueled cranes, trucks, and locomotives that move goods across the country. This pollution doesn't just affect port workers but also the 31 million Americans living nearby, often in Black, Latino, and low-income communities.

The Biden administration allocated $3 billion to reduce carbon pollution at 55 ports across more than two dozen states. This money is meant to fund cleaner equipment, vehicles, and infrastructure. However, some ports have already spent hundreds of millions on similar projects, and the demand for funding is much higher than what's available.

The Biden money aims to cut 3 million metric tons of carbon pollution. But will it be enough? Experts say it's a start, but more is needed. The Trump administration has been rolling back clean energy policies, which could disrupt these efforts. Some ports are already waiting for federal grant reviews, unsure of what's next.

Ports have been polluting for decades. They move everything from cars to building materials, emitting planet-warming carbon dioxide and toxic substances. While some ports have made progress, many still release significant amounts of pollutants. Independent groups confirm that emissions have slowed but not stopped.

Communities near ports are still at risk. Residents like Erandi Treviño from Houston blame port pollution for their health issues. Treviño uses several medications and an inhaler to manage symptoms she attributes to the Port of Houston. The port itself reports some reductions in pollutants, but certain emissions have increased due to more vessel activity.

The future of port pollution is uncertain. Ports are under pressure to automate and deal with labor issues. Switching to electric equipment is expensive and requires more space. Plus, ports need to upgrade their electrical services, which can cost millions. All this while imports continue to grow, and multiple agencies govern and regulate ports, making it hard to track progress.
