WASHINGTON >> The Biden administration is awarding nearly $3 billion to boost climate-friendly equipment and infrastructure at ports across the country, including Baltimore, where a bridge collapse killed six construction workers in March and disrupted East Coast shipping routes for months.

President Joe Biden announced the federal funding Tuesday during a visit to the city’s main port, saying the money will improve and electrify port infrastructure at 55 sites nationwide while supporting an estimated 40,000 union jobs, reducing pollution and combating the climate crisis. The presidential visit, a week before Election Day, was intended to highlight efforts by Biden and Vice President Kamala Harris to promote clean energy while protecting and creating jobs.

“Ports are the linchpin to America’s supply chain,” Biden said in a speech at Dundalk Marine Terminal, near the site of the March 26 bridge collapse that closed commercial shipping traffic for nearly three months. A small blue and white sign near the site reminded passersby, “Project funded by President Joe Biden’s Inflation Reduction Act,” the 2022 law approved with only Democratic votes.

The new funding will help ports and communities across the country cut operating costs and keep consumer prices down, “while slashing carbon pollution and supporting an estimated 40,000 new, good-paying jobs to support clean energy manufacturing all across America,” Biden said.

“This is about environmental justice,” he added, citing studies that show higher childhood asthma, cancer and lung and heart disease in residents who live near U.S. ports.

Grants announced Tuesday include $147 million for the Maryland Port Administration to buy and install cargo-handling equipment and trucks to transition the port into a zero-greenhouse-gas-emission facility.

The Maryland port is among 55 ports across 27 states and territories that will receive nearly $3 billion through the Clean Ports Program administered by the Environmental Protection Agency. Ports receiving money include the Port Authority of New York and New Jersey, the Detroit-Wayne County Port Authority, the ports of Savannah and Brunswick, Georgia, as well as Philadelphia, Los Angeles and Oakland, California.

The grants are funded by Biden’s landmark climate law approved in 2022, the largest investment in clean energy in U.S. history.
