Port Of Los Angeles Achieves Lowest Emissions Per Container On Record In 2025

The Port of Los Angeles continued to make clean air gains in 2025, recording its lowest emissions per container on record, according to the Port’s newly released Inventory of Air Emissions. The findings mark another milestone in the Port’s clean air efforts, with emissions declining from the previous year and continuing a two-decade trend of significant reductions.

“The Port of Los Angeles continues to demonstrate that economic growth and environmental progress can go hand in hand,” said Los Angeles Mayor Karen Bass. “These results reflect years of investment, collaboration, and our shared commitment to building a stronger, more sustainable future for our Harbor communities while ensuring Los Angeles remains a competitive hub for global commerce.”

Since 2005, the Port has reduced diesel particulate matter emissions (DPM) by 90%, nitrogen oxides (NOx) by 72%, sulfur oxides (SOx) by 98%, and greenhouse gases (GHGs) by 16%, while container volumes have increased 37%.

The latest inventory also shows continued progress since 2017, when the Port of Los Angeles and neighboring Port of Long Beach updated their landmark Clean Air Action Plan to accelerate the transition toward zero-emissions operations. Emissions of DPM, NOx, SOx, and GHGs are down 15%, 38%, 28%, and 9% since then.
