San Pedro Bay Ports’ Unprecedented Clean Air Record Will Continue to Improve Under Current State Regulations

A recent study conducted by the global environmental, climate, and sustainability experts at Ramboll consulting reviewed NOx emissions data and the current regulatory structure in place at the Ports of Los Angeles and Long Beach (San Pedro Bay Ports).  The analysis documents that dramatic reductions in total NOx emissions have been achieved over the last 20 years.  The study concludes that current and planned regulations result in even more dramatic emissions reductions by 2031 and 2037.

Ramboll conducted this study using 2006 and 2022 baselines for both on-site and off-site emissions included in the Ports’ emissions inventories. The study highlights each source category to reflect emissions expected from economic growth and increased equipment/source use by 2031 and 2037. It also reflects the emissions reductions expected from on-the-book regulations and natural fleet turnover. Where feasible, Ramboll used CARB assumptions to develop future projections.

The report identifies the sources of significant decreases that have already occurred as well as those that are expected to occur under the latest amendments in California’s regulatory system, such as ocean-going vessels (OGVs), heavy-duty trucks (HDVs), locomotives, commercial harbor craft (CHC), and cargo handling equipment (CHE).
