Key ports that have remained unaffected by Trump's One Big Beautiful Bill Act.

Many ports have utilized federal grants since 2008 to implement emission-reduction projects under the Diesel Emissions Reduction Act (DERA). However, the recent signing of President Trump's One Big Beautiful Bill Act has modified or rescinded funding for environmental programs, potentially affecting future DERA grants. While some ports report minimal impact due to existing grants or alternate funding sources, concerns remain regarding the long-term availability of funds for clean technology initiatives, as highlighted by various port officials.
