Dear Chair Randolph and CARB Board Members, 

Ships, including harbor boats, are one of the worst air polluters
in California. To meet the requirements of both state law and
environmental justice, California must phase out diesel harbor
boats and instead invest in clean technologies and the jobs they
provide. 

Transitioning commercial harbor craft to 100% clean fleets is
feasible with existing technology. There are now over 300 operating
zero-emission ships powered by batteries worldwide, with another
194 on order. 

Our climate emergency demands bold  leadership. I urge you to
strengthen the Commercial Harbor Craft rule to: 

1. Require a zero-emissions transition for the majority of harbor
boats by 2035. This should include tugboats and barges, which are
excluded from the current rule 

2. Add language to allow the Board to revisit the rule as the
zero-emissions boat market evolves to ensure regulations achieves
maximum emission reductions 

3. Increase funding for zero-emissions boat pilots and retrofits to
spur innovation 

This is a critical time to protect the health of port-side
communities, Californian families, and our environment. 

Thank you for acting on this important issue.
