Ports continue march to zero-emissions

The US Ports of Los Angeles and Long Beach have reinforced their commitment to zero emissions, by signing an agreement with the South Coast Air Quality Management District. The agreement specifies concrete deadlines for moving to zero emissions.

Since around 2000, the ports here have been very concerned about cleaner air for the South Coast region of California. And there’s no question any more that people’s health in the region has suffered.

And the prolonged efforts since the Clean Air Program of a decade ago have made a significant improvement. The article states that the Clean Air Action Plan that preceded this agreement has already delivered measurable environmental gains, including 90% reductions in diesel particulate matter, 68% cuts in nitrogen oxides and 98% decreases in sulfur oxides from port-related sources since 2005.

The agreement addresses emissions from oceangoing vessels. One way is to use the Environmental Ship Index Incentive Programs. Another move is to zero emissions drayage operations. Some penalties will be introduced for violations.

Once implemented, the agreement will target emissions from cargo handling equipment, harbor craft, trucks, trains and ocean-going vessels across the ports complex.

Three cheers for organizations that keep their eye on environmental improvement despite the current negative talk.

The Hidden Bill for Climate Inaction: Costs Rising Across U.S. Counties

The Fall 2025 edition of Brookings Papers on Economic Activity contains this interesting paper which estimates the annual cost of climate events such as wildfires, air pollution, and warming weather. It’s no secret that climate change affects poorer members of society more. And we could guess that the West Coast, Gulf Coast, and Florida would see the largest effects.

But this analysis by US county really brings home the fact that climate change is costing every ne of us money even today.

One interesting observation is the huge jump in cost for mortality and for insurance. It makes the point that the risks are what is driving the cost. It means we have to think about probabilities and chance effects. Most people aren’t very good at estimating that. Or they can’t appreciate the meaning of a certain low-probability number; they assume it can’t happen to them!

The mortality costs come from the effects of wildfire smoke and from natural disasters. The extra heat alone doesn’t create much cost. The extra deaths from heat are roughly offset by a reduction in deaths from cold weather.

Insurance costs both direct (payouts due to disasters) and indirect (premium boosts or loss of coverage) are a big factor. We might not manage to afford the risk of climate change. This table illuminates the source of the costs.

A final note; local governments are going to increasingly bear the cost of climate events. They will need to invest in protections or raise money to pay for the disasters as they occur. You can bet that will be priced into local bond interest rates and increased local tax rates on property or sales.

The authors don’t claim to have covered all the costs. But the analysis down to the county level brings home to localities and individuals how they are being affected.

The Bottleneck in Green Fuel Supply for Shipping Industry

DNV, a major classification service for the maritime industry (it stands for Det Norske Veritas), is reporting that accounting for newbuilds that can burn alternate green(er) fuels, the bottleneck will be the supply of these fuels for maritime use.

It calls the phenomenon a “fuel transition tipping point”. It’s a strong demand signal for fuel producers. The graph shows the exponentially rising number of alternative fuel ships in the fleet, and adds the order book for the future. Methanol seems to be increasing quickly.

The infrastructure just isn’t there yet, and bunker operators and fuel producers need to step up their investments.

Green corridors are one approach that is gaining traction. In this scenario, several partners join forces with ports, fuel producers and bunker operators to make sure the infrastructure is there for fueling with green fuels on the route, usually point-to-point. Maersk has been a leader in this effort. Others are getting on board.
