Does this mean that those iPhone components will be manufactured in the US, then shipped overseas to be incorporated into new iPhones, which will then be shipped back to the US?
I understand that this makes sense, but at the same time, I wonder how many tons of CO₂ will be emitted because of this kind of "onshoring".
- lallysingh 3y agoFair enough. I wonder if this is a supply-chain security thing or a step towards eventually building the phones in the US.
- babypuncher 3y agoProbably a mix of both. China is a growing liability, and there is increasing political pressure to both diversify and onshore manufacturing. The growth in spending on US manufacturing over the last couple of years is kind of impressive.

- londons_explore 3y agoShipping of tiny electronic components around the globe doesn't have any substantial CO2 emissions, as long as they are shipped in bulk (and preferably by sea), simply because each component is so small/light. Shipping your bags of clothes when you go on holiday has a far bigger impact. Those are shipped by air (~50x the CO2), are far larger/heavier, and in a weeks time will be shipped back, perhaps unused.
- lnsru 3y agoNobody ships high value small expensive components by sea. It’s ok for reels of generic resistors. But not good for project specific parts.
- londons_explore 3y agoThey are normally shipped by sea to distributors.
- darksaints 3y agoAlmost all electronic components are shipped by sea. It is only finished goods that have a minuscule but real chance of being shipped by air.
- londons_explore 3y agoAnd even then, it is normally planned that finished goods are shipped by sea, and it is only when things fall behind schedule that air shipping is used as a way to get goods into the right place in time for release day.

While 30 years lifecycle FPGAs from Xilinx feel well in the container in open sea, project specific parts manufactured for specific client’s specific product with lifecycle of 2 years go by plane. Saving 1000$ and risking loosing business is not worth it.
- mynameisvlad 3y agoOne anecdote does not make a pattern. Just because your specific big corp does it does not mean all big corps do, let alone companies in general.

- coldpie 3y agoIt's a good question, and a very good thing to think about. It turns out shipping is actually surprisingly low on the list of contributors to carbon emissions. All global shipping together contributes about 1.7% of global emissions. That's in comparison to, say, industrial energy usage (24.2%) or passenger cars (11.9%) or residential buildings (10.9%) or animals raised for food (5.8%). Should carbon emissions of shipping be a factor in decisions like this? Unquestionably, yes. But at worst it's going to be a small tick in the negative column, and could actually come out ahead depending on other factors like local emissions regulations, etc. Source: https://ourworldindata.org/uploads/2020/09/Emissions-by-sector-%E2%80%93-pie-charts.png https://ourworldindata.org/uploads/2020/09/Emissions-by-sect...
- M4v3R 3y agoOne unrelated correction - you mentioned passenger cars are responsible for 11.9% of global emissions, but your source says this figure is for the whole road transport. Passenger cars AFAIK account for the third of that.
- coldpie 3y agoYes, good catch. I was getting that mixed up with the US EPA's stats[1]. FWIW they say passenger cars account for 58% of all transportation emissions within the US, more than all trucking, flights, and shipping combined. Again, within the US.

- kipchak 3y agoApparently shipping is slightly unusual as it produces a greater than average amount Sulfur Oxide due to bunker fuel's higher sulfur content though it is not considered a greenhouse gas such as in the graph. This is where headlines like "One cargo ship emits as much pollutants as 50 million cars" comes from, though the calculation is debatable.[1] For comparison gas or diesel is something like 10-15ppm Sulfur in the US now while historically bunker fuel is historically more like 3-5%, though it has been decreasing with regulations.
