The oil used for shipping from Shenzhen to Long Beach is completely trivial compared to what the truck used getting it from Long Beach to Pasadena.
That's better than the situation in Vancouver, where containers from the port go by rail 1000 km/600 miles and over Rogers Pass (1300 m/4400 ft), to logistics centres near Calgary, and then back by truck to Vancouver.
oh okay then that consumption is totally fine. no worries here mate!
I'd love a napkin math calculation at this.
