Basics

Title may need some work?
ANYWAYS:
This page goes over what the economy would look like post Decentralization of most aspects of production, post Fossil Fuels, and in a perspective wherein all affected areas are "developed" (at least to the extent where they can no longer be exploited for cheap labor and low enviromental protections/government regulation)
This would vastly change current impacts of Economies of Scale , Logistical Costs , and the issue of "Can it be profitable compared to fossil fuels/fossil fuel derived products"
Also given that all areas in the relevant scope/scale/perspective would be "developed" outsourcing labor for lower labor costs would also no longer be a factor (at least to a major extent, as Cost of Living still would vary due to climate etc
Need to dig for studies on this/aspects of it, also get outside opinions (especially economists, and engineers (in relevant fields such as chemical engineering etc) )

On the Potential Factor of a Carbon Tax

Even in an era before total a phase-out of Fossil Fuels, a Carbon Tax essentially "levels the playing feild" for low carbon, and carbon neutral/negative business models

Due to products having a much longer lifespan, the cost of Moldmaking, and other aspects of manufacture of single items/goods, This model of business argued mainly by the "Current Economy of Scale" would be unprofitable in nearly all circumstances
However Agriculture, Chemical Processes, and some forms of Power Production, may still benefit

Due to shipping becoming more expensive due to a post-"bunker fueled shipping container barge" based world transit system, international shipping may cost more
- Need data on what this will look like
However growing transit infastructure may make certain forms more economical
Also products having a longer lifespan will reduce the constant demand/consumption making giant shipments of identical products obsolete in most cases
Perhaps low cost, and high speed may become more of a factor than volume
