Any model of international trade that does not also model externalities is worse than useless. International trade accounts for 30 percent of CO2 emissions alone.
Maybe you should produce X and Z.
- topkai22 2y agoThat 30% number seems very wrong. The entire transportation sector is 12.5% of global emissions. International trade is more like 3% or less. https://ourworldindata.org/ghg-emissions-by-sector https://ourworldindata.org/ghg-emissions-by-sector
- trilbyglens 2y agoI think you could easily get into the 30% range if you factor in manufacturing that happens that otherwise would not without global trade.
- Jedd 2y agoIt seems like it would be extremely difficult to identify that breakdown. Not because it's difficult to identify emissions generated in order to produce those goods subsequently exported (it would be arduous to do so, but not infeasible), but because absent that particular manufacturing effort for those specific exports, what would that nation state instead be doing with those resources / what emissions would they be generating in the pursuit of domestic consumption needed to replace the income from those exports.
