Weirdly, those fancy international rules for 'quality' products are actually causing way more toxic air pollution in the countries making the goods.

Environmental Responses to Foreign Standards: Technical Barriers to Trade and the Geography of US Emissions
SSRN · 6358859
The Takeaway
When foreign nations impose strict technical standards on imports, domestic factories in the US often have to overhaul their production lines in ways that paradoxically lead to a significant spike in local sulfur and particulate emissions. It suggests that non-tariff trade rules designed for safety or compatibility can have unintended and localized environmental costs for the manufacturer.
From the abstract
We provide first causal evidence of the effect of foreign Technical Barriers to Trade (TBTs) on the local environment in a developed country. We combine data on TBT adoption by US' export destinations, bilateral US exports, and local industrial composition in a shift-share design to estimate the effect of exposure to foreign TBTs on regional pollution emissions in the US. We estimate that a 1 standard deviation (s.d.) increase in TBT treatment leads to 0.14, 0.05, and 0.13 s.d. increase in SO2 ,
