Pricing asymmetry (leakage exposure)
Observed exporter→importer trade arcs joined to World Bank carbon policies and in-force ETS coverage (EU27+ expanded). Spatial view colors arcs by binary instrument presence — an exposure indicator, not a carbon-leakage rate. Empty stays empty when upstream has no row.
No invented leakage %
DECARB does not publish leakage percentages, diversion elasticities, or firm relocation odds. Labels are binary: inventory has an instrument, or it does not. Classic exposure = unpriced exporter → priced importer (trade value on those arcs only).
