Ecological unequal exchange: quantifying emissions of toxic chemicals embodied in the global trade of chemicals, products, and waste
Tong, Kate; Li, Li; Breivik, Knut; Wania, Frank (Peer reviewed; Journal article, 2022)Ecologically unequal exchange arises if more developed economies ('core') shift the environmental burden of their consumption and capital accumulation to less developed economies ('periphery'/'semi-core'). Here we demonstrate ... -
