环境关税在过往未有实施,部分原因是因为当时的多边贸易制度,如世界贸易组织(WTO)并不认可环保关税的设立。而环保关税不被认可的原因,又是因为他们认为环保关税并非关贸总协定(GATT)所函盖的范围之内。因此,有相当的批评及对WTO及GATT作出改革的要求,希望纳入环保关税。
Additionally, many newly industrialized countries and underdeveloped countries saw the attempts to impose pollution controls on them as suspicious...
此外,许多新兴工业化国家和未发展国家认为,对他们强加污染控制的企图相当可疑:
...seeing it as a threat to their growth and fearing that developed countries would attempt to export their preferences for pollution control or to place 'environmental' tariffs on imports from countries with lower standards.

……认为这威胁到新兴工业化国家和未发展国家的成长,并担心发达国家会试图把他们的在污染控制方面的偏好强加于新兴工业化国家和未发展国家,又或对从污染控制标准较低的国家入口的产品实施环保关税。
