Eco-tariff
An eco-tariff, or environmental tariff, is a trade tax or barrier aimed at reducing pollution. A carbon tariff, or border carbon adjustment (BCA), is a type that taxes the carbon embedded in goods as they cross borders to prevent “carbon leakage” when some countries price carbon and others do not. Common targets include electricity from coal, steel, and fertilizer.
Proponents say eco-tariffs can push companies to cleaner production abroad, raise environmental standards, and harmonize rules between trading partners. They can also protect domestic industries from unfair competition by making pollution-costed imports more expensive.
Critics worry that tariffs can reduce global trade and may not address where pollution actually happens. Pollution often occurs within a country, so tariffs might shift pollution elsewhere. There are concerns about “green protectionism,” or using environmental goals to shield local industries. Trade rules from the WTO/GATT have limited how these tariffs can be used, and there have been disputes, such as past tensions between the U.S. and Canada over beverage containers.
History and current status: The United States proposed in 1991 the International Pollution Deterrence Act to create a pollution-control index of major trading partners. The 2001 Doha Development Round discussed environmental goods and the reduction of tariffs and barriers for items like catalytic converters and air filters. Today, California already has a carbon tariff for electricity; the European Union and the United Kingdom plan BCAs in the coming years, and several other nations are considering them.
Overall, eco-tariffs are debated: they could help reduce pollution and raise standards, but they may also limit trade and shift pollution elsewhere. The policy debate continues as ideas evolve.
