Environmental goods include both goods connected to environmental protection—such as goods related to pollution management and resource management—and adapted goods—which are goods that have been specifically modified to be more “environmentally friendly” or “cleaner.” A relatively high share of environmental goods imports indicates that a country purchases a significant share of environmental goods from other countries. A relatively high share of environmental goods exports indicates that a country produces and sells a significant share of environmental goods to other countries. A country’s environmental goods trade balance is the difference between its exports and imports of environmental goods.
