Comparative advantage in environmental goods (index)
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.”  

Comparative advantage is a measure of the relative advantage or disadvantage a particular country has in a certain class of goods (in this case, environmental goods), and can be used to evaluate export potential in that class of goods. 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 value greater than one indicates a relative advantage in environmental goods, while a value of less than one indicates a relative disadvantage.
