A negative externality (also called "external cost" or "external diseconomy") is an economic activity that imposes a negative effect on an unrelated third party, not ...
In law and economics, the Coase theorem (/ ˈ k oʊ s /) describes the economic efficiency of an economic allocation or outcome in the presence of externalities.The theorem is significant because, if true, the conclusion is that it is possible for private individuals to make choices that can solve the problem of market externalities.
Examples include environmentally related taxes, charges and subsidies, emissions trading and other tradeable permit systems, deposit-refund systems, environmental labeling laws, licenses, and economic property rights. For instance, the European Union Emission Trading Scheme is an example of a market-based instrument to reduce greenhouse gas ...

Thus, in many writings, even in those critical of the triple-bottom-line approach, the social becomes a congeries of miscellaneous considerations left ...
