H. A. John Green has written:

'Consumer theory' -- subject(s): Consumers, Consumption (Economics)

"Green" economics are usually said to be driven by resource depletion, energy conservation, and pollution prevention. They are also driven by economics.

For example:

* It is cheaper to make things that use all the material you buy rather than discard it as waste or vent it as air pollution. * Big customers only "buy green" as a promotional activity

* Customers buy things that are eenergy efficient and last longer s they don't have a short replacement cycle. * Governments are now charging industry for high energy consumption and pollution emissions In short pollution and energy are said to be the drivers of green economics, but plain economic advantage is what sees it being adopted.
