For a long period of time GNP has been used by economists as a measure of economic development. However, these days, so many objections have been raised for using GNP as an indicator of economic development by economists. They point out that GNP does not take into view the distribu­tion of income and wealth. Moreover, it is silent about the use of non-renewable natural resources such as mineral wealth.

Now a question arises as to what then should be measure of economic development and national welfare. The alternative measure should be such as may promote human welfare, equitable distribution of income and sustainable economic development. Such as measure is called Green GNP.
