Abstract

The present paper gives an overview of the theory of green national accounting. Three purposes of green national accounting (measurement of welfare equivalent income, sustainable income, or net social profit) and two measures (Green NNP and wealth equivalent income) are considered. Under the assumption of no exogenous technological progress, Green NNP is shown to equal wealth equivalent income if there is a constant interest rate or if consumption is constant. It is established as a general result that sustainable income [les ] wealth equivalent income [les ] welfare equivalent income, while Green NNP [les ] welfare equivalent income under no exogenous technological progress and a constant utility discount rate. Green NNP is shown to measure gross social profit rather than net social profit.
