Sustainable development is the globally embraced paradigm for integrating environment and development policies. Agreement ends with attempts atoperationalizing the elusive notion of sustainability. A contentious debate among'environmentalists' and 'environmental economists' has brought about a confusingproliferation of indicators and policy advice on sustainable development. Greening the monetary national accounts could moderate the debate by generating conceptsand indicators which translate environmental concerns into the language of widely used economic variables.

The sustainedimplementation of sustainable development depends on it.
