Green economics is an approach to economics in which the economy is considered to be a component of, and dependent upon, the natural world within which it resides and of which is it considered a part. It takes the widest possible view of stakeholders of a transaction to include impacts to nature, non-human species, the planet, earth sciences, the biosphere.

A holistic approach to the subject is typical, so that economic ideas incorporate learning from other disciplines in a true transdisciplinary fashion, and important theories from feminist economics, post modernism, critical theory, ecology, international relations and peace, deep ecology, animal rights, social and environmental justice, anti-globalisation, eco efficiency, participation and localisation theories. Green Economics includes and builds on environmental economics and ecological economics, but is careful to include principles of social equity at the core of its concerns.
