Green business, like environmental management, is not a single, simple sector. Rather it is made up of parts of different organisations with a broadly similar purpose – to invest in or provide resources for improving nature and the services we get from nature.
There is increasing focus within the worlds of finance and investment on sustainable investments, with a plethora of terms used for different aspects of this, such as responsible investment, greening finance, financing green, and impact investment. For a good introduction to these terms and the wider context of green business or finance, we recommend “Demystifying Green Finance” from the Valuing Nature Network.
