Green software (definition)
From Green software
In  the definition for green software is introduced as "Computer software that can be developed and used efficiently and effectively with minimal or no impact to the environment". This definition has been derived from the definition of green IT as provided by Murugesan in Harnessing Green IT: Principles and Practices.
The demand for low environmental impact could be more strenuous in the definition, resulting in Computer software that is developed and used efficiently and effectively with minimal or no impact to the environment as an alternative definition.
The definition as introduced here does not include secondary effects on the environment a piece of software can cause. As an example of secondary effects: the operating system Windows Vista and the PC computer game Crysis caused many users to buy new computer hardware and abandon their former still fully functional equipment. In these cases the environmental impact can be traced back directly to the existence software.
