When considering sustainability implications you need to think about how efficiently and environmentally friendly your outcome is.
This considers the development and running of your outcome. For example running a web server will have an environmental impact due to the electricity usage so low power or shared servers could be beneficial.
Questions that you should consider are:
- What are the environmental impacts of the outcome?
- How can the outcome be maintained in the long term?
- What are the most efficient resources that can be used to make the outcome?
