NIIS has previously (2021–2022) addressed X-Road sustainability by conducting a study of the

environmental impact of X-Road and the possibilities of reducing it (including the Emissions Calculator).

In addition, there have been internal investigations for evaluating the sustainability of the X-Road

development process and integrating green software development principles into X-Road's current

development process (2023). Furthermore, a public X-Road Academy course Sustainability in Software

Development has been created.

Grounding on the abovementioned prior works, the planned aims (in 2022) of this study were to

investigate the following themes—focusing on the environmental sustainability:

X-Road software development process environmental impacts evaluation and improvement opportunities discovery (WP1).
X-Road environmental handprint evaluation (WP2).
X-Road carbon footprint measurement in actual operative environments comparing to the X-Road Emissions Calculator estimations (WP3).
