ENVRI-FAIR has received funding from the EU to enhance the accessibility and interoperability of environmental research infrastructures (RIs). The project aims to develop common data standards and services across 13 RIs to make their data FAIR (Findable, Accessible, Interoperable, Reusable). This will improve scientists' efficiency and productivity by establishing harmonized policies and sustainable data management practices at each step of the data lifecycle. Implementation will be led by the RIs themselves using external services when needed, while ensuring solutions can be transferred between providers.
