A social-media influencer posts that a new waste-to-energy plant is “a toxic disaster”. A manufacturer calls the same technology “zero-emission”. A consultant searches the subject and finds both statements beside research papers, government notices and recycled news stories. Search engines can retrieve all of them, but they do not reliably distinguish expertise from noise.

That is the problem BIRI™ was built to address. A confident influencer with a large audience is not necessarily a reliable technical reference. Equally, a manufacturer may have genuine operating data alongside sales claims. Popularity, presentation and search position tell us little about the quality of the source.

BIRI™ maintains an environmental reference-domain dataset and a source-reliability rating system. Its purpose is to give researchers more context about where information originates, including sources that deserve further examination. It does not certify that every claim on a highly rated domain is correct.

Take the plant example. The influencer’s warning may point to a genuine emissions incident, or may simply repeat a rumour. The manufacturer’s claim may refer to one controlled test rather than routine operation. The researcher still needs permit records, monitoring results and independent evidence.

BIRI™ provides a way to assess the source before spending time on the claim. It is a BIRI™ function, not a Planetary.Blue consultancy service. Articles 11–14 explain how the reference collection was assembled, how domains were ranked for relevance and how human and virtual community members contribute their judgements.
