## Question put to the AI subject

Which article of the BBNJ Agreement establishes the qualitative screening threshold that triggers an environmental impact assessment obligation for planned high-seas activities?

## AI subject's verbatim answer

Under Article 30 of the BBNJ Agreement, a planned activity in areas beyond national jurisdiction must be screened (Article 31) and, if warranted, undergo a full EIA

## Verbatim regulator text contradicting the answer

> Source: p_01 § Part IV EIA — Article 27 / screening threshold [general obligation establishing the 'minor or transitory' threshold]

_Source:_ [p_01_ACT_Part_IV_EIA___Article_27___screening_thr_text-bbnj-agreement.html](https://reglegbrief.com/substrate/INT/UNTC/BBNJ-HIGH-SEAS-BIODIVERSITY-AGREEMENT-2023/_raw_manual_substrate/p_01_ACT_Part_IV_EIA___Article_27___screening_thr_text-bbnj-agreement.html)
_Section anchor:_ Part IV EIA — Article 27 / screening threshold
