To comply with the “Do No Significant Harm” (DNSH) principle, your company must assess and document that its activities do not negatively impact any of the six environmental objectives. This involves conducting environmental risk assessments, following best environmental practices, and ensuring that activities aligned with one objective (e.g., climate mitigation) do not harm others (e.g., biodiversity). Keep records of assessments and the measures taken to prevent significant harm as part of your reporting.
