How Warconomy uses this source

CREA analysis identifying the 'shadow'/'dark' tanker fleet carrying Russian oil. CREA is an independent research organisation; figures are estimates (authoritative research, not official government data) and vary by methodology and period. The cited cumulative share covers the period since the 5 December 2022 EU embargo/price cap as reported in the September 2023 publication — a dated snapshot, manually transcribed as a static fixture, not real-time, and recommended for refresh. Not legal or compliance advice.

Facts citing this source

  • CREA has identified a 'shadow'/'dark' tanker fleet that obscures Russian oil trade through practices such as ship-to-ship transfers and gaps in vessel-tracking signals; such estimates vary by methodology and are not directly comparable across sources.
