Data Verification

Every data point published on Angola Energia is cross-referenced against at least two independent sources where possible. Where a data point relies on a single source, this is noted. We distinguish clearly between confirmed figures and estimates.

Analysis Standards

Our analytical content adheres to the following principles:

• Transparency — assumptions and methodologies are stated explicitly
• Attribution — all claims are linked to verifiable sources
• Balance — we present multiple perspectives on contested issues
• Timeliness — content is reviewed and updated on a regular cycle
• Independence — we accept no payment from the companies or governments we cover in exchange for editorial content
