UN votes to replace Mercator projection with Equal Earth

Summary

The UN General Assembly, in September 2026, called on member states to transition from the Mercator projection to the Equal Earth equal-area projection in educational and institutional maps by a vote of 164 to 1. Led by Togo and the African Union, this non-binding resolution does not ban Mercator or mandate changes to private software. The target scope includes textbooks, public maps, and media platforms.

Why it matters

Maps are fundamental mental models through which billions of people internalize the relative size, power, and importance of regions. A coordinated shift in the default projection could shape geographical literacy for generations. The near-unanimous vote demonstrates that map representation has evolved from a technical choice into a diplomatic and equity issue. The US emerged as the sole dissenting voice. This also highlights that a 450-year-old navigation tool remains dominant in visual culture despite having outgrown its original purpose in everyday contexts.

Highlights

• Resolution A/80/L.104 is non-binding. It is a 'recommendation' and imposes no obligations. It explicitly preserves the use of Mercator for maritime and aerial navigation.
• Equal Earth (2018, Šavrič/Patterson/Jenny) is a pseudo-cylindrical equal-area projection. It guarantees an area ratio of 1.0 at all latitudes while retaining curved meridians for visual familiarity.
• The six abstaining countries—Estonia, Georgia, Lithuania, Moldova, Serbia, and Ukraine—are all Eastern European or Black Sea coastal states. The article does not question this pattern.

Critical take

The article's framing, using phrases like 'silently misleading humanity' and 'breaking 450 years,' presents a well-understood mathematical trade-off as a form of deception. This is an editorial opinion, not a news-worthy finding. Mercator's distortion is a documented feature of its design, not a conspiracy. Furthermore, the article fails to present counter-arguments from the US or abstaining states, analyze what 'cognitive justice' means in practice, or provide a concrete timeline or implementation mechanism. It leaves the reader with a victory narrative rather than a concrete policy assessment.
