The European Superyacht Emissions Observatory

Every yacht leaves a wake. Some are measured in tonnes of CO₂.

Rolling 24h · EU waters

Nog geen gepubliceerd 24h-CO₂-cijfer

Nog onvoldoende dekking voor een betrouwbaar 24h-cijfer. De observatiepijplijn is vandaag gestart; dit cijfer verschijnt zodra voldoende jachten 24 aaneengesloten uren dekking hebben.

Dit is geen fout: de coverage-gate (≥70% dekking over een volledig 24-uursvenster) werkt zoals bedoeld en houdt onbetrouwbare cijfers tegen.

Share of the window covered by usable observations. One of three separate coverage metrics.

Context — not a methodology metric

The 21 superyachts this observatory tracks emitted an estimated 121.2–152.4 tonnes of CO₂ in the last 24 hours — annualised, roughly 44,238–55,626 tonnes a year, or about 1.7–2.1% of [PLACEHOLDER — annual saving vs. cumulative saving to 2030 not yet confirmed] the EU expects from its single-use plastics directive — the directive that gave you a cardboard straw. There is no comparable binding CO₂ regulation for superyachts.

Reference figure 2.6 Mt CO₂-eq. Single-use plastics scope only (2.6 Mt CO₂-eq). The wider 3.4 Mt figure also covers fishing gear and is not used here. Source: European Commission / European Parliament, Single-Use Plastics Directive impact estimates. Fleet total is annualised from a fixture window and is a placeholder until real coverage-adjusted data is available.

Three separate measurements. They are never merged into a single coverage figure.

How these numbers are made

Fuel burn is modelled from published engine specifications and observed speed, then converted to CO₂ with a fixed emission factor per fuel type. Nothing here is a measurement of fuel actually burned.
