A campaign has called on Prince Albert II of Monaco to cancel the annual Monaco Yacht Show, arguing that the event is incompatible with his public stance on climate change.
The petition, addressed directly to the Prince of Monaco, criticises the event over what campaigners describe as the environmental impact associated with superyachts and private aviation.
The campaign claims that the show attracts wealthy visitors who travel to Monaco by private jet and helicopter and says the event represents “luxury, excess, and extreme wealth”.
It also points to research by the Institute for Policy Studies, which it says recorded around 1,400 private jet flights into the region during the 2025 Monaco Yacht Show.
According to the campaign, those flights were responsible for 12,405 tonnes of CO₂e emissions, which it compares with the annual emissions of approximately 2,300 European citizens.
The figures are cited by the campaign as part of its argument for cancelling the event.
The petition also highlights Prince Albert’s long-standing involvement in environmental issues, referring to him as a prominent advocate for action on climate change.
It cites a description of him by The New York Times as an “eco-warrior” and argues that his environmental advocacy should extend to events held in Monaco.
The campaign’s organisers are also drawing comparisons with the European Business Aviation Convention & Exhibition (EBACE), a private aviation trade event which they say was cancelled following campaigning and criticism over its environmental impact.
The petition calls on Prince Albert to follow that example by cancelling the Monaco Yacht Show.
The organisers argues that the environmental consequences of private jets and superyachts should be considered alongside the wealth and luxury associated with the industries.
It also links the issue to wider concerns about climate change, including extreme heat, wildfires, drought and severe storms.
The petition says thousands of people in Europe have died as a result of extreme heat this summer and highlights Nepal as an example of a country whose population is particularly vulnerable to the consequences of climate change despite having contributed comparatively little to global emissions.
The campaign is sponsored by Inequality.org, which describes itself as an organisation focused on economic inequality.
It is asking members of the public to add their names to a petition addressed to Prince Albert calling for the Monaco Yacht Show to be cancelled.
