“Costa Rica Bans All Aerosol Spray Cans to Protect the Ozone Layer?”
The claim that Costa Rica uniquely prohibits the sale of all aerosol spray cans to protect the ozone layer — with stricter penalties than most countries — is false. Costa Rica phased out CFC-based aerosol propellants as part of its ratification of the Montreal Protocol, exactly like nearly 200 other nations worldwide.
Costa Rica's environmental reputation
Costa Rica is genuinely one of the world's most environmentally progressive nations — it has set aside nearly 25% of its land as national parks and reserves, consistently ranks highly on international environmental performance indices, and has ambitious carbon-neutrality goals.
Real action on ozone-depleting chemicals
The country did take real action on ozone-depleting chemicals: it ratified the Vienna Convention and the Montreal Protocol (Ley 7223) in 1991, and enacted Executive Decree No. 35676-S-H-MAG-MINAET to regulate and phase out ozone-depleting substances (ODS). CFCs — the class of chemicals historically used as aerosol propellants — were fully banned from import by 2010. This is identical to the obligations taken on by all 197 signatories of the Montreal Protocol, which is the first universally ratified treaty in UN history.
No ban on modern aerosol cans
Modern aerosol cans do not use CFCs; they use hydrocarbon propellants (butane, propane) or compressed CO₂. These products are sold freely throughout Costa Rica. No legislation, regulation, or decree creates a general ban on aerosol spray cans, nor are Costa Rica's penalties uniquely strict compared to other nations.
Where the story gets it wrong
People often conflate Costa Rica's phase-out of CFC-based aerosol propellants — an obligation shared by all ~197 Montreal Protocol signatories — with a unique national ban on all aerosol spray cans. In reality, aerosol cans using modern, non-ODS propellants are freely available throughout Costa Rica, and the claim of 'stricter penalties than most countries' has no evidentiary basis.
No such blanket national ban on aerosol spray cans exists. Costa Rica ratified the Montreal Protocol via Ley 7223 (1991), committing to phase out ozone-depleting substances (ODS) including CFCs, which were historically used as aerosol propellants. Executive Decree No. 35676-S-H-MAG-MINAET establishes mandatory controls and phase-out schedules for ODS in compliance with Costa Rica's Montreal Protocol obligations. CFC imports were eliminated by 2010. Aerosol cans using non-ODS propellants (e.g., butane, propane, CO₂) remain freely sold and are not prohibited.
