New research indicates that ozone-depleting substances used as chemical feedstocks are leaking into the atmosphere at higher rates than previously recorded. These emissions, which were largely excluded from the original Montreal Protocol, could delay the full recovery of the ozone layer by up to 11 years. The study highlights a paradoxical trend where the production of these substances has increased by 163% since 2000, partly to create the very gases intended to replace banned CFCs. This gap in regulation underscores the need for updated emission reporting and stricter industrial oversight to ensure atmospheric recovery stays on track.
