Increasing propellant gas emissions from pressurized metered-dose inhalers in obstructive lung diseases in France over 11 years
INTRODUCTION: ), contributing to climate change. The aim of this study was to estimate the carbon footprint of the propellant gases contained in all pressurized metered-dose inhalers prescribed in France, over an 11-year period. METHODS: equivalents based on their corresponding Global Warming Potential values. RESULTS: eq, representing a 38,7% increase, particularly pronounced since 2021. DISCUSSION: eq in 11 years, increasing annually. These findings highlight the substantial carbon footprint associated with current inhalers containing high Global Warming Potential propellant gases and underline the need to promote lower-impact therapeutic alternatives.
