Asthma and COPD Inhalers: Essential Greenhouse Gas Impact Revealed Now

A new study reveals that greenhouse gas emissions from metered-dose inhalers (MDIs) used to treat asthma and chronic obstructive pulmonary disease (COPD) have risen over the past decade, with the majority of the environmental impact attributed to just three inhaler products. These inhalers rely on hydrofluoroalkane (HFA) propellants, potent greenhouse gases that contribute significantly to climate change. Despite advances in respiratory care, the increased use of these MDIs has led to a larger carbon footprint, highlighting the need for more sustainable treatment options.

The research underscores a growing environmental challenge within respiratory medicine, as MDIs remain a common delivery method for inhaled medications in the U.S. and globally. Alternatives such as dry powder inhalers (DPIs), which have a much lower carbon footprint, are available but have not fully replaced MDIs in clinical practice. This study brings attention to the urgent need for healthcare providers and patients to consider the environmental impact of inhaler choices alongside clinical effectiveness.

Why It Matters: The rising emissions from MDIs represent a tangible connection between healthcare practices and climate change, a pressing issue for the U.S. With respiratory diseases affecting millions, shifting to greener inhaler options could significantly reduce the medical sector’s carbon footprint. This aligns with broader public health goals to combat climate change while maintaining quality care.
