N95 filtering facepiece respirators (FFRs) play a crucial role in protecting healthcare workers and the public from airborne pathogens.However, the production and disposal of these masks contribute significantly to carbon emissions.Addressing the carbon footprint of N95 respirators is vital for both environmental sustainability and public health.The majority of carbon emissions associated with N95 respirators occur during manufacturing, particularly the production of non-woven polypropylene and polyester used in their construction.This manufacturing phase accounts for a significant portion of the respirators' total emissions, alongside energy consumption and the extraction of crude oil for raw materials.Additionally, the incineration of N95 masks at the end of their life cycle contributes to roughly 25% of their total emissions.
