Decarbonising Respiratory Care: The Impact of a Low‐Carbon Salbutamol Pressurised Metered‐Dose Inhalers

Allergy, EarlyView.
Healthcare systems contribute up to 5% of global GHG emissions, with inhalers contributing a proportion of these. The carbon footprint of current salbutamol inhalers (pMDI with HFA‐134a propellant and DPI) and a planned salbutamol pMDI with low‐GWP propellant HFA‐152a was quantified across seven countries.

What's in the Bin? A Waste Audit of an Australian Tertiary Ear, Nose and Throat Outpatient Clinic

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Healthcare contributes 4.4% of global emissions. Climate change contributes to vector‐borne diseases, food insecurity and morbidity and mortality associated with extreme weather. Ear, nose and throat (ENT) outpatient clinics are particularly resource intensive, yet their environmental impact has not been quantified.

Assessing the environmental potential of carbon dioxide utilization: A graphical targeting approach [PDF]

, 2012
Carbon Capture and Utilization (CCU) has the potential to reduce both greenhouse gas emissions and fossil fuel use. However, the conversion of CO2 is intrinsically difficult due to its low energetic state.
