Greenhouse gas emissions associated with anaesthetic gases in Australia, 2002-2022: a retrospective descriptive analysis.

ABSTRACT:

Objectives

To assess changes in greenhouse gas emission rates associated with the use of anaesthetic gases (desflurane, sevoflurane, and isoflurane) in Australian health care during 2002-2022, overall and by state or territory and hospital type.

Study design

Retrospective descriptive analysis of IQVIA anaesthetic gases purchasing data.

Setting

All Australian public and private hospitals, 1 January 2002 - 31 December 2022.

Main outcome measures

Absolute carbon dioxide equivalent (CO₂e) emissions and CO₂e emissions rate per 100 000 population by gas and year, overall and by state/territory and hospital type (public or private).

Results

The overall emissions rate increased from 74 t CO₂e per 100 000 population in 2002 to 328
