The role of timely assessment of appropriate care in reducing greenhouse gas emissions in intensive care medicine

Background

Our era is characterized by the significant impact of anthropogenic activity, resulting in the paradox of short-term benefits, such as improved health, alongside potentially devastating long-term consequences for our species and the living world. Critical care, by attempting to preserve human lives through the massive mobilization of human, energy, and material resources, is a quintessential example of this paradox. It is therefore an ideal setting to explore the necessary compromise between care provided for the benefit of patients and the requirement to protect future ecological viability. The objective of our study was twofold: first, to evaluate whether conducting ethical reflections that lead to the early limitations, withdrawal, or non-initiation of certain invasive treatments to avoid disproportionate care would result in a reduction of greenhouse gas (GHG) emissions associated with critical care stays; and second, to quantify such a reduction.
