RESUMO
While digitization and artificial intelligence represent the future of our specialty, future is also constrained by global warming and overstepping of planetary limits, threatening human health and the functioning of the healthcare system. The report by the Délégation ministérielle du numérique en santé and the French government's ecological planning of the healthcare system confirm the need to control the environmental impact of digital technology. Indeed, despite the promises of dematerialization, digital technology is a very material industry, generating greenhouse gas emissions, problematic consumption of water and mineral resources, and social impacts. The digital sector is impacting at every stage: (i) manufacture of equipment; (ii) use; and (iii) end-of-life of equipment, which, when recycled, can only be recycled to a very limited extent. This is a fast-growing sector, and the digitization of our specialty is part of its acceleration and its impact. Understanding the consequences of digitalization and artificial intelligence, and phenomena such as the rebound effect, is an essential prerequisite for the implementation of a sober, responsible, and sustainable digital pathology. The aim of this update is to help pathologists better understand the environmental impact of digital technology. As healthcare professionals, we have a responsibility to combine technological advances with an awareness of their impact, within a systemic vision of human health.
RESUMO
OBJECTIVES: The health sector contributes to climate disruption through greenhouse gas (GHG) emissions. It accounts for 8% to 10% of France's GHG emissions. Although the medical community has been alerted to the problem, more data are needed. This study aimed to determine the carbon footprint of a surgical pathology laboratory. METHODS: The study was conducted in the surgical pathology laboratory at Saint Vincent hospital (Lille) in 2021. It represented 17,242 patient cases corresponding to 54,124 paraffin blocks. The 17 staff members performed cytology, immunohistochemistry, and in situ hybridization. The study included all inputs, capital equipment, freight, travel, energy consumption, and waste. Carbon emission factors were based on the French Agence De l'Environnement et de la Maîtrise de l'Energie database. RESULTS: In 2021, the pathology laboratory's carbon footprint was 117 tons of CO2 equivalent (t CO2e), corresponding to 0.5% of Saint Vincent hospital's total emissions. The most significant emissions categories were inputs (60 t CO2e; 51%), freight associated with inputs (24 t CO2e; 20%), and travel (14 t CO2e; 12%). Waste and energy generated 10 t CO2e (9%) and 9 t CO2e (8%), respectively. CONCLUSIONS: The pathology laboratory's carbon footprint was equivalent to the yearly carbon impact of 11 French inhabitants. This footprint is dominated by inputs and associated freight. This suggests an urgent need to develop ecodesign and self-sufficiency in our routine practices.
