Clinical trials to go green–A sustainable argument for decentralised digital clinical trials

Since climate warming poses a multifaceted threat, impacting the environment and economy [7,8], it is worth focusing on another important previously unexplored aspect of the digitisation of clinical trials: saving energy and CO2 emissions. [...]digitising clinical trials not only improves the clinical trial system, but is also less harmful for the environment. [...]a classical clinical trial needs about 10 times more CO2 and the full digitisation of a clinical trial saves 4,399 kg (90.1% reduction) of CO2. [...]other scenarios that involve different levels of decentralised and digitised practices (hybrid studies) offer a more realistic solution while still significantly reducing carbon emissions.
