About The ICE Project

The healthcare sector is resource-intensive and contributes substantially to climate change and its negative health impacts. To build sustainable healthcare systems, randomised trials should assess environmental outcomes, such as climate impact, so that new interventions are evaluated for their effects on both patients and the planet.

The ICE Project brings together international experts to develop extensions to the SPIRIT 2025 and CONSORT 2025 guidelines, guiding the reporting of environmental outcomes in clinical trials.

These new guidelines, SPIRIT-ICE and CONSORT-ICE, will enable trialists to report measures such as carbon footprint, waste, and resource use alongside clinical outcomes. The SPIRIT-ICE and CONSORT-ICE extensions have been registered with the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) Network. The registrations are available here and here.

Our vision is that, in the near future, all major trials will integrate environmental outcomes with clinical ones, benefitting both current and future patients, the public, and the planet.
