Help shape how trials report environmental outcomes
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.
The ICE Project
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.
Interventions can then be weighed by their environmental impact, not by clinical effect alone.
For sustainability
Interventions can be weighed by their environmental impact, not clinical effect alone.
For researchers
A standardised, transparent guideline reduces heterogeneity and makes environmental reporting comparable.
For global health
Ultimately benefits current and future patients, the public, and the planet.
We invite healthcare professionals, trial investigators, methodologists, environmental scientists, patient and public representatives, funders, policymakers, and others with relevant expertise or interest to take part. Your input will help shape the checklists.
