Travel Greenhouse Gas Emissions Calculator

*UPDATED FOR 2023* 
The calculator has now been updated with the latest GHG emission factors for 2023. If you are estimating travel emissions from a project for the year 2022 you can still access the original version here: Remote Consultations: Do they reduce Greenhouse Gas Emissions? Your Guide to Calculating the Answer (2022 version) | Sustainable Healthcare Networks Hub

This guide and carbon calculator have been developed by the Centre for Sustainable Healthcare in collaboration with PD Transformation and funded through Q by the Health Foundation and NHS England and NHS Improvement. It provides step-by-step guidance, along with an accompanying carbon footprint calculator, to support healthcare professionals in calculating the Greenhouse Gas (GHG) emission savings of (avoided) patient travel due to switching from in-person outpatient or GP appointments to remote consultations.

The guide has been developed for health professionals, quality improvement leads and estates, sustainability and practice managers at hospitals and GP practices. It can be used for a specific clinical pathway, a clinical department, or the whole organisation.

You can also use this tool for calculating staff, patient and visitor travel emissions more generally.
