Welcome to the University of Cambridge Carbon Contributions Portal
Here you can calculate carbon emissions of your essential air travel for business and purchase the University-verified carbon contribution units.
Please only visit the portal having identified a flight as essential after following the University Guidelines for Sustainable Business Travel.
More information
Visit the Sustainable Business Travel Sharepoint pages, where you will find our FAQs around this Portal.
The units offered in the Carbon Contributions Portal are from the Gola REDD+ project, a project in the Gola Rainforest that works to reduce emissions from deforestation and forest degradation. Extensive research undertaken by Cambridge Centre for Carbon Credits (4C) has been vital to provide the University with the confidence to invest in the Gola Rainforest project.
For data protection, requests are anonymised after after two years (2 years since the last change to a request).
We retain the anonymised information about requests after that for long-term analysis.
Please keep your own records and documentation if you wish to record your details on purchases for longer than 2 years.
