The CO2 Calculator will be freely available to use for 3 years starting November 2024. UAEG will take care of maintenance and updates during this time. One likely update will involve adding new countries to the dashboard. Currently, CO2 Calculator is only relevant for people interested in Belgium, Bulgaria, Germany, or Greece. The original focus on COMPAIR pilot countries limits the sustainability potential. More countries need to be added if the tool is to appeal to the wider user base. To this end, UAEG will add a form for requesting new countries. Technically, this work is not difficult to implement. New countries and languages can be added with relative ease as existing structures and processes allow for an efficient integration. The most challenging and labour intensive task would be finding the right emissions data.

The dashboard is built using proprietary technology, so the code is not available for reuse. The use of the platform itself, however, is more liberal, governed by the open-source CC-BY licence, which means people must attribute UAEG whenever CO2 Calculator results are used in blogs, coursework, social media, printed materials, reports, videos, and so on.
