Except collaborated with Yale University to develop a customized online carbon calculator for the Yale Community Carbon Fund. The calculator allows anyone to estimate their carbon footprint and directly support projects that offset their impact.

The calculator is an intuitive and easy-to-use website for assessing greenhouse gas emissions linked to Yale events and operations. The website helps enhance users' knowledge about climate change and its impacts and guides them to offset them by supporting energy efficiency investments in local low-income communities.


Except conducts carbon assessments according to international standards such as the Greenhouse Gas Protocol, ISO 14064, and PAS 2050.

All projects use SiD, Except’s systems analysis approach to ensure relevance and comprehensiveness.

Your own calculator?

Except can deliver custom-built carbon calculators for your website and custom CO2 offset targets.
