A “carbon footprint” (or: carbon inventory, carbon audit, greenhouse gas inventory) is an assessment of all greenhouse gases (GHGs) being emitted by a person or business within a specific time period, usually a year. The most commonly used standards for measuring carbon footprints are the World Resource Institute’s (WRI) Greenhouse Gas Protocol and the International Standards Organization (ISO) 14064 standard.


We create GHG Inventories (carbon footprints) to help individuals and organizations understand their emissions.

The GHG Protocol divides emissions into three scopes. Best practices require that organizations measure and work to decrease emissions from all Scope 1, Scope 2 and any significant Scope 3 emissions – as well as any other Scope 3 emissions where the data is easily available.

If you would like to receive a climate leader designation through Ostrom Climate (e.g., a carbon neutral company logo), then we need to calculate your footprint, or review one that you have prepared in order to ensure that it is complete and in line with our climate designation standards.

Individuals can calculate their emissions personal emissions from flights and driving here.
