Tools to calculate emissions

This toolbox is a collection of materials to help you if you have to submit information in response to Notices issued under s.46 of the Canadian Environmental Protection Act, 1999 (CEPA).

The toolbox consists of:

It does not contain a list of all reporting tools related to the NPRI. Other publicly available and site-specific tools/guidance may exist and may be useful in certain situations.

You should exercise professional judgement, knowledge and care to determine and use the best information available to estimate your facility’s emissions.
