Tools to calculate emissions
Introduction
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:
- general NPRI reporting tools (tools that could apply to a broad range of facilities)
- sector-specific tools and resources (below)
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. We have included sector-specific resources from the following external sources:
- Canadian Energy Partnership for Environmental Innovation (CEPEI)
- Canadian Fuels Association (CFA)
- United States Environmental Protection Agency (US EPA)
- Australian National Pollutant Inventory (Australia NPI)
You should exercise professional judgement, knowledge and care to determine and use the best information available to estimate your facility’s emissions.
Sector specific tools
You can use the filter options to search for your sector or to hide related guidance. Each record has tags displaying which sources of guidance are available.
