Facilities in Ontario and across Canada need to report annual emissions of pollutants (greenhouse gas emissions, for example). Who needs to report, using what reporting scheme, and how to report can be tricky to navigate — especially if it’s your first time doing so and you lack knowledge on how to report properly to the National Pollutant Release Inventory (NPRI).

By following these simple steps, you can ensure your submission to the NPRI reporting consultants is accurate and that you meet all the legal requirements expected of you from the Government of Canada.

Reporting Online

In order to report pollutant releases online, make sure you fill out the comment boxes in order to give context to your report. You should also keep your information, most importantly your email address, current so NPRI reporting consultants can reach you if need be.

It’s also important to identify your public contact, the person whose name appears on the website, and the technical contact person. If you are reporting for multiple facilities, make sure you have co-ordinator information and to name consultants in the Contractor Contact box.

Avoiding Errors

For annual emission reporting services, try to avoid common errors like quantity errors. Report quantities in the proper measurements (for example, pounds vs. kilograms) and be on the lookout for decimal errors as well (for example, 500 pounds vs. 5.00 pounds). If you’re using pre-populated forms, ensure you update the quantities from the previous year.

For emission errors, volatile organic compounds (VOCs) in the first and second parts shouldn’t be greater than the total VOCs in the fourth part. Further., if more than one tonne of a Speciated VOC is reported in the fifth part, report it in the fourth part as well as individually in the fifth part. Finally, total Particulate Matter (PM)  should be ≥ PM10, which should be ≥ PM2.5.

For reporting errors, report only the release, disposal, and recycling amount, not the MPO amounts. Choose “No Significant Change or No Change” if change in quantities is less than 10%. Avoid double counting by not reporting disposals as on- and off-site. If a Part 1 substance meets an MPO recording threshold, report all releases, disposals, and transfers even if the released quantity is zero. GHG emissions consulting services can help if you have any trouble.

Complete and keep documentation, including:
1. Assumptions data
2. Emission factors
3. Emission measurement procedures
4. Internal calculations to support these measurements
5. Activity data
6. Sampling procedures
7. Equipment maintenance and calibration logs

Before submitting, verify the conversion rates are accurate, that mitigation activities were reviewed in your calculations, and compare this year’s estimates with last year’s estimates. Then report any significant changes that happened.
