Greenhouse gas emissions from large facilities indicator: data sources and methods, chapter 5

5. Caveats and limitations

A facility is only required to report to the Greenhouse Gas Emissions Reporting Program if its emissions exceed the reporting threshold of 50 000 tonnes in carbon dioxide equivalent for a given year.

Comparisons among years may be made with the understanding that some facilities might not have been required to report in years for which they did not exceed the reporting threshold. Attention to consistency and comparability in the dataset is needed when comparing emissions from year to year.

Different facilities in a given type of industry may also use different methods for estimating emissions.

For a complete discussion of the caveats and limitations of the facility-reported greenhouse gas emissions data, refer to the Overview of Reported 2015 Emissions.
