This Excel-based template estimates facility-level emissions of greenhouse gases (GHGs) including methane, carbon dioxide, and nitrous oxide, as well as criteria air contaminants (CACs) including carbon monoxide, nitrogen oxides, non-methane VOCs, and sulphur dioxide.

This template provides a format for collecting appropriate data and estimates total facility-level emissions using default emission factors and equipment component counts as well as user-provided infrastructure and activity data for a given facility. The template also accepts direct measurement data, which, if available, will override emissions calculations and provide a more refined estimate.

Users seeking to estimate emissions at multiple facilities can fill out a unique SMART Plus Facility template for each facility.

If facility-specific emissions are aggregated across an entire country, the result would produce a national emissions inventory for the oil & gas sector consistent with an IPCC Tier 3 approach. If facility-specific emissions were calculated in this manner for only a representative subset of facilities, this process could yield IPCC Tier 2, or country-specific, emission factors.
