The specific data needed to accurately calculate GHG emissions from these source categories are detailed in the
sections that follow.
1.1
Stationary Combustion
Stationary combustion emissions result from the combustion of fossil-based fuels (e.g. coal, natural gas, propane,
etc.) using equipment in a fixed location. Such pieces of equipment include boilers, heaters, incinerators, and
generators in offices, schools, and operations. Heaters within homes and operations equipment for industrial
businesses within the community are also stationary combustion sources and are included as part of the
Community-based GHG inventory.
The most accurate data to be collected for this source category is measured data. Meter readings from gauges
located at the specific pieces of equipment are the primary data source as they provide individual fuel usage. A
secondary data source would be gauges on tanks that supply fuel to the specific pieces of equipment and/or a
meter on a pipeline supplying fuel to an entire building and/or facility. These bulk fuel usage records provide
overall fuel usage, but may also include fuel loss to line leaks or other sources. The data required for assessing
stationary combustion source emissions consists of the following:
Fuel type
Annual fuel usage, by fuel type
Number of combustion units included, if grouped, by fuel type
Fuel heat content and/or carbon content, if measured, by fuel type
