What is an air emission inventory?
An emissions inventory is a database that lists, by source, the amount of air pollutants discharged into the atmosphere during a year or other time period.
What are essential elements of an emissions inventory?
A detailed emissions inventory (including fugitive and area sources) Description of current and projected(five years) plant operations. Detailed description of all emission sources and related control equipment. Current compliance status.
What is SLEIS?
• The State and Local Emissions Inventory System (SLEIS) is a web-based. application enabling the regulated community to manage and submit. point source emissions inventory data and related meta-data to state and local agencies.
How do you calculate emission inventory?
For Combustion Sources – If some form of applicable test data is not available, the emissions are calculated by multiplying the annual fuel throughput in the units shown on the emission inventory forms by an EPA factor for each contaminant. Percent sulfur and percent ash are used in calculations for some fuels.
How many types of emission inventory are there?
In general, there are four main types of emission sources: point, area, and on-road, and non-road mobile sources.
How do you calculate air emissions?
The general equation for emission estimation is: E = A x EF x (1-ER/100) where: E = emissions, A = activity rate, EF = emission factor, and ER = overall emission reduction efficiency, %.
How do you conduct GHG inventory?
GHG Inventory Development Resources

- Step 2: Collect Data and Quantify GHG Emissions.
- Step 3: Develop a GHG Inventory Management Plan.
- Step 4: Set a GHG Emission Reduction Target and Track and Report Progress.
How many types of emissions are there?
There are many types of radiation and radioactive emissions. The information we are providing discusses only the four most common types: alpha particles, beta particles, gamma rays, and x rays.
How do companies measure GHG emissions?
Currently, GHGs are measured using the Climate Footprint Calculator, the Global Reporting Initiative (GRI), and resources from the World Business Council for Sustainable Development and the World Resources Institute.
How do companies calculate their emissions?
Carbon footprints are usually measured in terms of an annual footprint that takes into account the impact of all the company’s key activities over the course of a calendar year, but it’s increasingly common for manufacturing companies to communicate their footprint on a per-product basis.
