Global Biosphere Emissions and Interactions System (GLOBEIS) |
|
http://www.globeis.com 
The Global Biosphere Emissions and Interactions System (GLOBEIS) estimates emissions from natural (biogenic) sources and is designed for use in combination with photchemical modeling systems for ozone and particulate matter such as CAMx (the Comprehensive Air quality Model with extensions).

Global Emission Inventory Estimates |
|
http://www.geiacenter.org/reviews/start.html
The Global Emissions Inventory Activity (GEIA) was created in 1990 as an activity of the International Geosphere-Biosphere Program. Guidance and data on estimated emissions of various pollutants and source categories are provided on this site, including data on a global scale addressing both natural and anthropogenic sources.

International Petroleum
Industry Environmental Conservation Association
(IPIECA) Emission Inventory Model |
|
http://www.irr-neram.ca/CQ3Rome/Posters/cox.pdf
(PDF, 1 pg., 473 KB)
This document is the second volume in the International
Petroleum Industry Environmental Conservation
Association (IPIECA) Urban Air Quality Management
(UAQM) series and focuses on the role of emission
inventories in the process of developing sound
air quality management programs. The report discusses
the principles behind emission inventories and
describes the emission inventory model, or IPIECA
Toolkit, which has been developed by IPIECA and
consultants from Enstrat International Ltd. The
Toolkit allows policy makers and planners to build
an accurate and comprehensive emissions inventory
upon which to assess the cost-effectiveness of
alternative measures to reduce emissions. The
report also gives illustrations of where the Toolkit
has been used and the process for its integration
into air quality programs.

International Vehicle Emissions (IVE) Model |
|
http://www.issrc.org/ive/index.html
The International Vehicle Emissions (IVE) Model is a computer model designed to estimate emissions from motor vehicles in developing countries. The model includes local air pollutants, greenhouse gas emissions, and toxic pollutants.

EPA Emission Inventory Publications |
|
http://www.epa.gov/ttn/chief/publications.html
EPA's Emission Factor and Inventory Group has
developed numerous publications to assist individuals
and agencies in the preparation of U.S. emission
inventories. The documents include: inventory
planning for ozone, particulate matter (PM2.5),
and regional haze; a rule on consolidated emissions
reporting; emission inventory guidance for ozone,
particulate matter, and regional haze based on
U.S. regulations; a handbook for air toxics emission
inventory development for stationary sources;
and a guide for criteria pollutant inventory development
for point and area sources.

EPA Inventories &Emission Factors Software
|
|
http://www.epa.gov/ttn/chief/software/index.html
The site includes links to EPA inventories and
emission factors software and tools. Software
that is available on the site includes: Air ClearingHouse
For Inventories And Emission Factors (Air CHIEF),
which provides some of EPA's most widely used
and requested documents and most popular emission
estimation tools on CD-ROM; Factor Information
REtrieval (FIRE) Data System, a database containing
EPA's recommended emission estimation factors
for criteria and hazardous air pollutants; PM
Calculator, which calculates controlled emissions
for PM2.5 and PM10 for each point source; SPECIATE
3.2, a repository of total organic compound (TOC)
and particulate matter (PM) speciated profiles
for a variety of sources for use in source apportionment
studies; TANKS, which estimates volatile organic
compound (VOC) and hazardous air pollutant (HAP)
emissions from fixed- and floating-roof storage
tanks, and the Area Source Emissions Model (ASEM),
which calculates emissions estimates using default
methodologies established by the EPA.
