The "Atmospheric Brown Clouds (ABC) - Emission Inventory Manual" addresses the formation and impacts of regional air pollution plumes comprised of various pollutants. The manual, developed by UNEP and AIT, outlines methodologies for creating detailed emission inventories, emphasizing the significance of biomass burning and fossil fuel combustion in Asia, and provides tools and guidelines for count...

Low- and middle-income countries (LMICs) often lack the necessary tools, guidance, and capacity for compiling an emission inventory (EI) for air pollutants. A reliable EI is an important prerequisite for the identification of key emissions sources, as an input to modelling atmospheric transport and impacts of air pollutants, and the identification of appropriate mitigation policies. The publicly-a...

The EMEP/EEA air pollutant emission inventory guidebook provides guidance on estimating emissions from both anthropogenic and natural emission sources. It is designed to facilitate reporting of emission inventories by countries to the UNECE Convention on Long-range Transboundary Air Pollution and the EU National Emission Ceilings Directive. It is an essential tool allowing the compilation of compa...

Historical estimates for aerosol and precursor compounds are key data needed for Earth system, climate, atmospheric chemistry, and transport models, as well as for economic and energy models. Historical data are used both for general analysis and for model validation through comparisons with observations. The core CEDS project is funded by the US Department of Earth and Environmental System Modeli...

The GAPF-EI tool is a formulation of methods and assessment of good practice related to the compilation of emission inventories required for the development of effective policies and programmes to protect public health and the environment from the harmful effects of atmospheric pollution....

A set of land use database and a biogenic emission inventory system specific to biogenic emissions from natural sources that need to be accounted for in photochemical grid models....

VAPIS tool, one of the integral parts of the SIM-air family of tools, is an user friendly spreadsheet based tool, designed to quickly analyze emission trends for a single vehicular category for a single pollutant. This tool allows the user to start with the basic information on vehicular numbers, growth rates, age splits, kilometers traveled per day, average retirement age, and emission factors, a...

This working paper presents the description of the “Vehicular Air Pollution Information System” (VAPIS) tool. The VAPIS tool was developed to establish the emission trends and evaluate possible management scenarios for one vehicle category, using minimum inputs for the user. The tool can be replicated for multiple pollutants and multiple vehicle fleets, depending on the availability of the input d...

These revised guidelines assist Parties, through a common approach, in meeting their obligations under the Convention on Long-range Transboundary Air Pollution and its protocols. They support the evaluation of emission reduction strategies and facilitate the technical review of air pollutant emission inventories. They allow for the effective assessment of compliance with emission obligations under...

This guidance area addresses the issues of developing an accurate and reliable emissions inventory (EI) which can be used as input to dispersion models in order to estimate exposure of human populations and the environment. Information from EIs are also important for understanding air pollution sources to draw up control measures to mitigate industrial, transport, and residential emissions and ach...
