This workbook contains cross-sector emission factors and unit conversions that can be used to estimate emissions from stationary combustion, purchased electricity, and mobile combustion.

The RAC tool calculates the HFC and PFC emissions from the manufacture, servicing, and/or disposal of RAC equipment. The tool offers three methods: A sales based approach for manufacturers and users; a life cycle stage approach for users; and a basic screening approach that is intended to help companies gauge whether or not their emissions merit the use of one of the other, more advanced methods.

The Aluminum tool, jointly developed by the International Aluminum Institute and the GHG Protocol, allows the CO2 and PFC emissions from primary aluminum production to be calculated. 

The Adipic acid tool allows the N2O emissions from adipic acid production to be estimated. It requires data on the amount of adipic acid produced. The tool also calculates any emissions reductions associated with the use of emissions control technologies.

The Ammonia tool requires data on the amounts of ammonia that a plant has produced. The tool allows emissions reductions associated with the use of by-product hydrogen to be calculated.

The CSI tool is for estimating GHG emissions from cement manufacture. This clinker based tool is suitable for when the amount of clinker consumed is known.

The CSI tool is for estimating GHG emissions from cement manufacture. This clinker based tool is suitable for when the amount of clinker consumed is known.

This tool is for estimating GHG emissions from cement manufacture. This tool requires data only on annual cement production. Emissions are calculated using clinker: cement ratios and CaCO3: raw meal ratios. This tool is based on the U.S. EPA’s ClimateWise program (1999).

The Iron and Steel tool provides two different methods for calculating CO2 emissions. One method requires data on the quantities of reducing agents and blast furnace additives used, as well as the quantities of the carbonate fluxes introduced into the furnace. The alternative method requires data on the amount of iron or steel produced, as well as of the carbonate fluxes. The emissions calculation from either method can be adjusted to account for the export of carbon-bearing byproducts.

The HCFC–22 tool provides two different methods for calculating HFC-23 emissions from HCFC-22 production. One requires data on the flow rate and composition of the HFC-23 exit streams. The other requires data on the amount of HCFC-22 that has been produced. Both allow the emissions reductions associated with the use of emissions control technologies to be calculated.

The Nitric acid tool allows the N2O emissions from nitric acid production to be estimated. It requires data on the amount of nitric acid produced. The tool also calculates any emissions reductions associated with the use of emissions control technologies. 

The Pulp and Paper tool offers a collection of tools that cover the emission sources typically associated with a pulp and paper plant. It is a joint product of the International Council of Forest and Paper Associations and the GHG Protocol.

The Semiconductor tool calculates the PFC emissions from semi-conductor wafer production. Required data include the quantities of gas that have been both consumed in wafer production and destroyed using abatement technologies, and the number of wafers produced by size.

The Wood Products tool offers a collection of tools that cover the emission sources typically associated with a Wood Products plant. 

The Lime tool allows the CO2 emissions from lime production to be calculated. It requires data on the quantities of the different lime types produced. 

This tool helps countries and cities assess progress toward national and subnational greenhouse gas reduction goals.
