Iowa Code section 455B.131, as amended by Senate File 485 in 2007, requires the department to include estimates of emissions of some greenhouse gases in its construction permitting and emissions inventory programs. This bill also instructs the department to create a voluntary greenhouse gas registry for purposes of tracking and crediting companies in Iowa that reduce their emissions of greenhouse gases or that provide increased energy efficiency.

Important information about which greenhouses gases need to be quantified, tools to help you complete the emissions estimates, and guidance on reporting requirements will be added to this web site as they are developed.

  If your facility falls into one of the five source categories listed below, please use the worksheet for your sector found under “Sector Specific Tools” on www.ghgprotocol.org/calculation-tools/all-tools. You will be required to register as a user of the Greenhouse Gas Protocol (GHP). GHP does not share registration information with any other parties.
• Cement Manufacturing (SIC 3241) use USA EPA version
• Lime Manufacturing (SIC 3274)
• Ammonia Production and Urea Application (SIC 2873)
• Nitric Acid Production (SIC 2873)
• Iron and Steel Production (SIC 3312)
If your facility uses soda ash, please use this spreadsheet:

The Iowa Department of Natural Resources (DNR) Air Quality Bureau has developed a new guidance document for estimating greenhouse gas emissions from selected stationary sources. The document contains information on data sources, emission factors, and estimation methods that are consistent with the Intergovernmental Panel on Climate Change Good Practice Guidance, the Inventory of U.S. Greenhouse Gas Emissions and Sinks, the California Climate Action Registry's General Reporting Protocol, and EPA guidance. This living document will be updated periodically to incorporate new emission factors and methods as they become available. The document suggests appropriate emission factors and estimation methods; use of specific emission factors is not mandated.

The Department has revised the Greenhouse Gas Emissions Estimation Guidance to remove Table 5.3 – Fugitive Refrigerant Loss. The table is used by the California Climate Action Registry's General Reporting Protocol to determine whether or not an air conditioning system is significant or de minimis for reporting. However, because the Iowa DNR currently does not have a de minimis reporting threshold, the table has been removed from the guidance as of 10/3/2007.

• Clearinghouse of Non-CO2 GHG Control Technologies - The California Air Resources Board (ARB) has posted a clearinghouse of non-CO2 GHG control technologies on its website. The technologies can be used to reduce emissions of non-CO2 greenhouse gases, such as methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and black carbon.

Starting on July 2, 2007, construction permit applications must include potential greenhouse gas emissions for the project. Applications received without this information will be considered incomplete and the permit(s) cannot be issued until the information has been received. Please note that the Linn County and Polk County air permitting programs are also subject to the same requirements. The following form (Form GHG) has been developed by the Department for the reporting of Greenhouse Gas Emissions for projects:

On July 5, 2007, Govenor Culver announced the signing of the State of Iowa onto The Climate Registry. The Climate Registry is a multi-state and tribe collaboration aimed at developing and managing a common greenhouse gas emissions reporting system with high integrity that is capable of supporting various greenhouse gas emission reporting and reduction policies for its member states and tribes and reporting entities.

This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building is also known as a sustainable or high performance building.
