ICLEI has updated its popular CACP Software, re-released on April 16, 2009.

CACP 2009 is a new product that replaces the CACP Software, originally released in 2003. CACP 2009 has been updated to support emissions inventorying and climate action planning based on the principles and methods of the Local Government Operations Protocol (LGOP). To learn more about how to use this software, please refer to our FAQs.

CACP 2009 is a one-stop emissions management tool that calculates and tracks emissions and reductions of greenhouse gases (carbon dioxide, methane, nitrous oxide) and criteria air pollutants (NOx, SOx, carbon monoxide, volatile organic compounds, PM10, PM 2.5) associated with electricity, fuel use, and waste disposal. This tool can help you do the following:

• Create emissions inventories for the community as a whole or for the government's internal operations.
• Quantify the effect of existing and proposed emissions reduction measures.
• Predict future emissions levels.
• Set reduction targets and track progress towards meeting those goals.

Version 2.1 of CACP 2009 is Available Now!

Version 2.1 contains a number of updates to improve the functionality of the software. If you are a new user that has not previously installed CACP 2009, or have installed Version 2.0 but not yet entered data, click below for the latest version.

If you are a current user of CACP 2009 Version 2.0 (downloaded between April 16th and June 8th) there is a patch that will upgrade your existing installation to Version 2.1 specifications.

More About This Software

In 2001, ICLEI joined forces with the National Association of Clean Air Agencies (NACAA) and the U.S. Environmental Protection Agency (EPA) to build a software product that helps local governments create greenhouse gas inventories, quantify the benefits of reduction measures, and formulate local climate action plans. The result -- the original CACP Software -- has been helping local governments for five years develop climate action plans that harmonize strategies to reduce both greenhouse gas and air pollution emissions.

In 2008, ICLEI partnered with the California Air resources Board and the California Climate  Action Registry to develop LGOP. This emerging standard describes methods and data requirements that, in some cases, differed from those in the original CACP. ICLEI is releasing CACP 2009 to support LGOP.
