1. CarbonCount is an award-winning methodology used by Hannon Armstrong to provide our clients and investment partners the ability to evaluate the efficiency with which capital is employed to reduce greenhouse gases by estimating the carbon dioxide (“CO2”) emissions avoided annually per $1,000 of investment. Estimated carbon savings are calculated using the estimated kilowatt hours (“kWh”), gallons of fuel oil, million British thermal units (“MMBtus”) of natural gas, and gallons of water saved as appropriate, for each project. The energy savings are converted into an estimate of metric tons of CO2 equivalent emissions based upon the project’s location and the corresponding emissions factor data from the U.S. Government and International Energy Administration.

Hannon Armstrong periodically utilizes the CarbonCount and analytical methodology when marketing to our clients and investment partners engaged in the development of climate mitigation projects. We differentiate ourselves from our competitors by illustrating our many strengths and accomplishments in reducing carbon and financial risk through our investments, all of which are verified through the application of our CarbonCount methodology. Clients interested in partnering with Hannon Armstrong request and receive advisory assistance through the use of CarbonCount in prioritizing development and investment opportunities that will have the most significant impact on reducing carbon. In addition, the application of CarbonCount scoring across an asset portfolio results in verifiable reports for asset managers that depict the carbon impact of their portfolios.

2. WaterCount™ is a quantitative methodology used by Hannon Armstrong to provide our clients and investment partners the ability to evaluate investments in U.S.-based infrastructure and energy projects that calculates the expected water consumption reduction per $1,000 of investment. Estimated water savings are calculated as the sum of the direct annual estimated water savings from energy efficiency measures such as low flow water fixtures and the annual indirect water savings associated with the annual kWh generated and saved by our investments. The annual kWh of electricity generated and saved by our investments are multiplied by the amount of water withdrawn and not returned to local water systems based upon the project’s location and the existing grid electricity generating units in that region. Indirect water savings are estimated using data prepared by the U.S. Government’s Energy Information Administration and the Union of Concerned Scientists.

Hannon Armstrong periodically utilizes the WaterCount when marketing to our clients and investment partners engaged in the development of climate mitigation projects. We differentiate ourselves from our competitors by illustrating our many strengths and accomplishments in reducing financial risk, saving water and other natural resources through our investments, all of which are verified through WaterCount. Clients interested in partnering with Hannon Armstrong request and receive advisory assistance through the use of WaterCount in prioritizing development and investment opportunities that will have the most significant water savings potential. In addition, WaterCount scoring across an asset portfolio produces verifiable reports for asset managers that depict the water savings of their portfolios.
