How avoided greenhouse gas emissions are measured

The Carrier CO2NSERVATION Meter estimates avoided greenhouse gas (GHG) emissions as a result of the installation of high-efficiency Carrier air conditioning, heating and refrigeration systems by customers around the world since 2000 and from UTC Climate, Controls & Security’s energy services business, NORESCO, since 2008. Buildings in the United States alone consume approximately 40 percent of all energy, and within buildings, heating, ventilating and air-conditioning systems account for approximately 40 percent of energy use. UTC Climate, Controls & Security has consistently invested in energy-efficient technologies and solutions to assist its customers in lowering that energy demand and the associated greenhouse gas emissions. To illustrate the avoided GHG emissions associated with energy-efficient products in use and to emphasize the impact of choosing more efficient products, Carrier developed the Carrier CO2NSERVATION Meter. The model compares the projected GHG emissions from select Carrier products to emissions from comparable baseline products, with the difference representing the estimated avoided emissions. The meter also incorporates energy savings as measured from energy service contracts. The model demonstrates the power of choosing high efficiency solutions.

Scope

The Carrier CO2NSERVATION Meter includes products from Carrier’s global portfolio. Only Carrier products are used in the model, including the comparison baseline products. The CO2SERVATION meter’s model is not based on all Carrier products, but only on those with accurate historical sales figures and equivalent baseline products. The products included in the meter represent the majority of the products in Carrier’s portfolio. We use 2000-2015 global sales data to estimate the total products in use. If sales data is not available dating back to 2000, we used the year with the most accurate figures as the starting year. GHG emissions from refrigerant leak rates are accounted for Carrier Commercial Refrigeration products only. The Carrier CO2NSERVATION Meter also includes estimated avoided GHG emissions that result from UTC Climate, Controls & Security’s energy services business, NORESCO.

For the majority of its products, Carrier chose to set baseline performance against industry and government standards. As these standards change, Carrier has adjusted the baseline performance to meet the established standard for that year. In this way, Carrier is continuously holding its product performance accountable to the highest energy efficiency standards. Measured against a constant 2000 baseline, the CO2 avoided would be approximately one-third more.

Third-Party Audit

In order to validate the CO2NSERVATION Meter’s methodology, assumptions and data, United Technologies Corporation hired TIAX LLC to conduct an audit of the model. TIAX LLC has expertise in HVAC and energy analysis and consults for both the private and public sectors. Examples of past projects include the California Clean Fuels Market Assessment and the Full Fuel Cycle Assessment: Well to Wheels Energy Inputs, Emissions and Water Impacts study, performed for the California Energy Commission and the Global Comparative Analysis of HFC and Alternative Technologies for Refrigeration, Air Conditioning, Foam, Solvent, Aerosol Propellant, and Fire Protection Applications, performed for the Alliance for Responsible Atmospheric Policy.
