Cloud Energy
and Emissions
Research Model

The C L E E R (Cloud Energy and Emissions Research) Model is a comprehensive user friendly open-access model for assessing the net energy and emissions implications of cloud services in different regions and at different levels of market adoption. The model aims to provide full transparency on calculations and input value assumptions so that its results can be replicated and its data and methods can be easily refined and improved by the research community.

We have used the CLEER Model to assess the technical potential of cloud-based business software for reducing energy use and CO2 emissions in the United States. More details on the model and the scenario are available in the report here and under the Model Description


The CLEER Model allows users to load the scenarios from the report or build a custom case study comparing present day with cloud.
