About the Clean Investment Monitor

The Clean Investment Monitor (CIM) is a joint project of Rhodium Group and MIT’s Center for Energy and Environmental Policy Research (CEEPR). The CIM tracks public and private investments in climate technologies in the United States. Through this data and analysis, the CIM provides insights into investment trends, the effects of federal and state policies, and on-the-ground progress in the U.S. towards net-zero greenhouse gas emissions. 

The CIM provides a comprehensive, real-time, methodologically consistent and publicly-available source of information on investment in the manufacture and deployment of technologies that reduce GHG emissions in the U.S. The CIM covers dozens of different technologies and their input components across all sectors of the economy, including for clean electricity and transportation, building electrification, low-emission industrial production, and carbon management. To create a historical baseline against which to assess recent clean investment developments in the U.S., the CIM includes all investments in our covered technologies since 2018. This results in a database with roughly 20,000 individual facilities, 3 million zero emission vehicle (ZEV) registrations, 20 million heat pump sales, and 4.5 million distributed electricity generation or storage installations. 

Detailed data is available in our online database as well as through Rhodium Group and Breakthrough Energy’s ClimateDeck platform, including breakdowns of all investment trends at the state level. The CIM is updated on a quarterly basis.

Since 1977, the Center for Energy and Environmental Policy Research (CEEPR) has been a focal point for research on energy and environmental policy at MIT. CEEPR promotes rigorous, objective research for improved decision-making in government and the private sector, and secures the relevance of its work through close cooperation with industry partners from around the globe. Drawing on the unparalleled resources available at MIT, affiliated faculty and research staff as well as international research associates contribute to the empirical study of a wide range of policy issues related to energy supply, energy demand, and the environment. Research outputs include working papers, policy briefs, and contributions to larger interdisciplinary studies that leverage MIT’s unique research capabilities across the sciences and engineering. Additional dissemination channels include workshops, educational programs, and public outreach activities. CEEPR is jointly sponsored at MIT by the MIT Energy Initiative, the Department of Economics, and the Sloan School of Management. More information is available at ceepr.mit.edu.
