Building on the success of the US Clean Investment Monitor (CIM), Rhodium Group and MIT’s Center for Energy and Environmental Policy Research (CEEPR) are now developing a Global Clean Investment Monitor (GCIM) to track investment in the manufacturing and deployment of clean energy technologies around the world. The first phase of GCIM’s development tracks investment in electric vehicles (EVs) and batteries, including total manufacturing investment and public subsidies supporting the production and uptake of EVs and batteries. In the coming year, GCIM will expand to cover a wide range of clean energy technologies.

This report analyzes first-of-a-kind comprehensive and rigorously sourced data on public subsidies for EVs and batteries in the world’s three largest EV markets: China, Europe, and the United States. It highlights trends in subsidies for EV and battery manufacturing and EV purchase across those regions in the period immediately preceding massive shifts in US policy, adopted as part of the recent reconciliation law. It also contextualizes EV and battery imports into the US and European Union by analyzing the trends in tariff rates over the period.
