Clean Investment Monitor: US Q2 2026 Update
In the second quarter of 2026, clean energy and transportation investment in the United States totaled $75 billion, a 22% increase from Q1 2026 and a 4% jump from Q2 2025.
The Clean Investment Monitor tracks investments in the manufacture and deployment of clean energy and decarbonization technologies around the world.
The Clean Investment Monitor (CIM), created by Rhodium Group and MIT’s Center for Energy and Environmental Policy Research, tracks investments in the manufacture and deployment of clean energy and decarbonization technologies in every country around the world. Through our detailed, facility-level data and in-depth analysis, we provide insights into investment trends, the pace and scale of new clean technology manufacturing capacity, and the impact of policies on the evolving global clean energy landscape.
Over the past decade, public and private investments in clean energy and decarbonization technologies have grown significantly—accelerating manufacturing and the adoption of the technologies needed for clean electricity and transportation, building electrification, low-emission industrial production, and carbon management. As these decarbonization industries mature, new international trade and cross-border investment tensions between major economies have emerged. Governments are increasingly concerned about the security and resilience of clean energy supply chains and the need to counter the economic influence of their competitors through trade and overseas investment.
To navigate these challenges, decision-makers—both policymakers and investors—need to assess on-the-ground progress in the transition to a cleaner economy not only within their own borders, but globally. The Clean Investment Monitor provides real-time, methodologically consistent tracking of all public and private investments in the manufacture and deployment of a wide spectrum of decarbonization technologies worldwide.
The Clean Investment Monitor catalogs public and private investments in a wide range of decarbonization technologies and their input components. To create a historical baseline against which to assess recent clean investment developments, CIM includes all investments in our covered technologies since 2018. The data is updated on a quarterly basis.
Data Insight
In the second quarter of 2026, clean energy and transportation investment in the United States totaled $75 billion, a 22% increase from Q1 2026 and a 4% jump from Q2 2025.
Note
We dig into what’s been happening in Southeast Asia and India—regions that have absorbed the most solar manufacturing investment outside of the US, Europe, and China since 2018—and explore what these trends mean for broader diversification.
Note
In the first quarter of 2026, clean energy and transportation investment in the United States totaled $61 billion, a 3% decline from Q4 2025 and a 9% decline from Q1 2025.
Note
Global clean tech manufacturing investment has moderated after a decade of extraordinary growth. China and the US were the primary drivers of that rise and the subsequent pullback—though the nature of each country's decline differs significantly.
