Global investments in clean tech manufacturing drop

Global investments in clean technology manufacturing dropped 42% to $155 billion in 2025 after peaking in 2023, with significant declines in China and the US. China's decline reflects market oversupply from state support, while the US decline is more concerning as it occurs before planned investments materialize. Washington's rollback of clean energy incentives and trade restrictions on Chinese imports, along with policy unpredictability, have deterred Chinese companies from US manufacturing investments.
