Overview
- The KfW–Deloitte analysis presented at COP31 on Wednesday shows climate and environmental goods accounted for about 11 percent of world trade in 2025, with a traded value near $2.8 trillion.
- Trade in these climate goods grew faster than overall trade between 2017 and 2025, rising about 6.3 percent per year compared with 4.7 percent annual growth for global trade.
- Germany was the world’s second-largest exporter of emissions-reducing goods in 2025 with a 10 percent share behind China’s 26 percent and it was also the second-largest importer with an 8 percent share behind the United States at 15 percent.
- The fastest-growing product groups are climate-friendly mobility, renewable-energy technologies, and energy-efficient building components, and the study notes German strengths in high-value system solutions and wind-power innovation.
- Authors and German officials warn rising competition and concentrated supply chains pose risks to industry competitiveness and jobs, citing examples such as China's large share of battery and solar manufacturing and the effect Chinese solar imports had in lowering module prices for German installers.
