The electric vehicle supply chain continued to account for the majority of this investment, but solar manufacturing investment is growing quickly, with a six-fold increase relative to Q3 of last year. Investment in clean energy production and industrial decarbonization grew by 31% year-on-year, to $19 billion in Q3. Within that, investment in emerging climate technologies like clean hydrogen, sustainable aviation fuels, and carbon management posted the fastest growth—up ten-fold relative to the same period last year. Retail purchases and installations of clean technologies grew by 22% year-on-year, to $31 billion in Q3, driven by 37% year-on-year growth in electric vehicle purchases by households and businesses.
