Misalignment of climate investment and carbon mitigation potential in US venture capital markets

Abstract The US is not on track to meet the Paris Agreement goals. Climate technologies are a key determinant for adaptation and mitigation. We conduct a novel analysis of 1299 investments in the US, a leading location for financing and developing climate technologies. We evaluate venture capital and other financing vehicles for climate impact, drawing on additional datasets for mitigation potential and technological maturity. We used keyword categorization to match investments to associated technologies, climate sectors, technology maturity levels, and GHG mitigation potentials. Financing was found to be significantly skewed towards the transportation and electricity sectors, particularly electric transportation. This reflects a concerning concentration of capital that calls for diversification into other high-impact technologies. We also build a multiple linear regression to examine whether financing tracks with mitigation potential and maturity levels. The results reveal no significant relationships between carbon mitigation potential nor technological maturity, including their interactions with climate sectors and financing dollars. The model results indicate that these variables are poor predictors of funding allocation, suggesting that factors increasing climate impact do not drive investment decisions. We also examine the distribution of venture capital financing across company funding stages and the return on investment (ROI) for IPO-stage companies. We found a significant lack of funding at the middle stage of financing, which is a crucial growth juncture for climate projects. Our results indicate a concerning pattern for ROI, gesturing toward the importance of public funding to de-risk and accelerate technology development. Our analysis suggests that US climate financing is not distributed to meet global mitigation goals at both the investment and climate solution scale. In the context of a rapidly changing political and technological landscape, continued close monitoring of climate finance is crucial to identify gaps and improvements for maximizing the mitigation and adaptation impact of climate technology.
