Descrição: dc.descriptionGreen innovation provides a viable alternative for mitigating climate change. However, it is vulnerable to uncertainty shocks. This paper investigates the influence of climate policy uncertainty (CPU) on green innovation in 10 economies from 1997 to 2022 using time series methods (GVAR, VECM, and cointegrating relationships) along with four additional measures of uncertainty: economic, energy, financial, and geopolitical. Shock identification employs the dominant unit model of the GVAR to construct a structural shock, promoting a chain reaction that affects green innovation across economies. The results indicate that CPU shocks decrease green innovation across all economies, elucidating spillover effects. Additionally, CPU shocks increase economic policy uncertainty (EPU) and geopolitical risk (GPR). Decomposition of green innovation reveals that GPR is the principal factor, followed by EPU and CPU. The analysis shows heterogeneities: EPU is the main variable affecting green innovation in Japan and the U.S., while energy-related uncertainty (EUI) is significant in South Africa. The disaggregated analysis further breaks down green patents into four categories, with estimates indi cating that the most sensitive patents to CPU shocks are those related to climate change mitigation and environmental management. Additional checks, including time-varying bilateral trade and financial integration, reinforce these findings. Higher uncertainty undermines green innovation, compromising the goal of mitigating climate change.-
