This paper investigates the spillover effects among global climate policy uncertainty (GCPU), global biodiversity attention (GBA) and the stock markets of the G7 and BRICS nations. In the static network, GBA's spillover effects towards stock markets are mild, with the US market experiencing the highest net spillover, while GCPU shows a large and widespread effect on various stock markets. In the dynamic network, the results show the spillovers from GBA towards the US stock market and from GCPU towards various stock markets both increasing during international conferences related to climate change and biodiversity.
