Abstract: Cryptocurrency is a financial innovation that brings many potential benefits, yet it has been criticized for its negative environmental impacts. To fully reap the benefits from this financial innovation, it is important to understand its relationship with low- and high‑carbon-intensive financial assets. This paper investigates the time-varying and asymmetric spillovers among cryptocurrency, green and fossil fuel investments. Using a time-varying-parameter network connectedness model, we find that the spillovers among cryptocurrency, green and fossil fuel assets vary over time and that they are more pronounced during crisis periods. Our results also reveal asymmetric spillovers among these assets, where negative return spillovers are larger than positive return spillovers. In addition, we explore the influence of macroeconomic factors and uncertainty measures on the spillovers across cryptocurrency, green and fossil fuel investments. We conclude our paper by discussing the implications of our results for environmentally conscious policymakers and investors.
