Environmental finance has gained considerable attention globally as an emerging interdisciplinary research area.This study uses bibliometric analysis to systematically review major studies on environmental finance-relatedareas published since the 1970s. Through a bibliometric analysis of 892 environmental finance-related articlessourced from the Web of Science database, we identified the main research streams and illustrated the trendingresearch themes of environmental finance. We find that publications related to environmental finance haveincreased exponentially over the past decade. Current research streams include corporate and social re-sponsibility (CSR), climate negotiations, natural gas price volatility, national policy, and cost comparisons.Further analysis of the recent five years of literature shows that emerging research topics include climate finance,sustainable finance, firm value, climate risk, and green bonds. Finally, we conclude with a future research agendafor environmental finance.
