Abstract

There is a growing consensus that climate change poses a financial material risk to investors. In the face of escalating climate change risks, investors are seeking strategies to safeguard their portfolios. Building on a growing literature that combines textual analysis and dynamic hedging approach, we propose a method to construct portfolios of publicly traded assets that dynamically hedge climate change risk in the Norwegian stock market.
