Exploring ITR score: Framing robust company-specific benchmarks and future company-level GHG emissions ranges
As Investors are looking to align their portfolios with the goals of the Paris Agreement, portfolio metrics like Implied Temperature Rise (ITR) are becoming increasingly popular. We describe a Task Force on Climate-Related Financial Disclosures-aligned ITR methodology and benchmark the results.
ESG Rating Revisions and Stock Returns
We study the six-month impact of ESG rating revisions on U.S. stocks. Decreases are followed by annualized negative returns of 3%, which are not driven by ESG-specific news; partly driven by sustainable index changes; and in line with long-term investors decreasing holdings after a rating decrease.
Divestment, information asymmetries, and inflated ESG ratings
We causally show that ESG ratings are inversely related to sustainable performance because firms face cost of capital incentives to inflate ratings given socially responsible investing under information asymmetries. Consequently, their promises of future sustainable performance do not realize, even up to 15 years in the future.
