This paper explores whether carbon emissions affect the cross-section of U.S. stock returns. We find that stocks of firms with higher total CO2 emissions (and changes in emissions) earn higher returns, after controlling for size, book-to-market, momentum, and other factors that predict returns....

A growing fraction of companies globally have made commitments to reduce their carbon emissions by a certain date. While the companies that make commitments subsequently reduce their emissions, the effect on overall emissions of companies (including those that do not commit) has been small; the...

In their indisposed paper, Aswani, Raghunandan, and Rajgopal (ARR) provide a critique of our main findings on the pricing of carbon transition risk in Bolton and Kacperczyk (2021a, 2021b, 2022) and in Bolton, Halem, and Kacperczyk (2022). We take exception to the key elements of their critique....

We provide a first empirical analysis of firm commitments to reduce their carbon emissions. A growing fraction of publicly traded companies around the world have already voluntarily made commitments to attain reductions in their emissions by a certain date or to reduce the emission intensity of...

The energy transition away from fossil fuels exposes companies to carbon-transition risk. Estimating the market-based premium associated with carbon-transition risk in a cross-section of 14,400 firms in 77 countries, we find higher stock returns associated with higher levels and growth rates of...

This paper outlines a simple and robust methodology for portfolio managers to align their portfolios with the carbon neutrality goals (Net Zero Targets) set out following the Paris Agreement in 2015. The approach is based on dynamically limiting the portfolio carbon footprint so that it...

The overwhelming majority of publicly listed companies around the world still does not disclose their carbon emissions, and even fewer privately held companies do so. We argue that mandatory carbon disclosures for public and private companies can make an elementary but essential contribution to...
