Asset pricing and climate policy are analyzed in a global economy where consumption goods are produced by both a green and a carbon-intensive sector. We allow for endogenous growth and three types of damages from global warming. It is shown that, initially, the desire to diversify assets...

This research investigates the influence of methodological choices in portfolio sorts on the size of the carbon premium. By analyzing more than 100,000 methodological paths, we find that variations in the construction of brown-minus-green portfolios create substantial non-standard errors. From...

Combining policies to remove carbon dioxide (CO2) from the atmosphere with policies to reduce emissions could decrease CO2 concentrations faster than possible via natural processes. We model the optimal selection of a dynamic portfolio of abatement, research and development (R&D), and negative...

We study how the introduction of carbon taxes in a closed economy propagate in a credit portfolio and precisely describe how carbon taxes dynamics affect the firm value and credit risk measures such as probability of default, expected and unexpected losses.We adapt a stochastic multisectoral...

As Low Carbon portfolios have become increasingly mainstream, one finds that there are far too many seemingly equivalent products available to investors. As a result, accurately attributing the sources of carbon reduction become even more important. While there may not be one size that fits all...

The aim of the European Union's Emissions Trading Scheme is that by 2020, emissions from sectors covered by the EU ETS will be 21% lower than in 2005. In addition to large CO$_2$ emitting companies covered by the scheme, other participants have entered the market with a view to using emission...

As university endowments face pressure to divest stocks of companies contributing the most to climate change, much of the public discussion has focused on the looming math of the environmental impact of a carbon-based economy. As endowments decide whether or not to divest or implement screens,...

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...
