I am looking for resources on applicable and practical solutions for estimation and quantifying climate change risk from asset owners perspective (for example, a portfolio of equity, fixed income, and their derivatives). BIS published several papers/reports on this but they are largely related to banking sector.
In particular, I am interested in stress testing, scenario analysis, VaR, and other metrics that could be useful in estimating climate change risk.
As I was not able to find anything practical, I am willing to look at both asset class specific approaches as well as integrated cross asset methodologies. For example, pertinent to equities, we could potentially create a benchmark index that represents the "climate change" factor and look at the relationship between this factor and equity holdings in the portfolio.
