Yes, we can present resultsets for the physical risk component of a TCFD report. We also produce a TCFD physical risk report.

We do not perform our own downscaling of global climate models. Currently, the majority of our models use data from the coordinated regional downscaling experiment (CORDEX). This simulation data uses CMIP5 projection data, which is a global projection based on the RCP scenarios, and downscales them to individual regions such as North America, Europe or Australia. 

Newer hazard models use CMIP6 data, which is the updated version of CMIP5 that uses shared socio-economic pathways (SSPs) as scenarios, which are similar to the RCPs for physical risk (though some additional SSPs exist). There currently is no version of CORDEX that downscales the CMIP6 data set.

RCP stands for Representative Concentration Pathway. Scenarios that include time series of emissons and concentrations of the full suite of greenhouse gases (GHGs) and aerosols and chemically active gases, as well as land use/land cover (Moss et al., 2008). The word representative signifies that each RCP provides only one of many possible scenarios that would lead to the specific radiative forcing characteristics. The term pathway emphasises that not only the long-term concentration levels are of interest, but also the trajectory taken over time to reach that outcome (Moss et al., 2010).

Tropical Cyclone/Hurricane winds are currently modelled using a relationship between their wind speeds and the sea surface temperature, with a degradation in wind speed as you move further inland due to the effects of land surfaces on Tropical Cyclone intensity.

The Technical Insurance Premium (TIP) is defined as the Annual Average Loss (AAL) per representative property for all hazard impacts combined. The TIP is based on the cost of damage to a property, expressed in current day dollars with no discounting or adjustments for other transaction costs.

Actual insurance premiums may not include the hazards we cover - for example Coastal Inundation and Soil Movement are excluded in some countries.

We do not currently include biodiversity in our analysis, however it is included in some capacity in our two-year roadmap for science and technology developments. If you wish to partner with XDI in developing metrics around biodiversity, please contact us.
