XDI can provide risk assessments at multiple levels of aggregation. Group-level aggregation is not a standard output but if required we are able to provide this level of detail.

Elevations come from from multiple national digital elevation model (DEM) datasets.

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).

Coverage rates vary per company and sector. If there is a specific request for coverage of companies or company groups, please share them with us and we can assess suitability or current coverage from our proprietary company database.

Climate Risk Engines were created in 2011. Developed by scientists, engineers and climate risk experts, this was the first time the cost of physical climate risk had been quantified in this way.Today, Climate Risk Engines are one of the most flexible, powerful and trusted sources of physical climate risk data in the world.

Data is regularly reviewed and generally updated in our system once these updates become available and have been evaluated. 
‍

Location-specific flood data is generally updated several times a year.

‍

Climate data is generally updated as 

(a) new Coupled Model Inter-comparison (CMIP) models are released, and 

(b) as downscaling is created by global research teams to the accuracy required for use by our Climate Risk Engines.

‍

All data sets got through quality assurance (QA) tests - sample QA reports are agreed at the time of contracting.

‍

XDI assesses 10 climate risk hazards, each with its own level of granularity, typically ranging from 5 to 50 metres.
