Catastrophe models

  • CLIMADA: An open-source risk assessment model developed by ETH Zurich.[1][2] It uses probalistic modelling to estimate the expected economic damage as a measure of risk today. The model is well suited to provide an open and independent view on physical risk, in line with TCFD and underpins the Economics of Climate Adaptation (ECA) approach. As of today, it provides global coverage of major climate-related extreme-weather hazards (tropical cyclones, river flood, agro drought, and European winter storms) at high resolution (4km) for historic and some selected climate forcing scenarios (RCPs). Also see the introduction by European Environment Agency.
  • The Oasis Loss Modelling Framework ("LMF"): an open source catastrophe modeling platform. It developed by a nonprofit organization funded and owned by the Insurance Industry to promote open access to models and to promote transparency. Additionally, some firms within the insurance industry are currently working with the Association for Cooperative Operations Research and Development (ACORD) to develop an industry standard for collecting and sharing exposure data.
  • An open-source tools for the modelling and management of climate change risks is developed using CLIMADA by European Insurance and Occupational Pensions Authority (EIOPA)

Macroeconomic models

Table 1 lists the types of economic models that can be used to assess climate risks (NGFS, 2020[3]). For further guidance on selecting appropriate macroeconomic models, see the recommendations by the World Bank (page 26 of this report[4]).

Computable General Equilibrium  (CGE) IAMs Multi-sector and region equilibrium models  based on optimising behaviour assumptions G-CUBED, AIM, MIT-EPPA, GTAP, GEM-E3
Macro-econometric IAMs Multi-sector and region model similar to CGE but econometrically calibrated E3ME, Mercure et al., 2018[8]
Stock-flow consistent IAMs Highly aggregated model of climate change and the monetary economy that is stock-flow consistent Bovari et al., 2018[9]
Other climate-economy models Input-output (IO) models Model that tracks interdependencies between different sectors to more fully assess impacts Ju and Chen, 2010[10]

Econometric studies Studies assessing impact of physical risks on macroeconomic variables (e.g. GDP, labour  productivity) based on historical relationships Kahn et al., 2019[12]

Burke et al., 2015[13] Dell et al., 2012[14]

Natural catastrophe models and micro-empirical studies Spatially granular models and studies assessing bottom-up damages from physical risks SEAGLASS (e.g. Hsiang et al., 2017[15])
Modified standard macroeconomic models DSGE models Dynamic equilibrium models based on optimal decision rules of rational economic agents Golosov et al., 2014[16]

Large-scale econometric models Models with dynamic equations to represent demand and supply, coefficients based

NGFS Scenarios Portal

The NGFS Climate Scenarios Portal provides a comprehensive suite of data and tools to analyze transition risks, physical risks, and their broader economic and financial impacts. This was created for central banks and financial supervisors but has been reported useful for private sectors. This resource is widely recognized and used by key regulatory bodies, including the Basel Committee on Banking Supervision[20] and European Central Bank[21]. Figure 1 below shows an overview of the scenario analysis process using the NGFS portal.
