NGFS IIASA Scenario Explorer
This web-based user interface provides intuitive visualisations and display of the transition scenarios time series data. This database also includes macro-economic data from the National Institute Global Econometric Model (NiGEM) as well as data on the impact of physical risks on GDP.
The scenario data is available for download as xlsx or csv files via the Transition Scenario Explorer, hosted by IIASA. Alternatively, the data can be accessed via a RestAPI or the open-source Python package pyam.
NGFS CA Climate Impact Explorer
This web-based user interface provides intuitive visualisations and display of the physical scenarios time series data. Extended sets of physical data can be found in the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) database. As a community-driven climate-impacts modelling initiative, ISIMIP offers a consistent framework for cross-sectoral, cross-scale modelling of the impacts of climate change.
The scenario data is available for download via the Climate Impact Explorer, hosted by Climate Analytics.
Code RepositoryThis web-based user interface provides a suite of tools and functions for analyzing and visualizing input data (i.e., assumptions/parametrization) and results (model output) of the scenarios. It enables simple analysis of timeseries data in the IAMC format, with an interface similar in feel & style to the widely used pandas –DataFrame-, but also advanced visualization and plotting functions with features for scripted validation & processing of scenario data and results.
Technical DocumentationThis document provides technical information on the two datasets constituting the NGFS reference scenarios. One dataset includes transition pathways and data on macro-economic impacts from physical risks, both of which available in the NGFS Scenario Explorer provided by IIASA. The other dataset covers the physical impact data collected by the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP). For each dataset, the most important technical details of the underlying academic work and a short user guide are provided.
NGFS Scenarios presentationThis ppt format document provides a high level description of the NGFS Scenarios. It includes a description of the main assumptions and highlights the main results regarding transition risks, physical risks and economic impacts.
NGFS Guide to Scenario AnalysisThis pdf format document provides an introduction to scenario analysis. It is not aligned on the second set of NGFS Scenarios hereinabove, but on the first set of NGFS scenarios published in June 2020.
SENSES ToolkitThis interactive interface offers a range of modules to learn about and explore climate change scenarios. There are modules adapted to newcomers as well as numerous expert level modules on various topics such as power-sector risks, the role of land for food production and climate protection, and investments opportunities and alignment.
TCFD’s work on scenario analysisThe Financial Stability Board (FSB) created the Task Force on Climate-related Financial Disclosures (TCFD) to improve and increase reporting of climate-related financial information. This task force has provided in 2020 a Technical Supplement regarding the use of scenario analysis in disclosure of climate-related risks and opportunities. Additionally, an online hub was set up with a wide range of tools and information related to scenario analysis.
UNEP FI’s work on scenario analysisThe United Nations Environmental Program Finance Initiative (UNEP FI) published in 2019 a comprehensive investor Guide to scenario-based methods for climate risk assessment, in response to the TCFD. UNEP FI’s TCFD Banking program ended its second phase in February 2021 with the publication of 3 new papers relating to scenario analysis, recommendations on integrated assessment models and the changing regulatory landscape.
