The Integrated Assessment Modeling Consortium has coordinated several processes to collect quantitative integrated assessment scenarios from the research community. Most notably, this includes scenarios assessed in three Reports of the Intergovernmental Panel on Climate Change (IPCC), the Fifth Assessment Report (AR5) of Working Group III, the Special Report on Global Warming of 1.5°C (SR15), and the Sixth Assessment Report (AR6) of Working Group III. A set of online databases documents the assessed scenarios and makes them available to the scientific community, policy analysts, decision makers and the public at large for easy reuse. These databases are hosted by the International Institute for Applied Systems Analysis (IIASA) on behalf of the IAMC which has been formalized in a cooperation agreement between the Working Group III TSU of the IPCC, IAMC and IIASA.
In addition, jointly with the Climate Modeling and Impacts, Adaptation and Vulnerabilities research communities, the IAMC has coordinated the development of a set of new climate change scenarios. These scenarios are part of a new framework that the three research communities have adopted to facilitate the integrated analysis of future climate impacts, vulnerabilities, adaptation, and mitigation – the so-called “SSP-RCP framework”. The underlying datasets that are provided in two online databases hosted by IIASA on behalf of the IAMC.
Finally, the section showcases datasets elaborated by other IAMC Members, in the effort of providing a thorough platform on existing data on IAMs.
With the same aim, a Zenodo IAMC community for associated data sets has also been established. It makes finding IAMC data sets easy and is curated by the IIASA ECE program. Adding your data set to the Zenodo IAMC is easy and can be done during upload of new data or added to existing data sets. When editing your data set, under ‘Communities’ simply search for ‘IAMC’ and select it. The IIASA Zenodo admin is then notified and can accept your request.
This new opportunity to effectively share data and other material with other fellow researchers, complements the existing IAMC GitHub organization that for some time allows to share and jointly develop source code of models and tools related to IAM research. GitHub and Zenodo can also be used together to make releases of source code citable and via the Zenodo IAMC community easily findable by other IAM researchers.
EDGARv8.0 is the second product of the new EDGAR Community GHG emissions database, which is the outcome of an agreement between JRC and IEA to work more closely to gather and provide consistent harmonised CO2 emissions from fossil fuel combustion. EDGARv8.0 provides estimates for emissions of the three main greenhouse […]
This Scenario Explorer holds emissions scenario data that was submitted to the European Scientific Advisory Board on Climate Change (ESABCC) in response to this Call for Contributions of emissions scenario data that can support its work in advising the EU on policy measures, climate targets and greenhouse gas budgets. In June 2023 the ESABCC […]
As part of the IPCC’s Sixth Assessment Report (AR6), authors from Working Group III on Mitigation of Climate Change undertook a comprehensive exercise to collect and assess quantitative, model-based scenarios related to the mitigation of climate change. Building on previous assessments, such as those undertaken for the Fifth Assessment Report […]
International Transport Energy Modeling, or iTEM, is an open group of people and organizations interested in the role of energy in the world’s transport system. Their shared goal is to better understand the methods and data that are employed to study this system—especially, model with international or global scope—and through dialogue […]
This Scenario Explorer hosts the results from the Integrated Solutions for Water Energy and Land project. Integrated Solutions for Water Energy and Land project (ISWEL) seeks to develop tools and capacities to support the sustainable management of water, energy and land, through the development of a truly nexus approach. The […]
The National Determined Contributions (NDCs) provide important indications regarding the future GHG emissions and related policies, in relation to the international energy market, technological, economic, trade and financial context. This key information on the development trajectories of major economies is essential for EU policy development as it will determine the […]
The Network of Central Banks and Supervisors for Greening the Financial System (NGFS) partnered with an expert group of climate scientists and economists to design a set of hypothetical scenarios. They provide a common reference point for understanding how climate change (physical risk) and climate policy and technology trends (transition […]
I2AM PARIS is an open-access, open-source (GitHub link), data exchange modelling platform, documenting integrated assessment, energy system, and sectoral modelling capabilities, inputs, and outputs, developed by the H2020 PARIS REINFORCE project and supported by H2020 projects NDC ASPECTS and ENCLUDE as well as Horizon Europe projects IAM COMPACT and DIAMOND. […]
The CD-LINKS project was exploring the complex interplay between climate action and development, while simultaneously taking both global and national perspectives and thereby informing the design of complementary climate-development policies. The CD-LINKS consortium brought together national and global integrated assessment modeling groups from Europe, China, India, Brazil, Russia, Japan and the USA […]
The “IAMC 1.5°C Scenario Explorer ” presents an ensemble of quantitative, model-based climate change mitigation pathways underpinning the Special Report on Global Warming of 1.5°C (SR15) by the IPCC published in 2018. The ensemble was also used and extended in the IPCC’s Special Report on Climate Change and Land (SRCCL, […]
The “AR5 Scenario Database” documents the long-term scenarios assessed in the Fifth Assessment Report (AR5) of IPCC Working Group III. These scenario database supported the assessment in Chapter 6 on “Transformation Pathways” as well as a range of sectoral chapters in AR5. It comprises close to 1200 scenarios from more […]
The Shared Socioeconomic Pathways (SSPs) and the related integrated assessment scenarios are part of a framework that the climate change research community has adopted to facilitate the integrated analysis of future climate impacts, vulnerabilities, adaptation, and mitigation. The framework is built around a matrix that combines climate forcing on one […]
The “RCP Database” aims at documenting the emissions, concentrations, and land-cover change projections of the so-called “Representative Concentration Pathways” (RCPs). A handshake document between the Integrated Assessment and Climate Modeling community coordinated the data provided as input for the “Coupled Model Intercomparison Project” 5 (CMIP5). The final RCPs have been […]
