Integrated Assessment Models (IAMs) develop long-term mitigation scenarios which play an essential role in the development of IPCC reports. These models, however, have been criticized for proposing solutions that are challenging to carry out due to a lack of consideration of social and institutional challenges. In the paper "A multidimensional feasibility evaluation of low-carbon scenarios by person" (Brutschin, et al., 2021), scientists proposed a versatile, multidimensional framework that allows for comparisons between decarbonization pathways by quantifying feasibility concerns. This online, interactive tool was developed to complement this paper and allows the user to examine this framework in more detail.

The Shared Socioeconomic Pathway (SSP) Extensions Explorer is a tool for visualizing and downloading quantitative elaborations of the Shared Socioeconomic Pathways (SSPs), which emerged in the literature since the publication of the original set (e.g., GDP, population) of SSP-related indicators. The tool hosts scenarios of indicators such as Gender Inequality Index, Governance, Rule of Law, Human Development Index, and Migration Flows.

The Fair Mitigation Finance Explorer is the web app accompanying the paper 'Fairness considerations in global mitigation investments'. Users can select various indicators with a variety of weights to explore the ‘fair’ regional contributions to near-term regional mitigation investment needs. With this information, the web app determines the ‘fair-share’ regional contributions to their respective regional ‘cost-effective’ investment needs.

A host of scientific chemistry and climate model experiments explore responses of the global atmosphere and climate systems to possible future changes in emissions of air pollutants and greenhouse gases. The Pollution Management research group (formerly AIR program) has used its GAINS model to develop a set of global emission fields of nine substances that provide consistent sets of future sectoral emissions for well-specified assumptions on economic development and the effectiveness of dedicated emission control policies.

Welcome to the world of PlantFATE, a novel eco-evolutionary vegetation model designed to unravel the intricate dynamics of forests and their response to environmental change. PlantFATE stands as a powerful tool to guide conservation efforts, inform policy decisions, and foster a deeper appreciation for the wonders of nature. Embark on a journey through the intricate tapestry of forest resilience with PlantFATE as your guide.

Scenarios as a decision-making tool help us to better understand the implications of a wide range of future possibilities considering existing development, strategies, and global interdependencies. Scenarios should be co-produced with their users, most often planner and decision makers.

Role-play simulations are a transdisciplinary method for engaging diverse stakeholders beyond traditional policy- and decision-making communities in an informed and inclusive public debate around the governance of complex socio-environmental challenges. 

Design Thinking (DT) is a participatory approach that focuses on understanding user-design problems with a variety of “products” and to create and test innovative problem solutions - these may include physical goods but also non-physical products such as services, policy instruments etc.

Integrative qualitative system mapping (IQSM) enables the systematic and transparent integration of diverse qualitative data. It is particularly useful as a tool supporting mixed methods research addressing nexus issues in sustainable development.  

Spatial layers of global importance highlighting the upper potential value of conserving biodiversity, carbon and water assets under different area-based conservation targets.

The ibis.iSDM package provides a series of convenience functions to fit integrated Species Distribution Models (iSDMs). With integrated models we generally refer to SDMs that incorporate information from different biodiversity datasets, external parameters such as priors or offsets with respect to certain variables and regions.

MAGICC is a reduced complexity Earth system model that has been widely used in climate science for over three decades, most notably in multiple IPCC reports. It is most often used in a probabilistic setup, providing information not only about our best-estimate of future climate change but also the uncertainty that arises from interactions between the Earth system’s many components. MAGICC is also as the climate component in multiple integrated assessment models (IAMs). 

The SD-ET analysis provides a novel methodological framework of using observed historical patterns of technological change to test the plausibility of future scenarios of technological change to meet climate change mitigation goals.

The Energy and Carbon Emissions Inventory Database (ECDB) compares major global inventories of primary energy use and carbon emissions.

A historical database of energy use by country or region, energy level, sector, energy carrier, and end-use type.

Pathfinder is designed to fill a perceived gap within the existing simple climate models by fulfilling three key requirements: (1) the capacity to be calibrated using Bayesian inference, (2) the capacity to be coupled with integrated assessment models (IAMs), and (3) the capacity to explore a very large number of climate scenarios to narrow down those compatible with limiting climate impacts.

The DisruptSC model assesses the indirect economic impacts of disasters by explicitly quantifying the disturbances on supply chains. It simulates, in space and time, how transport infrastructure disruptions perturb the flows of goods in supply chains and how these perturbations affect households, firms, and trade.

The CAMALIOT mobile app for crowdsourcing is used to collect data transmitted by the Global Satellite Navigation System (GNSS) for scientific applications such as weather forecasting and improving positional accuracy

This high-resolution electrification dataset for Sub-Saharan Africa is developed at the Energy Program of the International Institute for Applied Systems Analysis (IIASA) in cooperation with the Fondazione Eni Enrico Mattei (FEEM).

This Scenario Explorer hosts the results from the Integrated Solutions for Water Energy and Land project (ISWEL).
