The paper presents AMES, an open-source, multi-sector macroeconomic model developed by the Stockholm Environment Institute. AMES is designed to integrate with the Low Emissions Analysis Platform (LEAP) to create a hybrid energy-economy model. Unlike neoclassical models, AMES is based on structuralist theory, allowing it to simulate structural change and hysteresis, where energy investments can lead to persistent positive impacts on GDP and employment. It is specifically tailored for the economic conditions of low- and middle-income countries, focusing on demand-led growth and capacity utilization rather than assuming full employment and competitive market equilibrium.

This chapter describes the Long-range Energy Alternatives Planning system Integrated Benefits Calculator (LEAP-IBC), a model developed by the Stockholm Environment Institute to estimate the impacts of policy scenarios on pollutants, human health, and other endpoints, specifically highlighting its application in Bangladesh.

The Climate Impact Equity Lens (CIEL) is a tool that personalizes the economic consequences of climate change by comparing individual avoidable damages against the savings gained from not paying for emissions reductions. Unlike traditional climate-economic models that aggregate data by region and use temporal discounting, CIEL focuses on individual archetypes and reports results by decade through 2200. It utilizes data from the Stockholm Environment Institute's CRED model to show that while some individuals may be 'net gainers' in the short term, the vast majority will become 'net losers' as climate impacts intensify, particularly those with high vulnerability in terms of income, geography, and economic sector.

The COMPACT Local Government Collaboration Model is a catalytic tool developed by the Public Affairs Research Institute (PARI) to foster collaboration among municipal administrations, councillors, and the local community. The model employs a five-step process—Purpose, Making Sense of the Challenge, Vision and Hope, Implementing and Adapting, and Reflection and Learning—to move beyond traditional problem-solving. The model was piloted in 2025 in the Blue Crane Route Local Municipality (focusing on the Pearston water crisis) and the Newcastle Local Municipality (focusing on tuckshop regulation and local economic development). A subsequent train-the-trainer workshop was held in August 2025 in Gauteng to refine facilitation materials and guide representatives from SALGA, PARI, and the pilot municipalities.
