Modelling Degrowth Policies with System Dynamics: Towards Policy Coherence
Using the iSDG-Sweden model, this study evaluates degrowth policies in Sweden from 2026–2050. Results show that policies only work effectively when implemented together, combining reduced high-impact production, shorter working hours, and wealth redistribution. This package lowers environmental pressures while reducing poverty, inequality, and unemployment. While financially viable in the short term, long-term debt risks suggest deeper structural reforms may still be needed.

Assessment of Development Scenarios to Reach Net-Zero by Mid-Century: A System Dynamics Modelling Approach for South Africa
South Africa's net-zero transition is best pursued as an integrated developmental shift rather than a narrow decarbonisation exercise. Using the iSD system dynamics model, the report shows a holistic, multi-sector scenario outperforms the baseline—boosting GDP, cutting emissions and poverty, and improving access to electricity, water and nutrition, with electricity the key enabling system. However, persistently high inequality and incomplete decoupling of growth from consumption mean it is not yet a fully just transition, requiring stronger distributive and circular-economy measures.

SDG for All: Africa
A research from Earth4All, utilizing the Millennium Institute iSD Model, shows the policy levers needed to ensure that the SDGs are met in Sub-Saharan Africa by 2100. The report ‘SDGs for All: Africa’ equips policymakers with practical solutions designed to accelerate SDG implementation and to respond to the planetary emergency. It concludes that policymakers can step up the implementation of the SDGs by 2030 and beyond and achieve wellbeing for all. But this is only possible by enacting five ‘extraordinary turnarounds’ that break with current trends.
