Systems Modelling
Published: 2 November 2026
To support decision makers understand and balance the multiple social and environmental goals required to achieve a just and sustainable transitions we have developed two system-modelling approaches: a multi-objective optimisation framework and a dynamic system model.
Led by researcher Cris Hasan, our system-modelling approach aims to support decision-making around achieving just and sustainable transitions. This includes two complementary areas of work:
1. Multi-objective optimisation
Achieving a just and sustainable transition requires the pursuit of multiple social and environmental targets. Two primary barriers impede this process: (1) targets are often in conflict with each other, and (2) policies aimed at these targets are commonly planned in isolation, neglecting complex interdependencies in the system. To address these challenges, we have constructed a modelling framework that evaluates the holistic impact of policies and decision-making on sustainability targets while capturing system interdependencies in a policy-target network. This framework accounts for trade-offs between conflicting targets by dynamically reallocating resources to the most impactful and efficient policies.

2. Dynamics modelling of socio-ecological systems
We have developed a proof-of-concept mathematical model that captures the interdependencies between social goals and ecological boundaries.
The model is supplemented with an interactive user-friendly dashboard for exploring and comparing a range of hypothetical scenarios, allowing stakeholders to swiftly navigate complexity and understand inherent trade-offs among interconnected targets.
