Short description:

The report presents WILIAM, a next-generation integrated assessment model (IAM) developed by the HORIZON 2020 LOCOMOTION project consortium to help policy-makers explore sustainable pathways toward a net-zero future. Combining heterodox economics, innovative features, and user-centered design, WILIAM allows policy-makers to make better decisions amid complexity and uncertainty. The model includes many innovative features, such as the modelling of material recycling and hydrogen energy, integration of planetary boundaries, and setting goals for sufficiency and equality. It also provides an overview of the WILIAM model and how policy-makers can use it to address real-world sustainability issues. Chapter 1 outlines how scientific models inform policy-making and the urgent need for rethinking current approaches. Chapter 2 reviews WILIAM’s design, modules, components and limitations. Chapter 3 outlines applications of the new IAM in climate policy development. Chapter 4 presents model modifications tailored to different stakeholder groups. The conclusion summarizes the vision for rewiring the climate policy agenda.
