Mandates
The targets, laws and pledges that send people to a model: what each requires, by when, and the question it raises.
Many people arrive at a model because something binds them: a treaty target, a national law, a council motion, a court order. Each entry here says who issued the mandate, whom it binds, what it requires by when, how progress against it is counted, and which use case it turns into. A mandate is a reason to model, not a model; the engines and data sit one link away.
The global biodiversity agreement adopted by the Parties to the Convention on Biological Diversity in December 2022: four goals for 2050 and twenty-three targets for 2030, which each Party committed to turn into national targets.
