Before listing 'resources', let me start with some official documents (e.g. to clarify the difference of sustainable math and math for sustainability, see xkcd:Sustainable :-).
The official UN Site lists the 17 Goals for sustainability; especially Goal 4: Education. Still debating what this all means, I find the paper by Brundiers et. al. (2021, see below for reference) gives a nice overview. Although the article is behind a paywall, the relevant figures are available on researchgate, put short: different 'competencies' intertwined yield what is called 'key competencies for sustainable development'.
Math relevant: problem-solving, strategic-thinking, ...
So to speak: All math is relevant! To me, what's important is not to think of the modelling aspect only. In math we need to sort this out a little more!
In the UN-model, there are different aspects of 'eduacation for sustainable development' (ESD) mentioned: Relations to environmental, economic, social and political
questions. I like the 'Math of Planet Earth' Series exactly for this reason: It shows more that just applications of differential equations to environmental questions.
Let me first add: UNESCO & MGIEP have a wonderful text about general aspects for textbooks in relation to ESDs and explicate that in examples. What I find interesting is that they don't start in high school. It starts in Kindergarten: Kids getting their grips to quantities, measurement and numbers. That's where maths starts relating to ESD: Discovering you in the world around. They list different affordances that are also met by resources that are not specifically mentioned in relation to 'sustainability' (see p. 50), such as:
- use real world contexts that relates to the life of students
- use real data in your teaching, not given numbers (or discuss with students realistic guesses)
- don't oversimplify, but enable students to grapple with complexity ('corse at the appropriate level)
- respect, courage and agency in teaching are important; thus it is not only about the material but also how you enact with them when teaching.
In this broader sense, I would like to add different resources, trying not to repeat the ones already mentioned in other answers.
Also, I didn't check the list for the age group appropriate for the materials. And of course this is far from complete...
- Kaslik (2016) Math in a Vibrant and Sustainable Society. Resources on different topics: I like it because it (now) drives on a positive path showing opportunities; many other models are quite pessimistic; this book startet like that and switched...
- Issue to Action: Maths Nice examples related to climate, gender and migration.
- Community Based Math Project from Philly shows ways how to connect mathematical questions to your local environment and see the world around you through 'math lens'.
- Steen (2001) Mathematics and Democracy is a classic as well, showing the importance to be able to think about quantities in everyday life and different aspects of it.
- Radical Statistics. Talking about the use of 'real data' and where to find it; e.g. on
- GapMinder. Still one of the best tools to explore real world data!
Yes, just about every book on Econometrics or aiming about 'financial literacy' (many others know any good resources on that...)
Most of the resources I know... mentioned in other answers and :
