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...
General:
- 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'.
Political:
Social:
- 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!
Economical:
Yes, just about every book on Econometrics or aiming about 'financial literacy' (many others know any good resources on that...)
Environmental:
Most of the resources I know... mentioned in other answers and :
