I’ve been spending a lot of time recently getting my head around CBAM, the EU’s Carbon Border Adjustment Mechanism, and thought the best way to really understand it was to try and explain it to others. So I challenged myself to build something interactive, with a bit of help from Claude. The result is Save the Container: a browser game where a container ship sails from Shanghai to Rotterdam, you learn one CBAM concept per level, and if you get the question wrong, your container drops into the sea. No code written by me, just ideas, iteration, and a lot of prompting.

It covers everything from how the charge is calculated, to supplier data obligations, to why the production route of your steel matters more than you’d think. Give it a play if you work in trade, procurement or sustainability. It takes about five minutes and leaves you with a solid grounding in one of the most significant trade policy changes in a generation.
