What they cannot agree on is how to deal with the situation, as a lively panel hosted by Fastmarkets during LME Week at the end of October showed.

One argument is that if you’re producing high-carbon metal, you should reduce your carbon footprint or stop operating altogether, something that will ultimately happen when consumers and governments reject your products.

This will slow not only these countries’ growth but also significantly trim aluminium demand there.
Both sides are...
