Around 70% of the emissions arising from aluminium production came from China, despite it only producing 57% of the global total output. This reflects the dominance of coal in China as a power source for both smelting and refining aluminium, with coal accounting for 85% of the energy used for smelting and 87% of the energy used in refining.

This temperature is hot enough to start forging most steels and other metals. Step 4: Maintain a steady flow of wood fuel. Once you have your fire at the correct temperature, it's time to start forging! You'll need to maintain a steady flow of wood fuel during the forging process, so it's important to keep replenishing your fire throughout.
