The road to green zinc…decarbonisation of zinc production
The production of zinc from ore to metal emits around 40 million tonnes of CO2 every year. Emissions from zinc mines and smelters are much lower in comparison to other metals, but to move towards low-carbon zinc production, producers need to take action now to decarbonise production and meet climate targets. Emissions are driven by …
