Abstract
The projected GHG emissions cannot reach the climate goal under any SSP. Further efforts on lowering per capita in-use metal stocks and GHG emission intensity of metal production and promoting recycling are the key to achieve the climate goal.

This study quantified the implications of shared socio-economic pathways (SSPs) for global greenhouse gas (GHG) emissions associated with metal production for 2010–2100, and explored effective measures to reduce GHG emissions for achieving climate goals
We show that SSPs have a significant effect on the GHG emissions associated with metal production

Climate change is an urgent global challenge. Reduction in global greenhouse gas (GHG) emissions of 41–72% by 2050 and 78–118% by 2100 compared with the level in 2010 are required to maintain the temperature change below 2 1C relative to preindustrial levels.[1] The current society heavily relies on metals for a variety of purposes, which is predicted to accelerate in the future owing to the global population and economic growth.
