Pathways to Carbon Neutrality in the Copper Industry

What is it about?

The research explored decarbonization pathways for the copper industry in the context of achieving carbon neutrality, employing material flow analysis and life cycle assessment methods. It analyzed 12 subscenarios related to international trade, circular economy, technology evolution, and environmental market factors. The research predicted a 62.3% increase in refined copper consumption in China by 2060 compared to 2020, with greenhouse gas emissions reaching 9.1 million tonnes CO₂-eq. Technology evolution and environmental market factors were identified as significant contributors to emissions reduction, accounting for 26.4% and 47.2% of reductions, respectively. The research highlighted the importance of international trade and circular economy in the carbon peaking stage, while noting that imported and domestic secondary copper will form the primary supply in the long term. Furthermore, a policy combination scenario could reduce emissions to 0.5 Mt CO₂-eq by 2060, with enhanced policies like material substitution and carbon emission trading suggested to support net-zero emissions. The research recommended regulating industry structure and accelerating green circular chain construction to ensure a sustainable copper supply.
