China’s carbon emissions trading system (ETS) helps the country slow down industrial solid waste accumulation

: This study reveals that the carbon ETS can serve as a potent policy instrument for addressing a broader spectrum of industrial pollution beyond its primary carbon-cutting goal. To strategically strengthen the identified pathways through which the ETS mitigates industrial solid waste, a complementary policy mix is essential. This should include measures to lower financing barriers for waste treatment upgrades, incentivize R&D and technological progress, and support energy efficiency projects alongside carbon trading.
