The cost of phasing out SCCPs was 18.11 to 30.88 billion yuan, mainly from the substitution in downstream industries. The cost under the 5-year control scenario was less than the 10-year scenario. The benefit of phasing out SCCPs in China was 146.26 billion yuan. The 5-year control scenario was suggested for phasing out SCCPs.
