At present, the climate change has become the threat and challenge globally. As a large carbon emitter, the iron and steel industry is an important part for achieving the goal of peak carbon dioxide emissions and carbon neutrality in our country. The national carbon emission trading market, as a significant policy tool to reduce greenhouse gas emissions, provides the trading platform for contract fulfillment of carbon quota for enterprises. In the paper, the contract fulfillment scheme of carbon emission quota for iron and steel industry into the carbon emission trading market is analyzed based on the current experiences and methods for power industry participating in the carbon emission trading considering six situations that enterprises could face. Moreover, the suggestions are proposed from such aspects as the low carbon management, precision of carbon emission data and applications of low carbon metallurgical technologies to promote enterprises to transform to be green and low-carbon.
