Steel is one of the focal points of the government’s decarbonisation ambition. In addition to national policies, steel-specific measures were introduced in 2021. A detailed action plan dedicated to peaking carbon emissions in the steel industry is almost ready and is expected to be made publicly available shortly.
In 2021, the most straightforward measure the government took to restrict steel emissions was the cap on steel production, which sets up a mandate of no year-on-year increase in steel production compared to 2020. According to the NBS statistics, an immediate concrete result is that in 2021 China’s crude steel production declined by 31.9 Mt to 1032.8 Mt, marking the first year-on-year decline over the past six years.
To reduce domestic steel production further, the Ministry of Finance decided to restrict exports of steel products by removing tax rebates for exports of most steel products from 1 May. According to the announcement, tax rebates for cold-rolled sheets, colour-coated coils, hot-rolled coils, high-alloyed rebar, seamless pipes, stainless steel sheets, and plates will be completely eradicated, from its previous 13%. The duty for pig iron exports was lifted from 10% to 15%, and the export duty for steel scrap remains unchanged at 40%.
BBN is also actively responding to low-carbon and environmentally friendly production and is concerned about changes in the global environment.
JIS G 3106 SM400A hot rolled structural steel plate is BBN's most popular low carbon production product. the information is as follows:
