led by the China International Development Knowledge Center and supported by BHP Billiton, the project "Carbon Peaking, Carbon Neutral China Strategy and Global Outlook" was launched in Beijing. China announced that it will increase its nationally determined contribution and strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. We will also respond positively and actively explore low-carbon transformation technologies that are effective and can be produced on a large scale, so as to promote the low-carbon steel production process. Contribute to the global environmental protection cause.
