Due to the increasing climate challenges faced by the world, low-carbon development has increasingly become a global consensus, and the green low-carbon transformation of the industry has become the key to solving the bottleneck problems of environment, energy and resources. Steel production is the largest emitting manufacturing sector on the planet, accounting for 7% of total man-made greenhouse gas emissions. North America has been committed to decarbonization, and decarbonization in the NA region is happening at full speed. North America currently has the lowest carbon steel production in the world, as a result of a combination of economic, financial and technological factors that have made the North American steel industry a poster child for green steel production, contributing to the prevention of climate change and global warming.
