Steel is one of the essential drivers of infrastructure development, urbanization, and industrialization of any country. It plays a key role in economic expansion, contributing significantly to a country's gross domestic product (GDP). As demand for steel rises globally, there is a critical need to modernize existing capacities and develop new facilities. However, a significant challenge in the iron and steel sector is reducing carbon dioxide emissions, as they contribute about 7% of greenhouse gas (GHG) emissions globally. Implementing competitive low-emission routes for the direct reduction of iron across existing steel production and new plants can significantly lower future emissions. The future of sustainable steelmaking lies in hydrogen-based direct reduction of iron, which integrates renewable energy and advances the hydrogen economy. This pathway provides a low-emission route to decarbonize steelmaking while ensuring long-term sustainability and competitiveness when supported by governments.

This study covers the following topics:

It assesses global CO? emissions in steel production and details the carbon footprint of steelmaking pathways and their influence on economic stability and industrial growth.
