Nippon Steel's US Green Investment Can 'Simultaneously Achieve' Job Creation, Decarbonization, and Air Pollution Reduction, According to Indiana University Research

(April 8, 2026, Tokyo) The Environmental Resilience Institute (ERI) at Indiana University and US climate research firm 5 Lakes Energy announced research findings demonstrating that green investments can simultaneously achieve job creation, decarbonization, and air pollution reduction. This report indicates that Nippon Steel's green investment in US Steel's Gary Works in Indiana could create up to approximately 59,000 new jobs and reduce annual CO2 emissions from the steelmaking process by 4.1 million tons [1].

The report also addresses the serious air pollution issues at the Gary Works, suggesting that transitioning from coal-fired blast furnaces to green hydrogen-based steelmaking could halve carcinogenic air pollutants. Air pollution from three steel mills in Northwest Indiana, including Gary Works, is estimated to result in approximately $75 million in annual healthcare costs, 230 emergency room visits for respiratory issues, and tens of thousands of lost work and school days [2].

Gabriel Filippelli, Executive Director of the Institute and co-author of the report, stated, "Residents around Gary have suffered from the effects of carcinogenic substances due to air pollution from the steel industry for generations." He added, "Nippon Steel's plan to invest $3.1 billion in Gary Works could be a historic turning point, leading the industry and the community in a better direction. However, this study clearly shows that if the transition to clean, modern steelmaking facilities does not progress, public health and employment will continue to deteriorate, even if coal-fired equipment is extended."

Nippon Steel plans to invest $350 million in relining the blast furnace at Gary Works, with construction expected to begin in May this year. This refurbishment is projected to extend the operation of the aging coal-fired blast furnace until the 2040s. However, the report points out that even with significant investment in refurbishment, competitiveness will not be restored, merely postponing the decline of the business structure [4]. According to local media, US environmental groups are currently seeking a delay in permits associated with this refurbishment [5].

"Nippon Steel plans to invest a total of $3.1 billion in Gary Works, but the use of over $2 billion of that amount is currently unclear. We hope for investments that transition from coal dependence to clean technology, creating a 'win-win-win' for employment, health, and climate," said Roger Smith, Asia Representative for SteelWatch.
