A new study assesses how China can optimize electric arc furnace (EAF) steelmaking under its carbon neutrality target. Using the AIM-China/Steel model, it evaluates provincial potential by integrating scrap supply, interprovincial transport, and energy costs. The results show that EAF deployment is jointly determined by scrap availability and transport feasibility. In scrap-scarce regions, expansion is constrained, requiring cross-regional flows or alternative low-carbon technologies.

A new study examines how carbon pricing affects Japan’s transport sector and regional economies. Using a multi-regional computable general equilibrium (CGE) model, the research evaluates the impacts of a 10% emission reduction target. The results indicate that achieving this target requires a carbon price of approximately 4,153 JPY per ton of CO₂, with only a modest aggregate GDP loss. The policy also reshapes transport demand, shifting activity away from high-emission modes such as water and air transport toward lower-carbon alternatives like rail. The findings highlight that policy design—particularly the coverage of the transport sector and the redistribution of carbon tax revenues—plays a crucial role in balancing efficiency and regional equity.

The prevailing international environment is marked by rising geopolitical tensions, necessitating an in-depth examination of its underlying mechanisms. In a recent research article, a researcher from Waseda University highlights that democracies can weaken through shifts in elite alliances triggered by international economic and geopolitical situations, especially emphasizing the crucial role of economic and political elites, such as business leaders and legislators.

According to new research, the US-Israel-Iran War is striking at the heart of global food production, pushing tens of millions of people into abject poverty. Although a fragile ceasefire has temporarily halted the intense hostilities that erupted on February 28, the core problem remains unresolved: Iran’s move to disrupt the passage of trade and oil through the Strait of Hormuz, followed by the United States’ blockade of Iranian ports.

Indiana University is now offering its acclaimed essential skills course in generative artificial intelligence — GenAI 101 — to everyone worldwide, free of charge.

Faculty and staff at the IU Kelley School of Business developed one of the largest generative AI courses offered by a leading research university. Since it launched in August, more than 114,000 students, staff and faculty have enrolled in GenAI 101. In October, IU expanded access to its more than 805,000 alumni worldwide; thousands have enrolled since then.

As temperatures rise across the U.S., are Americans really packing up and leaving? New research reveals a more complex story. Analyzing nationwide county-level data, the study finds that jobs, housing costs and quality of life – not heat alone – drive migration decisions, at least for now. While extreme temperatures may deter newcomers, they aren’t triggering mass departures. Instead, climate subtly shapes where people choose to live, working alongside economic and social forces rather than leading the way.
