Air taxation represents one of the most ambitious attempts to integrate environmental limits into modern economic systems. By attaching a price to emissions, governments hope to reshape industries and accelerate the transition toward cleaner technologies. But the effectiveness of these systems remains uncertain.

Global manufacturing is reorganising. As companies rethink supply chain risk, production is moving closer to major markets, and Mexico is becoming one of the most important industrial platforms in North America. This episode explores the rise of the Mexican industrial cluster and the deeper system behind it: logistics corridors, cross-border production networks and the growing pressure on energy, water and infrastructure that follows rapid industrial expansion.

Air is essential for life, yet it is rarely treated as a fundamental right. This episode explores a growing global question: if everyone depends on the air to survive, does society recognise a right to breathe safely and who is responsible when that right cannot be guaranteed?

Every day we take around 20,000 breaths, most of them in cities where the air is shaped by traffic, industry and global infrastructure. Today almost the entire world’s population already lives in places where air pollution exceeds World Health Organization guidelines, and by 2050 nearly two-thirds of humanity is expected to live in urban areas. From the deadly London smog of 1952 to the winter haze over Delhi and the historic smog that once covered Los Angeles, cities reveal how modern urban life quietly transforms the atmosphere above us. This episode explores the invisible layer of air that millions of people breathe every day and the systems that shape it.

This episode examines developments around the Strait of Hormuz, a key maritime chokepoint for global energy trade. Recent security incidents involving commercial vessels, together with increased regional attention around Iran and the US, are influencing shipping routes, oil flows and maritime logistics.

Season 4 opens with a look at the most invisible layer of the global system: the atmosphere. This episode explores how modern industry, energy production, and transportation have quietly turned the air into a vast repository of economic waste. Understanding this hidden interaction between the economy and the atmosphere is the starting point for the new season of Beyond the Business.

Security tensions in the Red Sea are forcing ships to reroute and adding pressure to global supply chains. In this Business Weekly episode we look at how disruptions around the Suez corridor are reshaping shipping routes, transit times and logistics planning.

The final episode of Season 3 connects the main topics of the season including dead zones, ocean infrastructure, shipping, energy systems and deep sea resources. It reflects on how human activity is becoming part of the ocean system and why its long term signals matter.
