For decades, economic growth has been synonymous with rising living standards—and equally, with soaring carbon emissions. As climate change accelerates, the question of whether continued growth is compatible with a habitable planet has become critical. A recent podcast featuring economists Nick Stern and Jason Hickel explores two opposing approaches: green growth and degrowth.
The Case for Green Growth
Nick Stern, a professor at the London School of Economics, advocates for green growth. This model suggests that economic expansion can continue if it prioritizes environmentally sustainable industries. The idea is simple: shift investment toward renewable energy, efficient technologies, and circular economies to decouple growth from pollution.
However, critics point out that history shows technological progress alone has not stopped emissions from rising. The rebound effect—where increased efficiency leads to increased consumption—often undermines environmental gains. Moreover, the transition to green industries requires massive upfront investment, and the pace of change may not match the urgency of the climate crisis.
The Degrowth Argument
Jason Hickel, a political economist at the Autonomous University of Barcelona, argues for degrowth. This approach calls for a deliberate reduction in resource-intensive sectors—fossil fuels, fast fashion, industrial agriculture—while prioritizing social and ecological well-being. Degrowth is not about austerity; it’s about shrinking the parts of the economy that harm the planet while expanding essential services like healthcare, education, and renewable energy.
The main challenge with degrowth is its political and economic feasibility. Reducing GDP, even in specific sectors, clashes with mainstream economic thinking. It would require significant shifts in consumer behavior, corporate practices, and government policies. But if unchecked growth leads to climate collapse, degrowth may become an unavoidable necessity.
Why This Matters
The debate between green growth and degrowth is not just academic; it shapes policy decisions at the highest levels. The current emphasis on growth-at-all-costs ignores the physical limits of our planet. As ecological crises intensify, failing to address the root cause—relentless expansion—could lead to catastrophic consequences.
Ultimately, the choice between these approaches will determine whether we prioritize short-term economic gains or long-term planetary survival. The question is no longer whether growth is possible, but whether it is worth it.
