Economic growth and environmental sustainability are fundamentally incompatible goals.

This debate represented a collision between hard physical sciences and economic optimism, resulting in a decisive victory for the Pro position. The Pro side successfully framed the debate not merely as an economic discussion, but as a confrontation with thermodynamic reality. By consistently grounding their arguments in the distinction between relative and absolute decoupling, and emphasizing the aggregate global material footprint over isolated national successes, Pro dismantled the foundation of the Con case.

Con performed competently, particularly in the early rounds, by highlighting the shift toward service-based economies and citing data regarding nations that have achieved some form of decoupling. However, Con’s reliance on the statistic that "92% of global GDP is in economies showing signs of decoupling" became a liability in Round 3. Pro effectively exposed this as a "rate fallacy"—demonstrating that while decoupling is occurring, the rate is insufficient to meet planetary boundaries within a finite carbon budget, and often relies on outsourcing emissions (leakage).

The turning point occurred in the rebuttals, where Pro shifted the burden of proof. Pro argued that proving some decoupling is possible does not prove infinite growth is physically sustainable. Con failed to effectively counter the argument regarding the "material floor" of the economy—the idea that even a digital economy requires physical infrastructure (servers, rare earth metals) that cannot be infinitely expanded. Ultimately, Pro’s adherence to the strict definition of "infinite" growth on a "finite" planet provided a logical fortress that Con’s examples of "green growth" could not breach.
