The Public Forum September–October topic vote closes on 31 July. The winning resolution is announced on 1 August. Here is a full strategic breakdown of both options — what each resolution demands, what the strongest cases look like, and how to prepare before the official announcement.
The Two Topic Options
Option 1 — Resolved: The United States federal government should enact a moratorium on hyperscale data center construction.
Option 2 — Resolved: The United States federal government should enact an emissions trading system.
Option 1: Moratorium on Hyperscale Data Center Construction
This would be one of the most technically demanding Public Forum resolutions in recent memory. Understanding it requires knowing what a hyperscale data centre actually is.
What Is a Hyperscale Data Center?
Hyperscale data centres are massive computing facilities — typically operated by Amazon Web Services, Microsoft Azure, Google Cloud, and Meta — that house hundreds of thousands of servers and consume enormous quantities of electricity and water. A single hyperscale facility can draw as much power as a small city. As AI training workloads grow, the power demands of these facilities are increasing sharply.
In 2024 and 2025, power grid operators across the United States flagged data centre expansion as a significant threat to grid reliability. Several US states have experienced grid stress during peak demand periods partly attributable to data centre load growth.
The Affirmative Case
The AFF case rests on environmental and grid reliability grounds. A moratorium pauses new construction until adequate clean energy infrastructure is in place to power these facilities without grid stress or fossil fuel reliance. The AI boom is being built on coal and gas. The AFF argues that a temporary halt is justified to prevent locking in decades of carbon-intensive infrastructure.
A secondary AFF line focuses on water consumption. Hyperscale data centres use millions of gallons of water daily for cooling. In drought-affected regions, this creates a genuine public resource conflict.
The Negative Case
The NEG case rests on economic and strategic grounds. Hyperscale data centres are the infrastructure backbone of the US digital economy, AI development, and national security systems. A moratorium unilaterally imposed by the US government would slow AI development while China, the EU, and other competitors continue building. The NEG can also argue that the power and water concerns are best addressed through regulation and clean energy investment — not a moratorium that halts all new construction regardless of how it is powered.
The NEG can also run a counterplan: rather than a moratorium, require that all new hyperscale construction be paired with dedicated clean energy generation, essentially making the industry self-funding on renewable power.
What to Research Before 1 August
US grid reliability data from NERC and regional transmission organisations. AI power consumption projections from Lawrence Berkeley National Laboratory. Water usage data from the Alliance for Water Efficiency. The economic footprint of the data centre industry by state. China's data centre expansion timeline as a competitive benchmark.
Option 2: Emissions Trading System
An emissions trading system — also called cap-and-trade — is a market-based environmental policy mechanism. The government sets a total cap on emissions, issues permits equal to that cap, and allows companies to buy and sell permits. Companies that can reduce emissions cheaply do so and sell spare permits to those for whom reduction is more costly. The cap declines over time, driving overall emissions down while minimising economic disruption.
The Affirmative Case
The AFF case rests on market efficiency and environmental outcome. The EU Emissions Trading System is the world's largest and longest-running cap-and-trade programme — it has driven significant emission reductions in covered sectors while generating revenue that EU member states have used for clean energy investment. The AFF argues the US should implement a comparable system at the federal level.
A secondary AFF line addresses the current fragmented approach: the US currently has a patchwork of state-level systems (California, the RGGI states) with no federal coherence. A federal ETS creates a unified price signal that drives investment at scale.
The Negative Case
The NEG case has two strong lines. First: distributional effects. Emissions trading systems raise energy costs, and energy costs as a percentage of income are higher for lower-income households. The NEG argues that an ETS is a regressive policy that disproportionately burdens those least able to bear it — and that carbon dividends or direct regulation are more equitable alternatives.
Second: the leakage problem. If the US imposes carbon costs through an ETS but trading partners do not, US manufacturers face a competitive disadvantage and may offshore production to lower-cost, higher-emission jurisdictions — resulting in carbon leakage that offsets domestic reductions.
What to Research Before 1 August
The EU ETS structure, history, and emissions outcomes. The Regional Greenhouse Gas Initiative in the northeastern United States. The economic literature on carbon leakage and border carbon adjustments. The distributional analysis of cap-and-trade versus carbon tax versus direct regulation. Congressional history of climate legislation to understand the political feasibility dimension.
Which Topic Is More Likely to Win the Vote?
This is genuinely difficult to call. The data centre moratorium is more novel and would generate more distinctive debates — but it is also harder to brief and requires more technical background. The emissions trading system is more familiar territory for experienced PF coaches and has deeper existing literature.
Prepare both. Two days of preparation on a topic you end up not debating is far less costly than two days of nothing on a topic you will spend the next four weeks on.
