English Summary

Chatham House argues that repealing the 2009 EPA endangerment finding is a strategic own goal: it may reduce near-term regulatory pressure, but it undermines US long-term economic and technological power. The paper cites estimates that rollbacks could add 7.9-15.3 billion metric tons of emissions by 2055, while also locking US automakers into legacy internal-combustion technologies as global EV adoption accelerates. It contends that lower regulation does not solve competitiveness because EVs often have lower lifetime operating costs, and global demand is shifting toward cleaner vehicles, with EV sales reaching 20.7 million in 2025. Strategically, the implication is that US policy should treat emissions and efficiency standards as industrial policy, sustaining investment in batteries, electrification, and clean-tech supply chains to avoid ceding market share and influence to China.

中文摘要

研究所主張,撤銷美國環保署(EPA)2009年「危害認定」(endangerment finding)是一種戰略性自傷:此舉或可在短期內減輕監管壓力,卻會削弱美國長期的經濟與科技實力。該文援引估算指出,相關鬆綁措施到2055年可能額外增加79億至153億公噸排放,同時在全球電動車加速普及之際,將美國汽車製造商鎖定於傳統內燃機技術路徑。文章認為,放寬監管無法解決競爭力問題,因為電動車在全生命週期營運成本上往往更低,且全球需求正轉向更潔淨車輛;2025年電動車銷量已達2,070萬輛。從戰略角度看,美國政策應將排放與能效標準視為產業政策工具,持續投入電池、電氣化與潔淨科技供應鏈,以避免將市場份額與影響力讓渡給中國。

    The article argues that recent executive overreach and politicization have severely undermined established norms of U.S. civil-military relations. To restore professional standards, the incoming Congress must actively exercise its oversight powers, moving beyond mere criticism to demanding transparency in defense policy and personnel decisions. Key reforms include enforcing meritocratic promotion processes, requiring documented justification for senior officer removals, and preventing the partisan use of the military. These actions are crucial for bolstering public trust and ensuring the military remains a nonpartisan instrument of civilian control.

    The article argues that Donald Trump's unique and prolonged lame-duck period, coupled with domestic political pressures, makes him dangerously prone to international instability. Having exhausted major diplomatic gambits, Trump is expected to channel his energy into high-stakes, unilateral actions, primarily targeting adversaries such as Iran and Cuba. These potential actions—ranging from fresh strikes in the Persian Gulf to attempts at regime change—carry a significant risk of destabilizing regional security and triggering a global economic crisis. Policymakers must anticipate this pivot to high-risk foreign policy to mitigate potential international flare-ups.

    China's economic strategy is characterized by a persistent 'economics of denial,' prioritizing massive state-directed investment in advanced technology over addressing weak domestic consumption. This approach is rooted in a flawed belief that controlling physical capital will automatically generate productivity and wage growth, ignoring the structural imbalance where domestic demand consistently falls short of supply. This overinvestment and underconsumption model is unsustainable. Consequently, Beijing's policies will continue to generate global deflationary pressures and escalating trade friction, necessitating a fundamental pivot toward consumption-led growth for long-term stability.

    The Blue Wave signals significant voter frustration with cost of living and inflation, giving Congress a mandate to prioritize affordability and cost-reduction measures. Economically, the rapid build-out of AI data centers is creating localized stress, driving up skilled labor wages and straining resources, while also facing constraints from power grids and potential local regulatory backlash. Policymakers must manage this 'sequencing issue'—addressing rising costs before full productivity gains from AI can materialize—and anticipate shifts in global data center infrastructure as the market matures.

    The built environment workforce, comprising 15.3 million workers across 95 occupations, is foundational to modern infrastructure and economic stability. While highly paid, the workforce suffers from significant demographic imbalances, being disproportionately white and male, and often lacking clear career progression pathways. To prevent project delays and cost overruns, policy must mandate that capital asset owners treat labor market forecasting as core to project planning. Strategic interventions are required to strengthen career pipelines through robust apprenticeships, improve retention, and actively recruit younger and more diverse workers.
