本論文は、128のシナリオを用いて、世界の気候変動対策や米国内の政策がLNG輸出に与える影響を分析。2050年の輸出量がシナリオ間で4倍も異なること、国内消費と輸出の戦略的競合が重要であることを示す。CART分析により、要因は多様で単一の支配的要因はないと結論。
English
This paper uses 128 scenarios to explore how global climate ambition and US domestic policies affect US LNG exports. It finds a four-fold variation in 2050 exports, highlighting strategic competition between domestic gas retention and LNG export. A CART analysis shows no single driver dominates, emphasizing the role of policy, technology, and market uncertainties.

📄 Abstract（原文）
Abstract Liquefied natural gas (LNG) has rapidly become a critical commodity on the global energy market. While the United States is now the world's largest exporter of LNG, there is ongoing debate over whether LNG exports align with US long-term climate and economic goals, especially given increasing trade uncertainty in global LNG markets. To inform this debate, we explore how various combinations of global market conditions and domestic policy choices influence the timing and magnitude of U.S. LNG exports. A set of 128 scenarios is systematically constructed by varying four global drivers (climate ambition, socioeconomic development trajectories, upstream gas production cost, and cost of carbon capture and storage technologies) and three domestic drivers (U.S. climate target, gas infrastructure cost, and LNG trade strategy). Simulating these scenarios with the Global Change Analysis Model (GCAM), we find that U.S. LNG exports in 2050 vary by a factor of four across these scenarios, which is a substantially larger variation than that of global gas demand or global LNG trade. Notably, the variation in U.S. LNG export across scenarios exceeds the variation in domestic gas production, highlighting the strategic competition between retaining domestically produced gas for U.S. consumers and exporting it to the global market as LNG . Based on a Classification and Regression Tree (CART) analysis to evaluate the relative importance of these drivers, we find that while U.S. LNG trade strategy and global climate ambition are the two most influential, no single factor dominates. This result suggests that U.S. LNG export trajectories are jointly shaped by domestic and global drivers, underscoring the importance of policy, technological, and market uncertainties in guiding energy investments.
