Gas in Mexico: Risks and Alternatives for a Sustainable Energy Model

Key Takeaways

• Over 70% of Mexico's gas imports come from the U.S.
• Reliance creates vulnerability to supply shocks and price spikes.
• Assumptions of cheap, stable gas conflict with climate goals.
• Methane emissions risk undermining Mexico's net-zero commitments.
• Policy roadmap calls for risk assessment, demand management, renewables.

Summary

Mexico relies on imported natural gas for more than 70% of its consumption, chiefly via pipelines from Texas. This dependence underpins electricity generation, industrial processes and Pemex operations, but it also exposes the country to supply disruptions, price volatility and heightened methane emissions. The discussion paper challenges three long‑standing policy assumptions—steady supply, low U.S. prices and negligible climate impact—arguing they no longer hold in a volatile geopolitical climate. It proposes a risk‑based framework, demand‑management policies and stronger methane monitoring to align gas use with Mexico’s energy transition goals.

Pulse Analysis

Mexico’s gas import structure is a double‑edged sword. While natural gas fuels the bulk of the nation’s power plants and supports key industrial sectors, the over‑reliance on cross‑border pipelines ties Mexico’s energy stability to U.S. market dynamics and diplomatic relations. Analysts note that the current infrastructure, built around a single supply corridor, limits diversification and amplifies the impact of any disruption, whether from geopolitical tension, pipeline maintenance, or sudden shifts in U.S. production policy.

Beyond supply concerns, the economic and environmental dimensions are equally pressing. Price volatility in the U.S. Henry Hub can quickly translate into higher electricity tariffs and industrial costs, eroding competitiveness. Moreover, imported gas carries a hidden climate penalty: methane leakage across the supply chain undermines Mexico’s net‑zero targets and could attract regulatory penalties under emerging international standards. The risk of stranded assets also looms, as global capital increasingly favors renewable projects, potentially leaving gas‑heavy investments underutilized.

The paper’s policy roadmap offers a pragmatic path forward. By instituting a comprehensive risk‑assessment framework, Mexico can quantify exposure and prioritize mitigation measures. Demand‑side management—through efficiency standards and flexible pricing—can curb unnecessary consumption, while a coordinated push for renewable integration reduces the baseline need for gas. Strengthening methane measurement, reporting and verification (MRV) will not only improve transparency but also position Mexico to meet future carbon‑pricing mechanisms. Leveraging existing legal and institutional capacities, the country can gradually decouple from imported gas, securing a more resilient, affordable and climate‑aligned energy future.
