Most new U.S. gas pipelines set to serve LNG exports, report says

(UI) — A new report by the Center for Energy & Environmental Analysis (CEEA) highlights a dramatic surge in U.S. natural gas pipeline construction, with more than 100 projects either planned or under development.

The report finds that the vast majority of this infrastructure—roughly 80% of active pipeline capacity—is intended to support liquefied natural gas (LNG) exports, not U.S. energy independence.

According to the data, 104 natural gas transmission pipeline projects are in the works, totaling 99 billion cubic feet per day (Bcf/d) in potential new capacity. That figure nearly matches the total U.S. gas production in 2024, estimated at 103 Bcf/d. Of the 99 Bcf/d, about 67 Bcf/d is expected to be added between 2025 and 2027—more than double the capacity added in the last three years.

CEEA's analysis shows that nine of the ten largest projects in development run through Texas and Louisiana, positioning them to feed LNG export terminals located in those states. These projects are driving what the report describes as a “tidal wave” of capacity intended for international markets—particularly in Asia and Europe—rather than meeting domestic heating, manufacturing, or power generation needs.

The report argues this export-driven buildout could raise natural gas prices for U.S. consumers and businesses while locking in long-term fossil fuel emissions, particularly from methane leaks and flaring. Although only a small percentage of methane emissions occur during transmission, the report warns that pipeline expansions will increase upstream production, where the bulk of methane leakage happens.

Communities along the Gulf Coast—especially in Louisiana and Texas—are expected to bear the brunt of this buildout, with added emissions from construction, flaring, and operations compounding existing environmental and public health concerns. CEEA cites studies showing these areas are already overburdened by petrochemical infrastructure and pollution.

The report also flags concern that such large-scale buildouts are incompatible with U.S. climate goals and net-zero pledges. Despite permitting challenges and market uncertainty, the current regulatory environment could accelerate pipeline approvals, especially under deregulatory policies.
