Louisiana LNG – A new Woodside LNG terminal near Lake Charles is projected to emit more greenhouse gases than any existing or recent US LNG export facility—raising fresh questions about “clean” gas claims as Louisiana faces intensifying climate risks.
Louisiana’s LNG boom has long been sold as a climate-friendly bridge fuel—cleaner than coal, reliable for energy markets, and preferable for countries trying to cut emissions.
But a major expansion under construction near Lake Charles is set to challenge that narrative.. The Louisiana LNG terminal. owned by Woodside Energy. is projected to produce substantially more greenhouse-gas pollution than every LNG export terminal built in the United States so far. according to analyses of state and federal records reviewed for Misryoum.
Why “clean gas” claims are colliding with Louisiana’s emissions math
Since Louisiana launched the US liquefied natural gas export rush in 2016. LNG has been promoted as a less climate-damaging alternative to coal and oil.. Sabine Pass LNG. the state’s first export facility. became one of Louisiana’s largest sources of climate-warming pollution—releasing more greenhouse gases than the state’s biggest oil refineries.
Now, the bigger threat is taking shape.. Louisiana LNG, expected to open in 2029, would add emissions from the liquefaction process and other energy-intensive operations.. Permitting documents filed with Louisiana regulators project annual greenhouse-gas output above 9.5 million tons of carbon dioxide equivalent—far higher than Sabine Pass. and higher than the emissions estimates for other LNG terminals built over the past decade.
The Lake Charles terminal’s scale could reshape the Gulf Coast’s climate footprint
The project’s planned size and emissions profile matter in part because LNG isn’t just “natural gas in a different container.” Liquefaction requires major energy input to cool gas to a liquid state. and the chain doesn’t stop at the factory gate.. Storage, shipping, and eventual re-gasification all factor into an LNG footprint that can be larger than many public comparisons assume.
Misryoum’s review of the project’s permitting and emissions framing places Louisiana LNG among the most significant greenhouse-gas sources in the state.. In relative terms. its estimated emissions would rank just below the CF Industries chemical complex in Donaldsonville—home to massive industrial chemistry that already drives heavy climate pollution.. That comparison is stark: it suggests the new LNG facility isn’t simply another energy infrastructure project. but a potentially top-tier contributor to Louisiana’s overall greenhouse-gas load.
Woodside acquired the 1. 000-acre site near Lake Charles in 2024 from Tellurian. which had been developing the facility under the name Driftwood LNG.. The company is putting forward a facility expected to require nearly $18 billion in construction. putting it among the largest foreign investments in Louisiana’s history.
Local jobs and tax revenue—plus a harder question: what counts as “progress”
Proponents of LNG expansion often emphasize jobs, local investment, and the economic momentum that follows large industrial construction.. Louisiana’s economic development messaging around the project points to thousands of temporary construction jobs and hundreds of permanent roles once operations begin. along with increased local tax revenue.
Environmental groups and many residents see a different side of the ledger—one tied to the lived experience of repeated storms and rising seas.. Anne Rolfes. executive director of the Louisiana Bucket Brigade. described the scale of the projected emissions as “distressing. ” arguing that adding greenhouse gases deepens Louisiana’s vulnerability to climate threats that are already unfolding.. In her view. the logic is blunt: as Louisiana becomes more exposed. building more pollution intensifies the risk rather than reducing it.
That tension—between near-term economic gain and long-term climate harm—is where Misryoum sees the central policy conflict.. LNG infrastructure is built to last for decades.. Climate impacts and extreme-weather stress are also long-lived.. The mismatch is what makes a “next decade” emissions estimate feel immediate to people living in southwest Louisiana.
Woodside says it will reduce emissions—but the scale is the problem
Woodside has said its priority is to avoid and reduce emissions.. In company messaging provided to Misryoum. the firm describes decarbonization plans intended to identify technical opportunities to reduce pollution at the facility. along with a broader corporate climate strategy aimed at cutting greenhouse-gas emissions by 30% by 2030 and reaching net-zero by 2050.
Woodside also points to incremental climate measures it has made in recent years, including improvements intended to reduce methane leakage. The company has also referenced the use of carbon credits in its climate reporting, including investments in forest restoration to offset impacts.
Yet even if those steps help manage emissions at the margins. the projected headline numbers reflect a scale that’s hard to “fix” through incremental adjustments alone.. When a facility is expected to emit more than the existing US LNG fleet’s recent additions—on top of what’s already happening at Sabine Pass—the core question becomes whether reductions within the project meaningfully counterbalance the emissions created by expanding LNG output.
A global energy story is also a local climate story
LNG has benefited from geopolitics as well as economics.. The Russia-Ukraine war helped shift European demand toward LNG. with US cargoes filling part of the gap created by reduced pipeline supply.. That demand pull has supported the idea that LNG can stabilize energy security—especially for countries still working through the transition away from coal.
But the same dynamics can increase the climate stakes.. If LNG supplies relieve immediate energy shortages. they can also lock in additional fossil fuel infrastructure and sustain fossil fuel use longer than some climate pathways would require.. Misryoum’s analysis of the broader US build-out suggests that while LNG is presented as a transition tool. the infrastructure pipeline largely concentrates on the Gulf Coast. including multiple sites in Louisiana.
The result is a double exposure: local communities near LNG terminals face the environmental and climate risks from new emissions, while national and international markets continue to treat LNG as a bridge—sometimes indefinitely.
What comes next: permitting speed, public debate, and the emissions ceiling
Policy direction has accelerated LNG development in recent years. A pause on permitting introduced earlier was later reversed, allowing new projects to move forward. Multiple regulatory barriers that normally slow LNG timelines were rolled back, enabling a faster build-out.
For Louisiana residents. the pace can feel like a tradeoff: decisions about infrastructure are made quickly. while climate consequences arrive over decades and intensify with each additional ton of greenhouse gas.. For Misryoum. the critical turning point is not only whether a company can reduce emissions within its own operations. but whether the overall trajectory of LNG expansion aligns with climate-risk realities for states like Louisiana.
Louisiana LNG is expected to open in 2029. By then, the debate sparked by its projected emissions will likely have widened beyond one terminal—shifting from whether LNG is “cleaner” than coal to whether expanding LNG itself is consistent with preventing the worst climate outcomes.
If Louisiana’s LNG growth continues at this scale, the question facing the state may become less about the promises made at groundbreaking ceremonies and more about the measurable emissions ceiling—especially as the Gulf Coast confronts storms that do not wait for policy timelines.
