The European Union will import over 98% of its natural gas by 2050 unless it invests in new domestic field development, according to research released September 14 by Wood Mackenzie. The consultancy modeled three production scenarios through mid-century and found the gap between minimal action and maximum development equals roughly three years of the bloc's current gas consumption. Policy and investment choices made over the next five years will determine whether Europe locks in near-total dependence on foreign suppliers or carves out meaningful domestic production.
The EU currently imports 85% of the gas it uses, a figure that holds steady into the early 2030s. But as Norwegian output begins declining from its peak in that decade, North African supplies face pressure from rising domestic demand, and Russian pipeline deliveries phase out entirely, liquefied natural gas is stepping in to fill the shortfall. LNG's share of EU supply could climb from around 40% today to 63% by 2050, with the United States providing 77% of those volumes. Wood Mackenzie's low-case scenario assumes no new field investment: production would drop from 43 billion cubic meters in 2028 to just 2 bcm by 2050, with LNG covering the difference. The mid-case projection, reflecting current policy and spending levels, holds output near 40 bcm until 2038, delivering 330 bcm cumulatively—70% more than the low case—yet domestic gas never supplies more than 17% of demand across the timeframe. The high case, by contrast, reaches 77 bcm by 2042, meeting 38% of demand and delivering 1,400 bcm cumulatively, which would displace the equivalent of 615 LNG cargoes annually compared to the low scenario. Exploration accounts for 680 bcm of the nearly 1,000 bcm difference between the low and high cases, with 70% of that undiscovered volume concentrated in the Black Sea and East Mediterranean. Greece alone holds a third of the yet-to-find potential, as Energean and ExxonMobil prepare to drill the country's first deepwater exploration well in 2027. Cyprus, modeled separately, could add up to 340 bcm of re-import potential via Egypt, though the report notes not all of that volume is expected to reach European markets.
"The mid case is often where expectations settle, but it changes very little for the EU's strategic position," said Lewis Lawrence, senior research analyst for Europe upstream at Wood Mackenzie. "Sustaining today's output requires enormous investment just to stand still. The real question is whether governments are willing to create the conditions that make the high case possible, because the window is narrowing." The report notes that maintaining even the mid-case plateau demands replacing more than half the current producing base, leaving the EU's exposure to global markets largely unchanged. On cost, the analysis finds US LNG delivered to northwest Europe breaks even 68% above gas from Romania's Neptun Deep field and 96% above new Norwegian supply, while domestic gas carries a fraction of the emissions intensity of imported LNG—in the Netherlands, LNG provides 50% of gas supply but accounts for 88% of overall supply emissions.
The high case depends on three conditions coming together: fiscal terms need to stabilize, permitting processes must accelerate, and corporate constraints have to be resolved. European tax regimes are competitive on paper but have been repeatedly undermined by instability—the EU's temporary solidarity contribution, introduced in 2022, remains under legal challenge today. Policy across the bloc diverges sharply: nations around the East Mediterranean and Black Sea are actively courting explorers, while Denmark, France, and Spain have legislated end dates for production and closed the door to new licenses. Domestic gas won't make the EU self-sufficient, the report concludes, but stable fiscal frameworks and successful frontier exploration could meaningfully cut LNG reliance. Without that, the bloc is set to become almost entirely dependent on international markets within a generation.
