Europe has made dramatic progress in reducing its dependence on Russian energy since Russia’s full-scale invasion of Ukraine in 2022.

What was once a relationship supplying around 45% of the EU’s gas imports has shrunk to about 12% in 2025, with remaining volumes around 35-38 billion cubic meters (bcm) annually.

A landmark REPowerEU regulation (EU/261/2026), adopted in early 2026 following a December 2025 political agreement, formalizes a gradual but permanent phase-out: Russian LNG imports are set to end by early 2027, with pipeline gas following by late 2027 (full application by November 2027 in some timelines).

This “divorce” ends billions in annual payments to Russia (around €10 billion yearly for the remaining gas) while accelerating diversification. It also spotlights the successes, challenges, and future of alternative pipeline infrastructure built or expanded precisely to reduce reliance on Moscow.

Since the 2022 REPowerEU Plan, the EU has banned Russian coal imports entirely, slashed oil imports from 27% to about 2%, and dramatically cut gas dependence through a mix of LNG imports (especially from the US, Qatar, and others), renewables acceleration, energy efficiency, and new supply routes.

National diversification plans were due by March 2026, with prior authorization requirements for non-exempt imports and robust monitoring/penalties to prevent circumvention.

Exempt countries for prior authorization (those supplying >5 bcm in 2024 with sanctions or limited infrastructure) include major alternatives like Norway, the US, Qatar, Algeria, Nigeria, and the UK.

Legal challenges persist, such as Nord Stream 2 AG’s June 2026 lawsuit alleging de facto expropriation by the ban. The phase-out has already shifted flows: TurkStream remains a key (but limited) route post-Ukraine transit end, while LNG has surged as a bridge.

The phase-out has accelerated a multi-pronged strategy of demand reduction, renewables acceleration, and supply diversification—particularly through LNG terminals and non-Russian pipeline routes.

EU’s strategy has enabled the bloc to rapidly expand LNG import capacity (up ~31% in recent years), with floating storage and regasification units (FSRUs) and new onshore terminals playing a key role in replacing lost Russian volumes.

The Russian phase-out has also validated and accelerated non-Russian pipeline projects, particularly the Southern Gas Corridor (SGC), a flagship diversification effort and the Baltic Pipeline.

These projects, many conceived or accelerated under REPowerEU and earlier diversification efforts, demonstrate how ending Russian dependence has catalyzed tangible infrastructure investment. The EU has also pursued hydrogen-readiness in some pipelines, aligning with longer-term decarbonization goals.

Other routes and projects have gained prominence:

These projects underscore a strategic pivot: from single-supplier dependence (especially direct Russian pipelines like the damaged Nord Streams) to diversified, resilient routes emphasizing the Caspian, North Africa, North Sea, and global LNG.

While the EU is working to wean off russian energy supplies, success is not guaranteed. Remaining Russian imports (via legacy contracts and TurkStream) require careful management, and some member states (e.g., Hungary, Slovakia) face higher transition hurdles.

Global LNG markets also must accommodate Europe’s needs amid competition, and prices remain elevated compared to pre-2022 levels.

Pipeline projects face their own issues: high costs, permitting, environmental concerns, and geopolitics (e.g., EastMed).

Azerbaijan’s ability to scale to 20 bcm/year depends on field development, demand commitments, and infrastructure upgrades. Broader EU goals include renewables and efficiency to reduce overall gas demand.

The Russian gas phase-out is a geopolitical and energy security success story. It has not only curtailed funding for aggression but catalyzed investment in alternatives like the SGC/TAP expansions, proving Europe can build resilient supply networks.

As the 2027 deadlines approach, sustained focus on diversification, interconnectors, and the green transition will determine long-term success. The “divorce” is painful but necessary—and it is reshaping Europe’s energy map for decades.
