EU Allows Governments To Use Defence Fiscal Leeway For Green Energy Investment

EU governments may use up to 0.3% of GDP per year from existing defence fiscal flexibility for clean energy investments in 2026, 2027 or 2028.
The measure is capped at 0.6% of GDP over three years and applies to projects such as EV purchases, heat pumps, solar panels and batteries.
The Commission said the fiscal room cannot be used to subsidise fossil fuels, including petrol tax cuts.

EU Opens Fiscal Space For Clean Energy

The European Commission will allow EU governments to redirect part of their defence-related fiscal flexibility toward green energy investment, giving member states a limited new tool to reduce fossil fuel dependence as energy prices climb.

European Economic Commissioner Valdis Dombrovskis said governments may use a portion of the fiscal leeway already granted for higher defence spending to fund measures that support the shift away from oil and gas.

The decision follows pressure from Italy, where rising energy costs have become a political issue ahead of elections next year. Rome has pushed for softer fiscal treatment as households face higher bills linked to disruption in oil and gas flows through the Strait of Hormuz.

The Commission’s move offers a compromise. It keeps the EU’s broader fiscal framework intact, while giving governments some budget room for energy transition spending. It also draws a clear line between clean energy investment and fossil fuel subsidies.

A Narrow Opening Inside Defence Flexibility

Under normal EU fiscal rules, governments are expected to keep budget deficits below 3% of GDP. But Russia’s invasion of Ukraine changed the bloc’s spending priorities.

In March 2025, the Commission allowed every EU country to spend an extra 1.5% of GDP each year for four years on defence without breaching fiscal rules. That decision reflected growing concern over Russia’s security threat to Europe.

The new green energy allowance will sit inside that existing flexibility. Governments may use 0.3% of GDP per year in 2026, 2027 or 2028 for eligible clean energy measures. The total allowance cannot exceed 0.6% of GDP over the three-year period.

Dombrovskis said the funds could support the purchase of electric vehicles, the replacement of oil and gas heating systems with heat pumps, solar panel installation, and battery deployment.

The design is significant for finance ministries. It does not create a broad new spending exemption. Instead, it carves out a limited clean energy category within a defence-related fiscal tool.

Fossil Fuel Subsidies Are Excluded

The Commission has been urging governments to respond to higher energy prices by reducing consumption, not subsidising it. That position shaped the final compromise.

Italy had sought wider fiscal leeway to cushion voters from rising energy costs. It has also moved to cut excise tax on petrol. But the Commission said such measures will not qualify.

“Those kind of initiatives are not eligible,” Dombrovskis said of tax cuts.

That distinction matters for investors and energy companies. Brussels is making clear that fiscal support should accelerate demand for electrification, distributed energy, storage and efficiency. It should not extend the life of fossil fuel consumption through price relief.

Governments that use the extra fiscal space for green energy can deduct measures implemented since February, Dombrovskis said.

Italy’s Pressure Meets EU Security Politics

The policy reflects a widening tension inside the EU. Countries closer to Russia, including Finland, the Baltic states and Poland, have treated defence spending as an urgent national priority. Italy sees the Russian threat as more remote.

Rome has argued that higher energy prices pose a more immediate risk for households and voters. The Commission’s response gives Italy some political space, while preserving the core defence rationale behind the fiscal flexibility.

For countries such as Lithuania and Estonia, which have already used their full 1.5% of GDP allowance for defence investment, the Commission left another route open. They can still apply for the additional 0.3% of GDP for green energy measures. Approval would follow a debt sustainability analysis.

That approach helps avoid penalising member states that have moved fastest on defence. It also keeps fiscal discipline tied to debt risk.

What Executives And Investors Should Watch

For corporate leaders, the decision could create targeted demand across clean transport, heating, solar and storage markets. It may also strengthen national support schemes for households and companies, depending on how governments design their measures.

For investors, the key issue is implementation. The allowance is limited, but it gives member states a policy-backed channel to accelerate capital flows into technologies that reduce fossil fuel exposure.

The Commission is also reinforcing a broader governance message. Europe’s security, fiscal and climate agendas are now increasingly linked. Energy resilience is being treated not only as a climate target, but as a strategic priority.

The measure will not erase the pressure of high energy prices. Nor will it provide a large-scale fiscal reset. But it gives EU governments a defined path to respond without returning to fossil fuel subsidies.

For the bloc, the political stakes are clear. Europe is trying to protect consumers, fund defence and stay on course with its clean energy transition. The new fiscal compromise shows how difficult that balance has become.
