Executive summary
The Union enters the next institutional cycle facing three objectives that are often presented as competing: the climate transition, industrial competitiveness, and security and defence. This booklet argues that, framed correctly, the three are largely complementary, and that the binding constraint is investment and its financing rather than any inherent trade-off between the goals. It sets out the scale of the financing challenge (Section 2), the principal policy levers available (Section 3), and supporting detail in the annexes.
Section 1 — Context and objectives
Article 3 of the Treaty on European Union commits the Union to sustainable development, a highly competitive social market economy, and the security of its citizens. In the current geopolitical environment these objectives have moved to the centre of the political agenda simultaneously. The war on the Union's borders, dependence on imported energy and critical inputs, and intensifying global competition in clean and advanced technologies mean that climate, competitiveness and security can no longer be pursued in separate policy silos.
The central question for the next cycle is therefore not which objective to prioritise, but how to sequence and finance moves that serve all three at once.
Section 2 — The investment challenge
2.1 The financing gap
Recent competitiveness analysis estimates an additional investment need of the order of €800 billion per year to keep pace with global competitors and meet the Union's stated objectives. Crucially, this gap is concentrated in three areas — advanced technologies, energy infrastructure and defence — which are precisely the areas where the climate, competitiveness and security objectives overlap. Investment directed at these areas therefore advances all three goals simultaneously rather than trading one off against another.
2.2 Why public budgets alone cannot close it
The scale of the gap is far beyond what national budgets and the Union budget can finance directly, particularly given post-pandemic debt levels and fiscal rules. The implication is that the bulk of the additional investment must be mobilised from private capital, with public funds used to de-risk and crowd in private finance rather than to substitute for it.
Section 3 — Policy levers for the next cycle
Three concurrent levers are available. They are complementary and, taken together, address both the supply of finance and the conditions for productive investment.
- Deepen the single market for capital to unlock private savings (see Annex II).
- Simplify targeted state aid for strategic sectors while protecting the level playing field (see Annex III).
- Align the next multiannual budget with strategic priorities and strengthen own resources (see Annex III).
Annex I — Treaty basis and timeline
| Milestone | Indicative timing |
|---|---|
| Competitiveness and prosperity agenda adopted | Start of the cycle |
| Capital Markets Union relaunch package | 2026 Commission priority |
| Clean Industrial Deal state-aid framework | Under implementation |
| Negotiations on the next multiannual financial framework (MFF) | Across the cycle |
Annex II — Capital Markets Union
The Capital Markets Union (CMU) is identified as the largest unused lever for mobilising private investment at scale. The booklet confirms it as a Commission priority for 2026. Two blockages are singled out as central:
- Retail-investor participation — European households hold a large share of savings in low-yield deposits; channelling part of this into productive investment would provide a deep, stable domestic funding base.
- Harmonised prospectus rules — fragmented issuance requirements raise the cost of raising capital across borders; harmonisation would lower barriers for companies financing the climate and security transitions.
Movement on the CMU finances the transitions without new taxpayer contributions, which is why it is treated as the first-order move.
Annex III — State aid and the Union budget
Two further, complementary moves complete the package.
- Targeted state-aid simplification for strategic sectors, building on the Clean Industrial Deal, to accelerate investment in clean and advanced manufacturing while preserving the integrity of the single market.
- Alignment of the next MFF with strategic priorities, including new own resources tied to Emissions Trading System (ETS) revenue and the Carbon Border Adjustment Mechanism (CBAM), which are identified as politically feasible sources of financing that also reinforce the climate objective.
Annex IV — Guidance to the reader
Candidates should treat the figures and references above as the evidentiary basis for their response. A strong answer will draw specific material from this booklet — for example the €800 billion figure in Section 2.1, the CMU blockages in Annex II, and the own-resources proposal in Annex III — rather than relying on general knowledge alone.
