European technology executives warned on Friday that surging AI investment and ambitious net zero pledges risk stalling unless companies sharpen their focus on implementation, governance, and measurable outcomes. Their concerns come as European private equity and venture capital firms poured $6.8 billion into AI companies in 2025, an 83% year-on-year jump, yet only 18% of banks have embedded generative AI into daily operations, according to Personetics research.
The disconnect between funding and deployment mirrors the early days of cloud computing, said Theo Wasserberg, Head of UK and Ireland at treasury platform Embat. Many pilots failed to deliver systemic change because they lacked the infrastructure and trust needed to scale.
"AI adoption shouldn't be a cosmetic upgrade on top of legacy systems. AI delivers value only when it's tightly scoped, with defined users, datasets and measurable outcomes. This is what I call contained value: specific, auditable use cases where you know what AI will do, who it serves and how success will be measured," Wasserberg said.
Wasserberg's emphasis on contained value and moving from demos to daily tools aligns with the practical guidance found in AI for Executives & Strategy, where implementation and governance challenges take centre stage.
Enterprise leaders are also grappling with geopolitical risks. Kurt Muemehl, Head of AI Strategy at Dataiku, said potential US government stakes in major model providers raise strategic questions for European firms.
"The news that the US government could take a stake in OpenAI, and that other models could follow suit, is a wake-up call for Europe on two fronts: dependence on foreign-owned AI and the risk of critical AI capabilities becoming increasingly controlled by powers on another continent," Muemehl said. He urged executives to assess whether their core AI assets-agents, workflows, data, and governance-remain under their control and to prepare backup models that can be deployed if primary systems are cut off.
Cost visibility and infrastructure constraints
Cost predictability is emerging as another brake on AI returns. Kevin Dunn, Vice President and General Manager, EMEA at cloud storage firm Wasabi, said organisations now allocate around 62% of their AI budgets to data, storage, and compute, yet only 25% report a positive return.
"As AI adoption accelerates, the real constraint is visibility and control over what it actually costs to innovate at scale. When a significant share of spending is driven by variable fees rather than predictable capacity, organisations lose the ability to forecast and optimise AI economics with confidence," Dunn said.
Trust and the verification gap
Trust in AI output remains a recurring concern. Evan Reiss, Senior Vice President of Marketing and Innovation at PDF software provider Foxit, said verification work is eroding productivity gains. Executives save an average of 4.6 hours a week using AI but spend nearly the same amount of time checking its work.
"Without confidence in the output, productivity gains quickly disappear. The burden is now on technology companies to help close this trust gap. The conversation needs to move beyond AI adoption and towards AI confidence," Reiss said.
Luis Blando, Chief Product & Technology Officer at OutSystems, said most enterprises are pursuing pragmatic deployments rather than full autonomy. The strongest use cases cluster around document processing, high-volume transactional work, and decision support where AI summarises complexity and offers recommendations but does not make final calls.
"Trust doesn't come from autonomy alone. It comes from knowing when AI should assist, when humans should decide, and how the two work together," Blando said.
Net zero strategies face lifecycle scrutiny
Alongside AI, European executives are reassessing climate strategies in the electronics sector. Arjen Steenbergen, ESG Manager at peripherals maker Trust International, said emissions reduction must start in design and manufacturing, not just at end of life.
"More than 80% of a headset's climate footprint is generated during manufacturing, while global e-waste is expected to exceed 80 million tonnes by 2030. Together, these figures show why reducing environmental impact has to begin long before a product reaches consumers, through better design and more responsible manufacturing," Steenbergen said.
Why this matters for executives and strategy
The warnings from European technology leaders point to a common thread: without disciplined implementation, clear governance, and measurable outcomes, both AI and net zero investments risk becoming expensive experiments. Executives must demand contained value-tightly scoped use cases with defined users and auditable metrics-while also stress-testing their AI supply chains for geopolitical dependency. Trust in AI systems won't come from more models, but from verification processes that let teams act on insights without second-guessing every output. In sustainability, the same rigour applies: progress will be judged on proven reductions across the full product lifecycle, not on announced targets.
