Europe’s climate challenge is no longer defined by ambition. Targets are set, technologies exist, and further investment is underway. The real constraint is execution. How quickly can societies translate political goals into operational change across energy systems, buildings, industry, and public administration?
Across Europe, energy systems are becoming more complex, not less. Variable renewable generation, electrification of transport and heating, decentralised production, sector coupling, and rising demand for flexibility are all converging. Managing this complexity without high-quality, interoperable, and trusted data is impossible.
The International Energy Agency estimates that global electricity demand could grow by more than 25 per cent by 2030, mainly driven by electrification. At the same time, the European Commission projects that buildings alone account for around 40 per cent of energy consumption and 36 per cent of CO2 emissions in the EU. These are not problems that can be solved by infrastructure alone.
In short, we are trying to run a 21st-century energy system with 20th-century information flows.
Historically, climate policy has focused on physical assets such as wind turbines, grids, heat pumps, insulation, and industrial retrofits. These remain essential. But as systems scale, the marginal gains increasingly come from better use of what already exists.
Studies by the European Commission and the IEA consistently show that digitalisation and data integration can reduce energy system costs by 5–15 per cent, simply by enabling smarter operation, flexibility, and planning. In a fully electrified European energy system, that translates into tens of billions of euros annually. This makes data more than a supporting tool. It is core infrastructure.
Just as roads enable transport and grids enable electricity, data infrastructures enable climate action. They determine whether renewable energy can be absorbed efficiently, whether the flexibility market functions effectively, whether citizens can participate, and whether public authorities can act at the speed the climate science demands.
Denmark occupies a unique position in this transformation. For more than two decades, the country has invested in shared digital foundations: national registers, open data principles, digital identity, and interoperable systems. And the results are measurable.
Analyses of Denmark’s Basic Data Programme estimate around DKK 800 million (€107 million) in annual societal benefits, equivalent to DKK 8 billion over a decade. Opening address data alone generated €62 million in savings within four years. These gains were not theoretical as they came from reduced administrative costs, faster processes, and new digital services built on top of shared data.
The relevance for climate action is profound. Energy, buildings, water, transport, and land use all rely on the same underlying data assets. When these are accessible, standardised, and trusted, innovation accelerates across the entire ecosystem.
Denmark’s experience shows that digital readiness is not about having more data. It’s about having usable data that can be shared across sectors, reused safely, and combined in new ways.
Yet availability alone is not enough. Many countries now collect vast amounts of environmental and energy data. The bottleneck lies in activation.
Across Europe, public institutions still spend significant time manually processing applications, issuing permits, and meeting reporting obligations. Environmental impact assessments can take years. Energy efficiency programmes stall because approvals arrive too late. Citizens abandon green investments when processes become opaque, unpredictable or too demanding.
This is where data-driven automation changes the equation. When registers, maps, energy data, and administrative systems are connected, decisions that once took months can be made in minutes. The impact is not just bureaucratic efficiency; it is faster emissions reduction, increased democratisation, and greater shared responsibility for development.
Evidence from Danish programmes shows that automated case handling can fully process more than 60 per cent of applications instantly, freeing human resources for complex cases while accelerating climate-positive investments. In practical terms, that means installing heat pumps sooner, approving renewable projects faster, and implementing climate measures while political momentum remains.
Despite progress, Europe remains deeply fragmented. Electricity data is increasingly centralised, but heating, water, and building data are still scattered across hundreds of local utilities. Definitions differ across borders. Data quality varies. Access conditions are inconsistent.
This fragmentation has real costs. Companies operating across multiple countries must rebuild data pipelines market by market.. Municipalities struggle to benchmark performance. Policymakers lack comparable indicators. Innovation slows.
The European Union has recognised this risk. Initiatives such as European data spaces aim to create interoperable frameworks for sharing energy, mobility, and environmental data. But without decisive implementation, these risks become conceptual rather than operational.
Denmark’s experience suggests that progress requires three ingredients:
Without these, data remains locked in silos, and climate ambitions stall at the implementation phase.
