Europe’s building stock remains one of the largest barriers to the climate transition, accounting for approximately 40% of EU energy use and 36% of greenhouse gas emissions. While the need for deep retrofits is clear, scaling them remains challenging due to fragmented ownership structures, financing constraints, and the high costs of monitoring and verification.
Within the EU-funded ARV project, the City of Palma de Mallorca is piloting district-scale retrofitting in low-income multifamily neighbourhoods through a public-private partnership model. The initiative is exploring how innovative climate finance mechanisms can help unlock retrofit projects that may otherwise struggle to secure funding.
The challenge is bigger than carbon accounting
Early feasibility work investigated whether retrofit-linked carbon credits could provide additional financial support for deep retrofits. While the analysis demonstrated strong alignment with existing carbon accounting methodologies, it also highlighted a fundamental issue: the challenge is not simply measuring emissions reductions, but creating the infrastructure needed to support retrofit finance at scale.
High verification costs, fragmented data collection, administrative complexity, and long delays between retrofit delivery and revenue generation can significantly reduce the viability of retrofit-linked carbon projects, particularly in multifamily housing environments.
Data infrastructure as a climate finance enabler
As buildings become increasingly connected, smart meters and digital energy systems are creating new opportunities to measure performance continuously rather than relying on periodic, manual verification processes.
This shift has the potential to transform retrofit finance by reducing operational costs, improving transparency, and strengthening confidence in measured climate outcomes.
Unlocking this opportunity requires trusted digital infrastructure capable of connecting building performance data, verification processes, and climate finance mechanisms into a scalable system.
Building the infrastructure for scalable retrofit finance
As part of the ARV ecosystem, BEClimate, through its BEVerify infrastructure, is supporting the development of a measurement-first approach to retrofit-linked climate finance.
By leveraging continuously monitored operational energy data and digital MRV (Monitoring, Reporting and Verification), BEVerify is designed to reduce verification friction, improve transparency, and enable a stronger link between capital deployment and real-world emissions reductions.
This is about more than carbon credits. It is about creating the operational infrastructure required to make retrofit finance more efficient, scalable, and investable.
A collaborative pilot with European ambitions
The Palma pilot brings together municipalities, researchers, retrofit delivery partners, climate finance specialists, and technology providers, including the City of Palma de Mallorca, Green Digital Finance Alliance (GDFA), IREC, and BEClimate.
Together, the project is testing whether district-scale coordination combined with digitally enabled verification can support a more practical and scalable model for financing building decarbonisation.
Looking ahead
While still in its early stages, the pilot offers valuable insights into how retrofit finance could evolve across Europe.
The findings suggest that scaling building decarbonisation will require more than funding and policy support. It will also depend on the development of trusted digital infrastructure that makes climate outcomes continuously measurable, verifiable, and financeable.For BEClimate, this represents a significant opportunity: helping build the infrastructure layer that can connect retrofit activity, building performance data, and climate finance into a scalable model capable of supporting Europe’s transition to a lower-carbon built environment.
