Germany has implemented EU Taxonomy sustainable finance requirements with a rigour that exceeds the regulatory minimum in several respects, reflecting a broader German institutional culture around ESG compliance that is generally stricter than what other EU member states apply in practice. German institutional investors and their asset managers extending this discipline to real estate holdings outside the EU, including in Türkiye, face a genuine question: how do you apply Taxonomy-aligned rigour to a market where the underlying certification infrastructure looks different from Germany's own.
The limits of standard certifications
LEED and BREEAM, the most widely used international sustainability certifications, measure a building's operational performance, energy efficiency, water use, indoor air quality, while it is occupied. This is valuable but incomplete, particularly against EU Taxonomy criteria, which increasingly expect consideration of a building's full lifecycle impact, including what happens to its materials at end of life. A German institutional investor relying solely on an operational certification for a Turkish asset is working with a genuine gap relative to their domestic Taxonomy compliance standard.
A more complete framework
The Circular Development Score, a measurement tool developed specifically to evaluate real estate across its full lifecycle rather than only its operational phase, scores a project on material recoverability, design adaptability, supply chain circularity, energy and carbon circularity, and documentation quality. This kind of framework maps more directly onto the lifecycle-thinking that EU Taxonomy criteria increasingly expect, giving German investors a way to evaluate a Turkish asset against a standard closer to what their own domestic reporting requires, rather than a lower bar calibrated to a market with less developed sustainability infrastructure.
Why this matters practically, not just for compliance optics
German institutional investors should treat this as more than a reporting exercise. A Turkish development that scores poorly on material recoverability and design adaptability carries genuine long-term obsolescence risk, structures that cannot be disassembled or repurposed face demolition as the only realistic end-of-life outcome, which affects both the asset's terminal value and its ongoing defensibility as institutional-grade capital. Circular performance and financial performance are connected, not separate reporting exercises layered on top of an otherwise unrelated investment decision.
What to ask a Turkish developer
German investors evaluating a specific Turkish opportunity should move beyond a developer's general sustainability marketing language and ask specific, documentable questions: is there a material passport or digital as-built record? What proportion of structural materials can be recovered or reused at end of life, given the structural system chosen? What proportion of materials used carry recycled content or a viable secondary market? These questions produce answers that can actually be verified and reported, rather than a general sustainability narrative that does not survive scrutiny from a German compliance team.
Where Türkiye's industrial base helps
Türkiye's manufacturing capacity in steel, ceramics, and prefabricated concrete gives it a genuine, underlying capability to support circular material flows that not every emerging real estate market can match, provided a specific development has actually been designed with that potential in mind from the outset rather than retrofitted as a marketing claim after the fact.
A grounded next step
For German institutional investors and their asset managers, the most useful next step when evaluating Turkish real estate against Taxonomy-aligned criteria is engaging an advisor who can apply a genuine full-lifecycle circular assessment to a specific opportunity, rather than accepting a standard operational certification as sufficient evidence of the sustainability performance German reporting requirements increasingly expect.
