Einführung
When you ask a property owner what moves an asset's value, ESG reporting rarely makes the shortlist. Rent, location, and the cost of capital get the attention, while sustainability data sits below them as a compliance task for later. Truth is, it should sit near the top.
For property owners, ESG reporting pays off in four ways. It supports higher asset value and rent premiums, keeps the portfolio ahead of regulation like CSRD, meets the requirements that investors and lenders now attach to capital, and turns operational data into lower running costs.
Wichtigste Erkenntnisse
- Umweltzertifizierte Büros erzielen einen Mietaufschlag – etwa 4 % in den USA und 4,9 % in Kontinentaleuropa –, und durch die ESG-Berichterstattung weisen die Eigentümer nach, dass sie die entsprechenden Kriterien erfüllen.
- Mit den Änderungen im Rahmen des EU-Omnibus-Pakets richtet sich die CSRD nun in erster Linie an Unternehmen mit mehr als 1.000 Beschäftigten, doch auch Eigentümer unterhalb dieser Schwelle erhalten weiterhin ESG-Datenanfragen entlang ihrer Wertschöpfungskette.
- Investoren und Kreditgeber betrachten ESG-Daten als Zugangsvoraussetzung, und GRESB ist der Maßstab, anhand dessen sie Immobilienportfolios vergleichen.
- ESG-Daten sind Betriebsdaten: Sie weisen rechtzeitig auf ausfallende Anlagen, den Betrieb außerhalb der Betriebszeiten und Leckagen hin, sodass diese behoben werden können, bevor sie sich auf die Bewertungen auswirken.
- Bei der Berichterstattung geht es nicht nur um CO₂ – soziale und Governance-Aspekte beeinflussen zunehmend die Art und Weise, wie Investoren und Mieter eine Immobilie bewerten.
Warum ESG-Berichterstattung für Immobilienbesitzer wichtig ist
ESG reporting matters because the people who decide what a building is worth now factor sustainability into that decision. Buyers, tenants, lenders, and regulators all read a building's energy and emissions record, and an asset that can produce clear, credible data is easier to sell, lease, finance, and insure than one that cannot.
The opposite case is just as real. Buildings that can't prove their performance tend to command lower rents, sit empty longer, and sell for less. Consistent reporting is what keeps an asset on the right side of that line.
The pressure has a clear source. Buildings account for 40% of the EU's energy consumption and 36% of its greenhouse gas emissions, which puts the real estate sector at the centre of the climate agenda. That is why the demand to measure and improve building performance keeps rising, and why ESG reporting has moved from a voluntary gesture to a core part of running commercial real estate.
Wie sich die ESG-Berichterstattung auf den Vermögenswert auswirkt
The clearest benefit is financial, because green certification carries a rent premium and reporting is what earns and sustains that certification.
When CBRE analysed roughly 20,600 U.S. office buildings, it found that LEED-certified assets commanded an average rent premium of about 4% between 2019 and 2022, sitting at the low end of a historical range that has run from 4% to 8%. The pattern holds in Europe, where CBRE reported a 4.9% rental premium for certified office assets in 2024, applying regardless of when the building was constructed.
Across a multi-building portfolio these percentages compound quickly through rent rolls and valuations, and ESG reporting is what allows an owner to see which assets already qualify for the premium and which need investment to reach it.
Green building certifications have gained significant traction as a way to protect that value, and the premium shows up across schemes. JLL research has found green rental premiums of up to 11.6% across global markets, with BREEAM among the certifications European owners use to earn it.
Was Immobilienbesitzer über die Einhaltung gesetzlicher Vorschriften wissen müssen
The regulatory picture shifted across 2025 and 2026. The EU's Stop-the-Clock directive first pushed several Corporate Sustainability Reporting Directive (CSRD) deadlines back. The follow-on Omnibus package – a set of EU reforms designed to simplify sustainability rules and ease the reporting burden on business, adopted in early 2026 – then narrowed who has to report at all. CSRD now applies mainly to companies with more than 1,000 employees and over €450 million in net turnover, which takes a large share of smaller entities out of the mandatory regime.
For owners, this leaves two consequences worth understanding. First, the largest portfolios and funds stay in scope, with second-wave reporting moving to financial year 2027 and third-wave to financial year 2028, so for most institutional players the obligation has been deferred rather than removed. Second, companies that now fall outside the mandate still receive ESG data requests from the larger partners in their value chain, and they remain affected by the EU Taxonomy and by the Sustainable Finance Disclosure Regulation (SFDR) requirements that reach them through their investors.
The underlying point is that the data requirement does not disappear when the mandate narrows. Our complete guide to CSRD compliance for real estate sets out where owners stand now and what to prepare.
Climate rules are tightening alongside the disclosure rules. The revised Energy Performance of Buildings Directive sets a path to a climate-neutral building stock by 2050, with all new buildings required to be zero-emission from 2030. For owners, that turns energy performance into a compliance question as much as an operating cost, and it rewards the renewable energy sources and efficiency upgrades that reporting helps prioritise.
Erwartungen von Investoren und Kreditgebern
Capital now treats ESG data as a condition of entry rather than a nice-to-have, and in real estate the reference point is GRESB.
The GRESB 2024 Real Estate Benchmark covered around USD 7 trillion in gross asset value across 15 sectors and 80 markets, and 65% of its participants had set net-zero targets. More than 150 institutional investors, with over USD 50 trillion in assets under management, use that data to monitor their holdings and compare managers against one another.
Lenders apply the same logic through green and sustainability-linked loans, which tie the cost of borrowing to disclosed performance, while the Task Force on Climate-related Financial Disclosures (TCFD) framework shapes much of what these investors expect to see.
For owners and asset managers, reporting consistently turns all of this from a compliance chore into a route to better financing terms and a wider pool of capital.
Was ESG-Daten über Ihr Portfolio aussagen
ESG data is operational data, and the figures gathered for a sustainability report also expose problems that would otherwise stay buried in monthly utility bills.
A spike in consumption often points to failing equipment, systems left running out of hours, or an undetected leak, and comparing similar buildings side by side shows which assets underperform and why. That visibility lets an owner direct maintenance spend to the buildings that actually need it, rather than spreading it evenly across the portfolio.
Erste Schritte mit der ESG-Berichterstattung
Getting started is more manageable than most owners expect, and a workable approach comes down to five steps.
- Legen Sie den Umfang fest. Entscheiden Sie, welche Vermögenswerte, Kennzahlen und Rahmenbedingungen für Ihr Portfolio und die Anleger, denen Sie Rechenschaft schuldig sind, relevant sind.
- Automatisieren Sie die Datenerfassung. Ersetzen Sie manuell erstellte Tabellen durch Messdaten und sensorbasierte Feeds, damit die zugrunde liegenden Daten konsistent und überprüfbar sind.
- Wählen Sie Ihre Rahmenwerke aus. Passen Sie Ihre Berichterstattung an GRESB, CSRD, TCFD oder die EU-Taxonomie an, je nachdem, an wen Sie berichten.
- Führen Sie Vergleichsanalysen durch und legen Sie Ziele fest. Vergleichen Sie Vermögenswerte untereinander und mit ähnlichen Objekten und legen Sie dann Reduktionsziele fest, deren Erreichung Sie tatsächlich nachverfolgen können.
- Bericht erstellen und handeln. Erstellen Sie den Bericht und nutzen Sie die darin enthaltenen Erkenntnisse als Orientierung für Ihre nächsten Investitionen.
Software handles most of the work across these steps. Our overview of the benefits of ESG reporting software for real estate goes into more depth, and owners without a dedicated sustainability lead can look at the ESG Officer role to understand what the function involves.

Häufig gestellte Fragen
Was versteht man unter ESG-Berichterstattung im Immobilienbereich?
ESG reporting in real estate is the structured measurement and disclosure of how a property performs on environmental, social, and governance criteria. It usually covers metrics such as energy use, greenhouse gas emissions, water, waste, and building certifications, gathered across a portfolio.
Müssen Immobilienbesitzer ESG-Daten melden?
It depends on size and structure. After the EU's 2025–2026 Omnibus changes, CSRD applies mainly to companies with more than 1,000 employees and over €450 million in net turnover. The largest owners and funds stay in scope; many smaller ones now sit outside the mandate but still field ESG data requests from investors, lenders, and larger partners in their value chain.
Was ist die GRESB-Bewertung?
GRESB is the leading ESG benchmark for real estate. Owners and funds submit annual data on management, performance, and development and receive a score that investors use to compare holdings. Its 2024 benchmark covered around USD 7 trillion in gross asset value.
Wie wirkt sich die ESG-Berichterstattung auf den Immobilienwert aus?
Reporting supports the certifications and performance records that carry rent premiums, which CBRE has measured at roughly 4% for LEED-certified U.S. offices and 4.9% for certified Continental European offices. It also helps owners avoid the discount that increasingly applies to assets that cannot prove how they perform.
Was bedeutet ESG im Immobilienbereich?
ESG in property means measuring and managing how a building performs across three areas: environmental, social, and governance. The environmental side covers energy use, carbon emissions, water, and waste. The social side covers tenant well-being, health, and community engagement. The governance side covers how the owner runs the asset, from data integrity to responsible business practices. For commercial real estate, ESG has become the language investors, tenants, and lenders use to judge quality.
Was ist das ESG-Rahmenwerk für Immobilien?
There is no single framework – owners usually report against several at once. GRESB is the leading benchmark for real estate portfolios, the Global Reporting Initiative (GRI) and the Task Force on Climate-related Financial Disclosures (TCFD) shape wider corporate disclosure, and the EU Taxonomy and CSRD set the regulatory baseline in Europe. Building certifications like LEED and BREEAM sit alongside these, validating performance at the individual asset level.
