Green finance approach

PSP Swiss Property pursues a consistent and ambitious sustainable financing strategy: All our financing instruments are directly linked to sustainability criteria. We have reclassified all our bonds as Green Bonds and converted all our credit facilities into Sustainability-Linked Loans (SLLs). As a result, 100% of our interest-bearing debt is tied to the sustainability goals of our property portfolio.


The Green Finance approach emphasises the importance of sustainability as an integral part of our strategy by linking our debt financing with the sustainability strategy and, in particular, our commitment to reduce CO2 emissions

Green Asset Portfolio

Our basis for green financing

The Green Asset Portfolio is the basis for the Green Bond Framework and the green loans.

The inclusion of a property is based on two criteria, which must be met simultaneously: the effective CO2 emissions per square meter and a property-specific sustainability rating. The core of this framework is the ongoing improvement of CO2 emissions. The current limit for inclusion of investment properties is 12 kg CO2 per square meter. The sustainability rating is determined by the independent company Wüest Partner. The Green Asset Portfolio is generally revised once a year.

RE ESG Plus rating

Working tool and qualification criterion

The property-specific and GRESB-recognised RE ESG Plus rating by Wüest Partner pursues a holistic approach that integrates various aspects in the environment, social and governance categories.

Further information can be found on the Wüest Partner website:

Percentage distribution of the RE ESG Plus rating 2024

The maximum score is 5. To qualify for the Green Asset Portfolio, a score of at least 3.5 is required in addition to a CO2 intensity of less than 12 kg/m2.
