Sustainability strategy

To achieve our goals, we consistently follow our sustainability strategy. 


GRI 2-12, 2-29, 2-30

Sustainability is a shared goal. We therefore foster regular communication with our stakeholders and include their concerns and needs in both our business strategy and our everyday decisions. This communication plays an essential role in constantly improving how we deal with these issues as well as in addressing today’s needs and those of tomorrow with new solutions.

At the same time, we would like to make our stakeholders aware of vital social and environmental issues through our actions and decisions and, by doing so, also influence their own actions and deci-sions. To find out whom we view as our stakeholders, what their expectations are and how we foster communication, please refer to our Stakeholder Analysis and our Engagement Policy under Downloads.


Material topics

GRI 2-12, 2-14, 3-1, 3-2                                                        

A materiality analysis was carried out with twelve internal and external stakeholders at the end of 2020 to determine the material topics for strategy and reporting purposes. This took place in accordance with the GRI recommendations and was conducted virtually by the Sustainability Department at Implenia Switzerland Ltd. as external experts.

Following prior discussion, participants were asked, based on a list of potential material topics de-fined beforehand (see list on p. 8), to rate the respective topics from 1 (low) to 10 (high) according to the two following criteria:
•    Strategic relevance: Extent of the negative or positive business impact
•    Reporting relevance: Relevance of the topic for stakeholder assessments and decisions

In the follow-up to the materiality analysis, topics classified as material were identified and discussed with the Management Board of Ina Invest and given suitable objectives (see section ESG goals). Those topics that were classified as being of little relevance from a strategic perspective but were rated ma-terial for reporting purposes by the stakeholders, have been included in the present report.

Sustainability organisation

GRI 2-13, 2-14, 2-17, 3-1, 3-2

Doing business sustainably is a cross-sectional task, which affects all operations along the value add-ed chain and requires the commitment of all a company’s employees and partners.

The Management Board of Ina Invest is responsible for these topics. In collaboration with selected investors, developers, operators, and tenants, it defines the sustainability strategy, targets and initia-tives and gives an annual status report to the Board of Directors.

Thanks to the close partnership with Implenia, the Management Board and Board of Directors of Ina Invest receives assistance from Implenia’s Sustainability Department. It has several years of experience in sustainable project development and execution and ensures that the sustainability requirements of Ina Invest are included correctly in development and execution by Implenia Ltd. This partnership en-sures that there is a constant transfer of know-how relating to relevant ESG topics across all phases of the project, as well as between Implenia and the Management Board and Board of Directors of Ina Invest, and that interfaces are efficiently bridged.

“Ina Invest consistently centres on people. We invest in a liveable, sustainable and inspiring future – and actively help shape it.”


of the development portfolio boasts a building or site label

Our goal

Each project is certified in accordance with the requirements of an energy and/or sustainability certificate. We seek to achieve a 5-star Green Star rating according to the GRESB Benchmark Assessment across the entire portfolio.

To reinforce the high sustainability value of each project and make it quantifiable, all Ina Invest projects are certified in accordance with a national or international sustainability label. The company seeks to achieve the Swiss SNBS standard as standard because its sustainability requirements are so compre-hensive, as are the methods used and the flexibility it offers. From acquisition to operation, all our projects undergo a standardised testing and implementation process. Depending on local circum-stances, other labels are also permissible provided that the reasons for choosing these labels are explained.

Pre-project and acquisition
Even before purchasing land or an existing property, each project is assessed using various environmental, social, and corporate governance-related criteria. The assessment is based on Implenia’s appraisal tool GeNaB® (for residential space) or the SNBS Pre-Check (for office and commercial buildings). We only pursue projects with a high sustainability value.

At the pre-project stage and with the help of the development team, each project is assessed once more to decice whether SNSBS is the most appropriate label for the project-specific circumstances. Here, we focus particularly on grey energy and emissions, separability, and renewable energies and materials.

The fulfilment of sustainability criteria is also the top priority in construction. Project-specific environ-mental concepts are defined and implemented to prevent or limit environmental emissions. Material approval procedures guarantee the use of safe and environmentally friendly materials. We will main-tain these procedures by training construction personnel and using a targeted partner selection pro-cess throughout the entire procurement process.

During operation, we ensure that each project is optimised with respect to energy consumption as well as water and waste management. The users benefit from activities relating to ESG (environmental, social and governance) topics that are designed to increase community involvement, social interaction, and health and comfort.


We set ourselves the goal of listing all building materials used in a database to be able to determine the material quantities used and their current market value at any time. By making this data transpar-ent, we aim to sell the materials on the secondary raw materials market prior to the actual dismantling phase, thus closing the material cycle.

More information on the sustainability requirements for projects can be found in this document on the website of Ina Invest.

We work with partners that are committed to sustainability, and incorporate this requirement in the contracts awarded. We also ask our partners to ensure that their supply chains are sustainable.
