Report 2017/2018


Detailed information on our decarbonization strategy can be found in our current sustainability report.


It is our responsibility to reduce the resource consumption of our buildings. We monitor closely energy and water use as well as waste produced across our portfolio. Based on these values, we identify measures to reduce consumption and thus operating costs for our tenants and increase our independency from the energy grid.


We deliver our objectives by setting ambitious targets and constantly monitoring their progress.

Target 1
Procurement of 100% renewable energy for areas within our control by 2020

We intend to power all the common areas of our portfolio and the entire area of our own offices with only renewable energy by2020. This way, we can achieve our goal of cutting the emissions that we can influence to zero.

Target 2
Procurement of 50% renewable energy for tenant areas by 2040

We intend to use 50% renewable energy for the electricity and heating needs of our tenants by 2040.


We participate every year in external sustainability indices and ratings. Our strong performance is evident in the following results. In 2019, we decided to report only on the ESG (environmental, social and governance) indices that we consider significant to our business.

Please note that other indices may provide alstria’s ESG performance without receiving our feedback. This may lead in representing not the full picture of our strategy.


Continuous improvement on data quality and transparency have been key developments of our reporting through the years. This is displayed in our annual sustainability report, which provides insight into our strategy, targets, actions and performance.

Tenant Electricity Pool

We offer our tenants and employees alike an attractive framework contract to procure 100% renewable energy and thus help them reduce their carbon footprint. This project received in 2017 the immobilienmanager Award for the category sustainability. We are glad to see since then that other companies have been replicating this approach. The more, the better!


Our long-term vision is that sustainability becomes everyone’s daily job routine to achieve all our self-imposed goals. For this reason, the alstria CSR Committee at the Supervisory-Board level meets twice a year to monitor the strategic direction of our sustainability practices. Furthermore, the Code of Conduct communicates our values to the public and protects the rights of our employees and service providers.
