Low-carbon design principles of alstria

To accelerate the pace of decarbonization, we have set low-carbon design principles. Our low-carbon design principles are the basis of our construction activities toward decarbonizing our portfolio.


We report under the Real Estate Carbon Accounting Principles (recap), its (unaudited) carbon balance sheet and carbon profit and loss.


The intention is to allow better understanding and visibility of the impact of the transition a carbon lite economy will have on our business and facilitate the conversation with our stakeholders using a familiar reporting framework. Introducing a balance sheet, moreover shift the focus from solely operational carbon, and better account for embedded carbon. We not only discuss carbon price, but we also discuss its value.

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 have set science-based targets to ensure that our decarbonization pathway is in line with what the latest climate scenarios say is necessary to meet the goals of the Paris Agreement.

Target 1: Company emissions

Continuous procurement of 100% renewable electricity for areas within our control.

Our goal is to minimize our company-induced emissions to zero as early as possible. To this end, we have already achieved our RE100 target in 2018 to power all the landlord shared services and the entire area of our own offices with renewable energy and will continue doing that. We have also started electrifying our company’s vehicle fleet and offering low carbon alternatives for business travel and commuting.

Target 2: Tenant emissions

Reduction of emissions from downstream leased assets by deploying renewable energy and low-carbon heating.

Our goal is to reduce the tenant-induced emissions in our portfolio by more than 30% by 2030. To this end, we systematically advise our tenants to join our renewable electricity pool. Wherever possible we also switch to low-carbon heating systems like electric heat pumps, district heating/cooling or other alternatives.


We participate annually in industry-recognized indices and ratings to track our environmental, social and governance (ESG) performance. Below you will find our results over the past three years. If you are interested in earlier alstria ratings, please contact us personally.

Please note that other rating agencies may provide our ESG performance without receiving our feedback. This may lead in representing not the entire 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.
