How we contribute to sustainable urban development

Contributing to sustainable urban development in various ways is a key part of Castellum’s business. All our investments are made from a sustainability perspective. We have an ambitious sustainability programme, we have perhaps the toughest climate targets in the industry and we make sure all our new builds and major conversions are sustainability certified. We also participate in various urban networks, business associations and other social initiatives to promote safe, sustainable development in the cities where we operate.

Examples of major projects

Sustainability a natural part of all our development projects

We work for the sustainability certification of all our new construction projects. The most common certification is Miljöbyggnad, where new construction projects for offices are to achieve Gold level and logistics are to achieve Silver level. The projects with the highest climate ambitions are certified according to NollCO2. We also work to create premises focusing on health and well-being for its tenants; the GreenHaus project in Helsingborg for example is certified under WELL.

Making a difference together

We collaborate continuously with various partners to drive development, learn about new technologies and exchange experience. Some of the organisations that Castellum is a member of: EPRA Sustainability Committee, GRESB Benchmark Committee, Energimyndighetens Beställargrupp för Lokaler (BELOK) and Sweden Green Building Council. The company also collaborates closely with local energy companies, waste management companies, universities and colleges. Castellum supports several organisations that work for a sustainable real estate industry and has for example contributed with 192 600 SEK to Fastighetsägarna, 77 500 SEK to Sweden Green Business Council, and 1 507 000 to Citysamverkan-organisations in 2022.
