Encouraging environmental sustainability

As buildings account for 40% of our energy consumption and 36% of CO₂ emissions over their lifecycle, we need to start a new era of more sustainable construction and responsible building management.

Sustaining life

The built environment is a major source of carbon emissions and consumer of natural resources. Our services help developers, property managers and homeowners combat climate change and protect the environment by reducing greenhouse gas emissions and mitigating biodiversity loss.

Services with a positive impact

In all our operations, we seek solutions that reduce either our own or our clients’ carbon footprint, for example by improving the energy efficiency of buildings. A positive climate impact can be measured by a carbon handprint. A carbon handprint expresses the climate benefits of using a product or service, as opposed to a carbon footprint, which describes the negative climate impact of a company’s activities.

Our carbon footprint

As a service provider, Sustera’s carbon footprint mainly arises from office energy use and business travel. In 2025, our total footprint amounted to 7,733 tCO₂e, in line with our 2023 baseline.

In 2025, our focus was on addressing indirect emissions from purchased energy. By renegotiating our office electricity contracts, we reduced Scope 2 emissions by 35% compared to 2023.

Our climate work is guided by short-term science-based targets that have been officially validated by the Science Based Targets initiative (SBTi) and documented in our climate roadmap.

Our carbon handprint

In 2025, the carbon handprint of Sustera’s Finnish operations was approximately 27,056 tCO₂e. Around 90% of this impact was generated through lifecycle guidance in construction projects.

Overall, our positive carbon handprint in 2025 was approximately 3.5 times greater than our carbon footprint.
