At SECO, we don't see sustainability as a buzzword, but as a crucial building block for a better future.

It's a philosophy that gets to the heart of everything we do. For more than ten years, we have been working closely with our stakeholders to achieve material ESG goals and support sustainable construction projects.

Sustainability starts with fostering deep respect for our planet and a shared ambition to create a lasting impact, so that we can pass on its beauty to future generations. At a time when governments, real estate developers and companies are facing increasingly stringent regulations and challenges, we at SECO created this specialized unit: Sustainable Impact by SECO.

This unit has been specially developed to guide you through the complexity of sustainable construction and providing security, so that you are not only prepared for the future, but also actively shape it. We offer the expertise to make the sustainable transition not only possible, but also tangible and measurable. We help you turn your ambitions into concrete results that are both impactful and long-lasting.

The added value of independence

Independence and reliability are the cornerstones of our work. We take these responsibilities very seriously–we know that the quality of an assessment can make a difference in a world where anyone can claim that a building or project is sustainable.


The need for an independent, professional party that can provide objective technical reports is invaluable in every construction project. SECO guarantees reports that do not need to be re-verified because we have set the highest standard from the start. Our technically substantiated reports are therefore trusted by your insurers, banks and investors.

Our independence assures you of the feasibility and reliability of your sustainable projects. With Sustainable Impact by SECO at your side, your sustainability claims are firmly rooted in technical expertise and impartiality.
