Home » ISO 21678 Certification – Sustainability in buildings and civil engineering works

Can You Get ISO 21678 Certified?

No. ISO 21678 is not a management system standard. It sets principles for building fair sustainability benchmarks. There is no accredited certification for it. To prove green performance with a certificate, choose ISO 14001 certification or ISO 50001 certification.

If you build or manage buildings, you need clear proof of your green performance. ISO 21678 helps you compare that performance in a fair way. Global Certification Services helps you apply its principles to your projects.

What is ISO 21678 Standard

ISO 21678 sets rules for creating and using sustainability benchmarks. It covers buildings and civil engineering works. It looks at economic, social and environmental performance.

A benchmark is a level you compare results against. ISO 21678 describes three types: limit values, reference values and target values.

The standard does not set the benchmark numbers itself. It tells you how to set them fairly. It works alongside ISO 21929-1, which covers sustainability indicators for buildings.

Why ISO 21678 is Important

Clear sustainability benchmarks matter for companies today. Customers want proof that you care for the environment. They want to see facts, not just promises.

If you use this system, you can show solid results about your green efforts. ISO 21678 helps you compare your data in a fair way. This makes your green claims much stronger.

Laws and rules around construction are changing. Many countries have stricter green targets. With ISO 21678, you are ready when rules change. This keeps your company safe from sudden rule updates.

With these benchmarks, your team can find and fix weak points quickly. You also save money and use fewer resources.

Using ISO 21678 is a smart move. You gain many strong advantages:
