TS EN ISO 21416

TS EN ISO 21416 is a standard for recreational diving services that focuses on environmentally sustainable practices and combines requirements with guidance for service providers. Its core purpose is to define how diving-related services can reduce pressure on aquatic environments while supporting positive outcomes for nature and users alike.

Activities and service providers in scope

The standard applies to recreational-diving-related services and is not limited to scuba diving; it also covers snorkelling and free diving (breath-hold diving). The emphasis is therefore broader than a single dive method and centres on the responsibilities of the organisations and professionals that plan, manage or deliver these services.

In general technical terms, environmentally sustainable diving practice involves avoiding damage to seabeds and coastal habitats, interacting carefully with marine life, reducing waste, and adopting behaviour rules for sensitive sites. The idea is to keep the diving experience enjoyable and safe in a broad sense while helping preserve the aquatic environment over time.

Best-practice guidance for stakeholders

The standard also provides guidance to all stakeholders involved in recreational-diving-related activities on best practice. That includes operators, instructors, guides and other parties involved in service delivery, supporting a shared framework for minimising negative impacts and optimising positive environmental outcomes.
