Gain insight into how sustainability systems work and what credible practice looks like, through ISEAL’s interactive online training courses for anyone working in the sustainability sector.

ISEAL’s 2026 training programme brings together a series of expert-led courses designed to strengthen understanding of how sustainability systems function in practice.

As public and regulatory expectations on sustainability performance continue to rise, businesses, sustainability systems and civil society organisations are increasingly expected to demonstrate that their systems are credible, effective and deliver impact. This requires strong design and a clear grasp of how different elements operate and interact in real-world contexts.

Building on recent years of delivery, these training courses support a shared understanding of credible practice and help participants work more confidently within a range of sustainability systems.

Understanding sustainability systems

The training courses explore the core elements of sustainability systems and how credible approaches are applied. Delivered by ISEAL experts, each course takes place over three interactive online sessions, combining presentations, discussion, exercises and dedicated time for questions.

Participants gain a clear understanding of how different components, from standard-setting and assurance to monitoring, evaluation and learning, fit together, and how these can be applied in their own context.

The training courses also offer opportunities to engage with peers, exchange perspectives and reflect on different approaches. Participants receive access to ISEAL’s library of resources and guidance through the ISEAL Platform, along with a certificate of attendance.

The training brings together individuals from sustainability systems, business, civil society and consultancy roles.
